The printer is charged but still prints. Reasons for poor printing of refilled cartridges. The cartridge is original, but it has already been refilled

The cost of cartridges is high and sometimes comparable to the price of the printer itself. Therefore, it is not uncommon to refill a cartridge to save money, because in this case you only need to pay the cost of ink or toner.

So, you refilled the old cartridge with ink, installed it, but printing “does not work.” In such cases, it is not always necessary to give up the old cartridge.

Let's look at common reasons for printing failure with full cartridges:

1. The ink is dry. Downtime causes the ink filling the nozzle to dry out. To rinse or clean the cartridge, place it in warm distilled water or alcohol so that the nozzle is completely immersed in the liquid. After 5 minutes, remove and wipe off any drips.

2. Incorrect installation cartridge after refilling or lack of appropriate printer drivers on the computer. Make sure that nothing gets between the contacts of the printer and the cartridge. Then make sure the lid is closed and all protective films have been removed. Install or reinstall the driver again.

3. Chip. Almost all modern cartridges are chipped, which leads to a count of printouts. Upon reaching a certain limit, the chip blocks printing. You can try to flash the chip yourself or contact a specialist at a service center.

First thing to check

USB cord and power cable. It would be good to reconnect them (connect to another USB port on the computer).

Canon counter reset

Then, if you refilled the cartridge yourself, you need to try resetting the chip or resetting it to zero.

How to reset the copy counter on Canon printers or cartridges:

As soon as the message about lack of ink appears on the monitor, click “OK”. Next, press the “STOP/RESET” button on the case and hold it for 10-15 seconds.
On Canon iP series printers, you can use the IPTool 1.1.5 utility to reset the counter. You can find it on the Internet.
For printers and MFPs Canon MP210, MP160, IP2000
1. The printer must be turned off. Click the “Continue” button;
2. Without releasing it, press and hold the “Power” button;
3. Without releasing the “Power” button, release and press “Continue” twice (the color of the indicator will change: green - yellow - green);
4. Release the "Power" button;
5. When the indicator stops flashing, press “Continue” 4 times (the color of the indication will change again);
6. Press the “Power on” button (the indicator will blink 1 time);
7. Press the "Power" button again and wait until the printer turns off. Ready.

If these options do not suit you, try searching for ways to flash the chip online.

If you refilled a cartridge at a service center, then they should have flashed it and notified you about it.

If the cartridge is refilled and flashed

If no actions after refilling the cartridge resuscitate your printer, then most likely you need an original cartridge. If this does not help, then you need to take the device to a service center.

Have fun typing.

In recent years, many Canon printers have used separate ink tanks. Or rather, all printers except cheap or very old printers..

What can we do if we see that after refilling the cartridge, the Canon printer does not print? Few people have probably thought about it, but any of the ink tanks contains only a specific color of dye, and the common print head is inserted on a carriage.
The most common case of why a Canon printer does not print or prints poorly after refilling the cartridge may be that each ink tank has a specific, unique chip that is used as a counter for the number of pages that have been printed by us. Such ink tanks are usually marked CLI-521, CLI-8, PGI-520Bk, PGI-5Bk. In fact, this technology is the most economical. Thanks to this, you can control each color separately and regardless of their volume, quantity, ink that is still left in each of the inkwells, and then, when one runs out, you can replace each of them separately.
In addition, with the new single print head, you can also control the size of the droplet that is applied to the paper - from 2 to 1 picolitre! This also has a positive effect on print quality and color mixing.

In addition, the new single print head allows you to control the size of the droplet applied to the paper - from 2 to 1 picolitre! This also has a positive effect on print quality and color mixing.
However, due to the fact that the ink tanks are chipped, when the ink runs out, the device will stall, and very often after replacing the cartridge, the Canon printer does not print until the ink tank is replaced. Many users refill ink tanks, but after refilling such a cartridge is still not recognized by the printer as full, and the problem still appears when a Canon printer prints poorly after refilling the cartridge.
Depending on the model of the device, the cartridge chips (and the “pampers of the devices, where the ink is drained when cleaning the print head) can be reset or reset using the programmer. If, after refilling the cartridge, the printer does not print Canon mp250, you can also disable counter tracking in the device menu or device driver settings.

