Your printer is actually complaining about the print head and not the individual ink cartridges. There is a known problem with the cartridge clogging up and overheating when many CDs are printed.

First try to remove and reseat the actual print head: remove the ink cartridges first, then pull up the grey lever and take out the print head. Check for visual damage and/or clean but be careful with this.

Reseat the cartridge, put the ink tanks back in.

If this does not result in a working printer, order a new printhead from your local supplier.

Remove and check cartridge on right. I have removed it several times but still comes up with message and will not work


All I did was replace my black ink cartridge with a new one and it works. You think it would say replace ink cartridge instead of remove and check cartridge on right. Good Luck.

Full cartridges = empty :S


Solution 1

Once you remove the ink cartridge from the printer, you can make use of the Isopropyl Alcohol, and put at maximum of 10 drops in the ink cartridge. You will find a hole there, in which the ink usually runs from the ink cartridge to the head of the printer. When done, you can put the cartridge back in the printer and run the auto cleaning process from the printer's option in order to clean the blocked holes of the cartridge. I would suggest you to run print tests first and once you are satisfied with the results, you can start using the printer normally.

If you want to go further:

* Remove the tank.
* Connect a hose directly on the inlet ink.
* Locate the sensor of reservoir and press it to make as if a cartridge is available.
* Close the cover of the print head and clean the head by injecting air (under pressure) through the pipe.
* Replace the tank up and do a test print.
* Repeat the procedure several times if the nozzles are clogged.


Solution 2

Using a syringe and some alcohol to unblock the holes can also be very effective.

* Step 1: Remove the cartridge from the computer
* Step 2: With the syringe, take in some alcohol and put in some drops in the tiny hole where the ink runs from the ink cartridge to the head of the printer.
* Step 3: When done, put the cartridge (only where the tiny holes are found) in some warm water. If some ink runs in the water, it means that the holes have been unblocked.
* Step 4: Hence, let the alcohol act for 20 minutes on the ink before putting the cartridge back in the printer.
* Step 5: Run some test prints before using the printer normally.


Note: I would suggest you to do an automatic head cleaning each time before any printing task. Hence it will reduce the risk of having the print heads blocked by dried ink.

Replaced black ink cartridge and it says its low


Some newer printers, such as Lexmark, will have a place in the properties app that allow you to "tell" the printer the cartridge is new. Check yours and see, it fixed mine.

On the front of the cartridge there is a sight tube for the ink, the fax shines a light through this tube to detect the ink.
I wraped a piece of paper around the tube to block the light beam on all the cartridges.

Ink tank


Users having problem like ink cartridge is only partial used, but error code appear to check ink cartridge, maybe trying to taking out and putting back, it works sometime and problem occurs again,
  • By replace a new ink cartridge will sure help as the partial used one would be faulty already, and if you are using Canon ink cartridge, do call up Canon to report the issue and they will exchange a new ink cartridge for the faulty partial used cartridge as it due to the unique feature that Canon has build on the ink cartridges not properly done, which resulted to be faulty. Canon's purpose is to prevent the usage of 3rd party ink cartridges.

Hi, You need to get a new ink cartridge. It is really not recommended to refill ink cartridges but if you do then it is advisable not to exceed 3 times because it could damage the printer head. If the new inks still gives error, then your printer head may need to be checked to see if it needs replacing. Good luck!