Canon printer does not work after refilling cartridge

You should not confuse the ink counter in the cartridge and the waste ink counter - the so-called “diaper” counter, and what to do if after refilling the cartridge the printer does not print Canon mg3540. They reset differently.

The ideal case for resetting cartridge chips is when you have a programmer that is sold in online stores. If you do not have it, then the refilled cartridge installed in the printer will be detected as empty. In this case, you can try disabling monitoring of ink levels in cartridges.

Information about the ink level in chips installed in cartridges of Canon Pixma printers with separate ink tanks such as iP4200, iP5200, etc. cannot be reset or reset.

In order to understand how to start a Canon printer after refilling a cartridge, the operation of the printer was not blocked when the ink level in the cartridges reached zero, according to the chip, you need to disable the printer's monitoring system for the ink level in the cartridges.

Canon MG 2440 printer does not print after refilling

After the printer reports that some cartridge is out of ink, you need to press the paper feed button. This is the middle button with a triangle and a flashing indicator. Keep it pressed for 10 seconds. After this, the printer will turn off the ink level monitoring system for this ink tank. Now the printer will not block work. If you occasionally receive messages indicating that the cartridges are low on ink, simply ignore them.
Resetting the ink counter using IPTool and MPTool utilities

Manufacturers of printing devices are making attempts to improve the combination of price and quality in the technology they produce. However, the problem still remains relevant. This also applies to a failure in the printer, which, after refilling the cartridge, refuses to print. How to get out of this situation?

Where can I find a universal manual about the operation and use of the printer? Let's look at these solutions using examples.

So. You purchased an inkjet printer, and after printing a few photos, you find yourself in a difficult situation. The culprit turned out to be a color cartridge that had exhausted its resources. Buy new? If only the prices were exorbitant. To resolve the issue, it is best to fill the tank yourself.

What should I do if the printer does not print even after refilling the cartridge?

How to find possible causes and eliminate them? First, to find out why the printer stopped working, make sure you have the correct supplies and review the refill process you followed. After all, you might have missed something. For example, often, in order to save money, owners of this equipment buy low-quality ink. It may also be that the cartridge is a non-refillable type. Many users have superficial knowledge and find it difficult to avoid mistakes. To prevent this from happening, try to carefully study the presented article and maybe you will be able to detect a mistake and correct it.

First reason.

After refilling, the cartridge does not print due to ink incompatibility. Your actions: study in more detail the information where it is indicated what type of paint should be used in your modification. Universal inks may not always be an acceptable option. It will be more profitable to buy more expensive original paint. Of course, you should pay attention to the date of manufacture and period of use of the “artistic substance”.

The second reason may be printing.

Various consumables are produced for inkjet printers, including disposable ones. In addition, the printing element itself may not be refillable. Therefore, it is worth looking at its markings. If the cartridge is truly not refillable, a special chip is placed in it, which does the work until all the ink in the containers is used up. Then, the device owner needs to buy a new component. To avoid this, it is better to immediately purchase a slam-shut valve with a higher capacity. This choice will be reflected in the future on the comfort of service.

The third reason is the most common.

Dried up. If the slam-shut valve is left inactive for a long time, the paint may dry out in it. To prevent this from happening, it is necessary to seal the output holes in the print head with a special film, and then wrap it tightly in a plastic bag. Then the influence of air will be neutralized. But if the cartridge has dried out, there is no need to despair. Very often it is restored.

The fourth reason is called air.

Do not allow air to enter the inside of the cartridge chamber. Otherwise, this may become the root cause of this problem. Air bubbles prevent the paint from passing through. To prevent this from happening, after filling the slam-shut container, you should close the filling holes with tape.

Fifth reason. Hardware.

It happens that the user installs the cartridge incorrectly. As a result, the contact plate in the printer cannot reach the receiving pad or is not positioned properly. It may happen that the device interface is dirty. When refilling cartridges, this may well happen.

Eliminating the main causes of the problem one by one when the printer refuses to print after refilling.
Print head recovery occurs in different ways.

It all depends on the type of cartridge.

Step one.

Cleaning the nozzles using the printer. You need to print a diagnostic page and run several full cleaning cycles with the refilled cartridges.

Step two.

The cartridges were refilled incorrectly. After refilling, the printer will not print if the seal is exposed to cold temperatures. If the cartridge has been in the “wrong position” for some time, ink has flowed out of the print head. In this case, problems may also occur. You can print in test mode a few hours after you install the cartridge in the printer.

Third step.

Cleaning the nozzles using a special liquid. When, after refilling, the printer refuses to print, and the cartridge has been inactive for some time, the cause of the breakdown may be dried ink in the nozzles. In order for the printing element to work again, you need to perform some actions. Place a piece of medium-hard fabric at the bottom of a shallow container and place the cartridge on it. Without a special cleaning solution, pour in glass cleaner to saturate the substrate. Leave the cartridge in this state for 12 hours. Then carefully wipe the print head dry with a napkin. Install the safety shut-off valve into the printer and perform complete cleaning several times.

Restoring the non-removable print head.

We looked at troubleshooting a combined slam-shut valve. That is, where the container and the printing element are installed together. But there are also cartridges that get clogged easily. To clean the nozzles of such modifications, a simple device is made. A syringe is taken and a rubber tube is placed on it. Its diameter should be equal to the needle protrusion of the print head. Fill the dispenser with recovery fluid. You only need a few milligrams, then pressurize this liquid into the cartridge. Remove the syringe after a few hours and install the paint container. The printer can be cleaned several times.

In this article, we looked at the main reasons for printer failure when, after refilling the cartridge, it refuses to print. Now you know what to do in this situation. All that remains is to apply the acquired knowledge in practice. However, do not forget about the simple rules regarding the operation of printing equipment. The main condition for long-term operation of cartridges is not to leave them inactive for a long time.

Since the price of a new cartridge remains high and is almost equal to the cost of the printer itself, many users, in order to save money, resort to refilling the ink tank themselves. But, despite the fact that the cartridge is full, in some cases the printer refuses to print.

Main causes of the problem

Before troubleshooting the cartridge, you must check the cordUSB. Oddly enough, sometimes this cable is the cause of problems. If you don't have a spare cord, try moving all the connectors or connecting the cable to another USB port on your PC. If these actions do not improve the situation, then you need to look for other reasons why the printer does not print.

Ink has dried out in the nozzles

U inkjet printers There is one big drawback: after a short period of time, the ink in the print head nozzles dries out. To prevent this from happening, you need to print something all the time, or turn on the printer once every few days (from 3 to 7) so that it “blows out” the nozzles.

Air got in when refueling

Air in a cartridge filled with ink will not cause much harm. Unless the paint begins to leak out of it, since there will be no necessary vacuum inside the container to keep the ink from leaking.

It's another matter when the ink runs out and air gets into the print head nozzles. In this case it is possible drying of paint in the capillaries of the head. Air can also get in and dry out the head if it is parked incorrectly after the printer has finished running. It is important to check that the carriage always reaches the parking space. Only in this case will the nozzles be protected from drying out.

Air can also damage the print head, especially in Epson printers, since it is non-removable. The problem is that when changing ink tanks, if this is done leisurely, or when installing a CISS when the head is outside the parking unit, the nozzles have time to dry out.

Ink is not selected correctly

Some users think that ink is the same for all printer models. But in fact, even for devices of the same brand, ink may differ. The cartridge may not print due to incompatible ink being filled into it, which entails a complete flushing of the print head.

You should also pay attention to ink expiration date.

The cartridge is not installed correctly

Sometimes a situation arises when the printer does not see the cartridge. This is explained by the fact that there are electrical contacts on it, which, when installed, must perfectly coincide with the contacts located inside the carriage. If for any reason there is a contact failure (dust, dried paint), the device will not work normally. It is also necessary to peel off protective film from contacts, if the inkwell is new.

Some devices, especially MFPs, will not start working until cover open. The cause of equipment failure lies in a special lid sensor. Therefore, if you have installed a CISS, and the cable from it prevents the lid from closing tightly, then this sensor must be blocked, for example, with a piece of foam plastic (blocking methods may differ for different printer models).

Problems with the chip or diaper counter

Inkjet printers use two types of cartridges: disposable and refillable. In disposable ones, the manufacturer installs a special chip that blocks the operation of the device after the ink in the container runs out. Even if you pour paint into the reservoir, the chip will still signal that the container is empty. The printer also refuses to print if the diaper counter indicates that it is full.

A diaper is a place in the device filled with foam rubber, where excess ink from the print head is drained.

Troubleshooting Brother printers (MFPs)

To resolve problems with a dried out print head, diaper, chip, etc. There is no universal method, since the design of the devices is different. Different printer models have their own troubleshooting methods. Brother MFPs most often refuse to print after refilling the cartridge due to dried out nozzles or overfilling of the diaper.

Brother machines use both water-based and pigment ink cartridges. Usually pigment ink has a “black” cartridge - they become the culprits for clogging the print head if the device has not been used for 3-4 weeks.

Brother MFPs, unlike other models from different manufacturers, are designed in such a way that the ink tanks are located to the side and connected to the print head via silicone tubes (cables), similar to the cables in a CISS.

The paint, as usual, dries not in the cable or cartridge, but in print head nozzles (PG). Therefore, you first need to get to the head. In standby mode, this unit is parked in a locked state. If you open the lid, you can see the assembly, but you can’t move it.

To release the head from the lock, do the following:

turn on the device and wait for it to fully configure itself;
run a nozzle check with the scanner unit closed;
As soon as you hear the movement of the printing mechanism, you should unplug the power cord from the outlet to stop the movement of the carriage.

Now you can manually move the carriage in any direction. To restore the nozzles, it is necessary that the flushing liquid gets onto them in some way. The simplest method is to use for these purposes parking space:

you need to take a napkin and fold it 3-4 times;
place the napkin over the entire surface of the mouth guard;
heat the washing liquid to 40 degrees and thoroughly saturate the napkin on the mouth guard with it;
Using maximum care, move the carriage with the print head to the parking space, so that the napkin does not move and the nozzles are in close contact with the wash;
leave the carriage in this position for 5 to 10 hours (it is better to do the procedure in the evening and leave the “soaking” until the morning);
if the “soaking” did not give the expected result, then it can be repeated by replacing the napkin with a new one.

This method is quite effective if the case is not advanced. Otherwise, you will need to contact a service center.

Diaper reset

Brother printers do not have sensors that monitor the overfilling of the diaper with waste ink, and therefore the adsorber is controlled at the software level. The calculation is made based on the number of prints that came out of the machine, as well as on the number of head cleanings (forced and regular). After some time of operation of the unit, the program counter determines that it is time for the diaper to be overfilled and blocks the printer, while the message “Cleaning” or “Error 46” is displayed on the device display. To reset the counter, no additional software is required. The device has reset function via service menu

Unplug the device's power cable from the outlet.
While pressing and holding the “MENU” key, connect the power cable to the electrical outlet.
Wait for the “Maintenance” message to appear on the screen for a couple of seconds. At this moment, you need to have time to remove your finger from the “MENU” key. If that doesn't work, unplug the outlet and do it all over again.
By clicking on “+”, wait until the number 8 appears, then click “OK”.
Using the “+” key, select number 2, and then “OK”. After these steps, you should see the message “MACHINE ERROR” or “MACHINE ERROR 00”. If such a message does not appear, but some other message is displayed, then you will not be able to reset the diaper counter.

follow the steps above up to point 3 (inclusive);
then use the “+” button to select the number 0 and then press the “OK” button, the image “00:00 XX:XX” will appear, where XX:XX is the time;
Now you need to press the “BLACK AND WHITE” key (it, as well as the “COLOR” key, can be found near the “START” button) until the inscription “PURGE: xxxxxx” appears (instead of xxxxxxx there can be any numbers).

At the next stage, for the inscription “PURGE” you must enter the special code “2783”:

Use the “+” key to find the number 2 on the display and press “OK”;
further, “+” → “7” → “OK”;
“+” → “8” → “OK”;
“+” → “3” → “OK”.
after this you should see the message “PURGE:00000”;
by pressing the “BLACK AND WHITE” key, select “FLUSH: xxxxxx”;
repeat all the actions that were done after selecting the “PURGE” inscription;
after selecting number 3 and clicking “OK”, you will see the message “FLUSH:00000”, then turn off the printer, unplug it and turn it on again.

After the counter is reset, the printer will continue to operate. It is also recommended to remove the diaper itself, rinse it and dry it, but this will require disassembling the device. Understanding how to do this will require a separate article.

Solution for Canon printers

Printing equipment manufacturer Canon uses 2 types of print heads in its devices: non-removable and removable, located directly on the cartridge.

Cleaning Fixed Printheads

Before you start washing this part, you will need to prepare a small container in which the washing process will take place. This could be a saucer, a plastic box with small sides, a photo bath, etc. You will also need: gauze or bandage, a pair of syringes (10 ml), plastic and rubber tubes, which are found in medical droppers. Rubber bands will be needed if a strong blockage is found that cannot be removed by soaking.

For flushing, it is recommended to use flushing liquid, sold at ink stores. But, since the price of liquids is quite high, you can use household chemicals, namely “ Mister Muscle” (MM) for washing glasses, containing ammonia.

Please note that the color of the chemical is either green or blue. Other colors of liquid are not suitable for flushing.

Next, you need to remove the print head itself. Since there are a great variety of devices of this type, each case has its own nuances. A video of the process of removing the head for any printer can be found on the Internet.

So, when everything is prepared, do the following.

If a drop of liquid is not absorbed into the grate, leave it to soak for a while. From time to time, remove it with a napkin and reapply. When the napkin stops staining, but the liquid still does not pass through, you will have to use the following washing method, which is used for severe blockages.

If soaking overnight does not produce results and the liquid in the tube does not drop, you can move on to the next method. But please note that you will be using it at one's own risk, since you can completely damage the PG, or more precisely, the nozzles. This is done as follows.

Important! If you cannot pull the liquid through the nozzles at all, then you should not try to push the liquid in the opposite direction (through the nozzles). This will cause the capillaries to rupture and the head can be discarded.

It is possible to push the MM through the nozzles only in a situation where at least a little liquid passes through the nozzles during suction. But even in such a situation, it is necessary to have experience in order to feel the permissible force that is applied to the syringe piston. The degree of sensitivity of the capillaries to pressure in different heads may differ, and to reduce the chances of damaging them, it is recommended to use larger volume syringes (10-20 ml), in which air will serve as a shock absorber.

If applied method of drawing liquid in two directions, then the following nuances should be taken into account:

if you use a 10 ml syringe, then the air gap between the piston and the liquid should be about three divisions;
at first, lowering the syringe plunger is allowed only by 3 divisions, no more;
as the liquid decreases, you can add one division at a time;
the pressure on the piston should be smooth, without jerking.

You should know that complete cleaning of the steam generator with an average degree of blockage takes from one to three days. If the blockage is severe, the procedure may take up to a week. You need to be patient, because the desire to do everything quickly can completely “kill” the head.

There is another, extreme method of washing nozzles, which is called “ shower”.

Draw MM into the syringe, but without an air gap.
Connect it to the pipe using a tube (from the system) about 20 cm long. This is done so that the pressure is compensated by the length of the tube. In extreme cases, when you exceed the pressure, it will jump off the pipe, splashing liquid all around.
Lift the PG above the saucer and begin to press the piston without much effort.

The result can be assessed by the way the liquid flows out of the nozzles. If they are not yet completely rinsed, then the stream looks like the figure below. By the way, this type of jet can be observed when the nozzles are destroyed, which can also be determined visually.

The following picture shows that the liquid comes out in smooth, thin streams, reminiscent of a shower. This means that the nozzles are well washed.

Before installing the head into the printer, it is necessary to “drip” it so that it is not dry. To do this, place a few drops of washing liquid into the ink channel grids.

Don't forget to run a hardware print head cleaning to fill it with ink.

Cleaning the print head on the cartridge

This recovery method is suitable for both Canon printer cartridges and HP ink tanks that have a built-in head and look schematically as in the following figure.

First, you need to determine whether the cartridge is really dry if the printer does not print. To do this, take toilet paper and press it against the bottom of the ink tank, where the nozzles are located. If the ink imprint on the paper is clear, then the head has not dried out. If there is no print or it is weak, then the nozzles need to be soaked. The easiest and fastest way to soak is to apply a few drops of MM to the nozzles. To do this, turn the part upside down with the nozzles, as shown in the figure.

After 10 minutes, remove the liquid from the nozzle with a napkin and check whether the paint passes through to the paper. If this method does not help, then you can let the part soak for a longer time (2-3 hours) in a container with MM.

For better penetration of liquid to the nozzles, you can place, for example, a piece of a toothpick under the inkwell so that the nozzles do not touch the bottom of the container, but are immersed in the solution.

After soaking, you need to wipe the part dry with a napkin, especially the contact group, insert it into the printer and start deep cleaning. Then run the nozzle check test. If you are not satisfied with the result, you can try blow the nozzles through the air intake hole in the cartridge.

To do this, do the following:

cut the medical needle to half and put it on the syringe;
in order to ensure a tight fit of the syringe to the body of the inkwell, any soft rubber band should be placed on the needle;

insert a syringe with air into the hole of the cartridge and press it tightly so that the elastic band ensures a tight fit;

begin to gently push air into the inkwell, after placing a piece of toilet paper or napkin under it;
as a result, ink should flow from the nozzles;

“Color” cartridges that have 3 holes on top are also purged in this way.

Resetting Ink Control

Canon ink tanks have a chip installed that counts the amount of ink remaining in them. When, in the “opinion” of the chip, the ink runs out, an error message appears or about an empty cartridge. Therefore it is necessary turn off the counter.

If Canon PG510 / 440 / 426 ink tanks are installed, then press “OK” in all messages that appear on the device’s display. Press “OK” until a message appears asking you to press the button to enable paper feed. Hold it down for a few seconds and the paint counter will be reset. For other cartridges, the reset occurs after pressing the button with the image of a triangle in a circle for 5-10 seconds. or in the printer settings on your PC.

We revive Epson printers

Ink accounting in Epson printers is done by their own software (firmware). Therefore, no matter how much ink you add, the program will consider that the container is empty and block printing.

To return the device to operation, it is customary to use PrintHelp program, which is freely available on the Internet and is free. In addition, it can be used for most Epson printing equipment.

Using this program, you can not only reset the ink to zero, but also monitor its quantity. The program is also able to detect the overflow of a diaper and, if necessary, reset it.

Print head restoration

To flush the print head in Epson printers, you will need a special cleaning fluid or “Mr. Muscle” for glass. In most cases, There is no need to remove the carriage from the PG, and washing is carried out as follows.

Turn on the device with the lid open, and when the carriage is in the middle, unplug the cord from the outlet.
Remove the ink tanks from the carriage. If you have a CISS installed, then read the instructions for it, which tells you what to do to remove the cartridges.
Manually move the carriage slightly to the right, place a clean napkin on the bottom of the machine, and move the head so that it is above the napkin.
Cut a tube 5-10 cm long from a medical dropper.
Place the tube on the syringe and draw MM into it.
Insert the tube into the hole through which ink flows from the ink tank to the head (the hole leading to the clogged nozzles).
Pour a couple of cubes of liquid into it and wait until it seeps onto the napkin. It is also recommended that the remaining nozzles do not dry out while you are washing one area, and pour liquid into other holes.
Do this procedure several times, changing the napkin.

Upon completion of washing, do the following: remove the napkin, remove possible drops of liquid from the device, insert the ink tanks into the carriage and, turning on the device, start enhanced cleaning of the PG.

In a situation where this method of restoring the head did not help, you will have to remove it from the printer and use the restoration methods that were previously described for the removed head of a Canon device.

Restoring HP printers

To clean the print head in HP printers, located on a cartridge or free-standing, the method described for Canon printers is suitable.

Resetting the ink counter

It's no secret that HP 121, 27, 28, 56, 57, 21 and 22 ink tanks are refillable. In this case, you need to be careful and not allow the ink to be completely depleted by refilling it on time. When the chip detects that the ink is running out (but there is still paint), a message is issued about this: an exclamation mark appears next to the problem ink tank. In this case, you need to click on “Continue”, thereby disabling paint level monitoring. The disadvantage of this method is that you will not be able to see the ink levels.

If you do not add ink after this and continue to print, then after it is used up, a sensor that determines the actual amount of ink will work and block the operation of the printer and the chip itself. And a cross will already appear opposite the cartridge. If this happens, you will have to replace the chip or ink tank. Although there are several ways reset the chip to display the paint level.

Place the inkwell on the table with the contacts facing up and do the following.

The meaning of these manipulations is this: four different cartridges are replaced, after which information about the identifier of the refilled ink tank is erased from the device’s memory, and it, inserted fifth, is considered as new. After this, the printer will assume that there is paint and display its level in the containers.

The second method is suitable if the first one was ineffective:

seal the first contact, insert the inkwell into the machine, and print the test as in the first method;
Without removing the sticker from the first contact, you need to glue three contacts with a rhinestone, as shown in the figure;

insert the part into the machine and print the test;
remove all stickers and return the ink tank to its place, remembering to clean the contacts with alcohol.

Manufacturers who produce modern printing devices try to make their products as useful and easy to use as possible. But, unfortunately, they were never able to solve the problem of poor-quality printer printing, which almost every user faces.

What will we talk about:

The printer does not print at all after installing a complete consumable

Why the printer does not print after refilling the cartridge is a question that often worries every owner of this device.

This behavior of the device can be explained by one of the following reasons:

The selected ink is not compatible with your Canon, HP, or other printer. To avoid this, you need to select the appropriate type of ink for refilling the cartridge. Its shelf life is also important.
The cartridge has dried out because it has been left idle for a long time. Flushing or replacing it can solve the problem.
The consumable was installed incorrectly.
Your Canon or HP printer does not have the required drivers.
The chip responsible for printing is blocked. This can happen due to exceeding the paint consumption limit.

For these reasons, the Canon printer does not print after refilling the cartridge. This situation can also happen with devices from other popular manufacturers.

Faded printing after refilling the printer

It often happens that after refilling the cartridge the printer does not print well. If HP or Canon starts producing faded prints, then the following has happened:

The model is equipped with inappropriate or low-quality toner. Refuelers are not always able to select the right element for a specific device. This is the answer to the question of why the printing machine may malfunction.
If the device does not print well, it means that individual elements of the cartridge have been damaged. Refilling it only makes the problem worse.
Faded print may be due to dust in the laser gun of a Canon, HP or other company. The presence of a layer of dirt on the LED strips also leads to this result.

There are other reasons that explain why the HP printer does not print properly after refilling the cartridge. Poorly displayed text or a picture on the sheet indicates a malfunction inside the device. If the user observes this after refilling the consumable, then he should take the device to a specialist for diagnostics.

Streaks appear on sheets during printing after refilling the printer

Why does the printer print in stripes after refilling the cartridge? This is another question that worries users.

This reaction can be observed for several reasons:

The cartridge was not fully refilled, so the ink in the HP, Canon or any other company printer quickly ran out. There is only enough dye to print a single strip on paper.
The ink in the head of the consumable that allows the device to print has dried out.
A head malfunction has occurred. Also, after refilling the cartridge, the printer prints poorly due to the failure of the cable. As a result, a stripe appears on the sheet.

Reasons why a white or black sheet comes out of the printer

If a white sheet comes out of the device during operation, a software or technical failure is to blame.

In the first case, the reason lies in the following:

The file has become corrupted.
A required driver is missing.
The device settings are set incorrectly, causing it to print blank sheets.
There is a software conflict.

If the cartridge is refilled and the user is sure that there are no glitches in the software, it means that errors were made on the technical side:

Installation of low-quality toner or drying of ink in the cartridge.
Incorrect consumable firmware.
Damage to the port on the device side.

It is extremely rare, but still, users have to deal with a situation where a black sheet comes out of the printer.

The device prints paper that is completely covered in ink for the following reasons:

The photodrum has been illuminated. This part allows the device to receive information from a connected computer. For it to become unusable, you just need to expose it to the sun's rays. The light instantly damages the photodrum. Correct refilling of the cartridge does not affect this in any way. Over time, the situation will resolve itself. If the device continues to print poorly, the damaged part will need to be replaced.
The contacts were dirty. This problem is very common. This can happen if the contacts of the consumable come into contact with the contacts of the power supply. It is not advisable to clean dirty elements yourself, as they are easily damaged.
The device prints black sheets due to the lack of a corotron (a special wire for supplying voltage). The refueler may simply forget to put it on after finishing the job. This problem is common among inexperienced craftsmen and users who independently fill consumables with ink. And this is one of the reasons why such tasks should still be trusted to professional craftsmen.
There is a malfunction in the high-voltage power supply or other important part. In this case, there are no complaints about the consumable. The whole problem is hidden in the device itself. To determine this, you need to install the cartridge in another device and check the quality of its operation on it. If the sheets print normally, then the breakdown is in the machine, which means it needs urgent repairs.
The wrong paper was used. Every user should know that sheets intended for faxes cannot be used for laser printing devices. During operation of the device, they heat up and turn black.

Professional diagnostics will allow you to recognize the correct cause of the printing machine malfunction. Only after identifying the breakdown will it be possible to say whether the refilled cartridge should be blamed for the poor-quality printing or whether a malfunction in the device itself led to this result.
