Question about Canon Office Equipment & Supplies

1 Answer

I have an Canon AIO PIXMA MP780. I keep getting a "Wrong Cartridge" message on my display. I first changed the cartridge that was out of ink, but continued to get the same error message. I even went as far as replacing ALL the cartridges--still no change. I shut down the printer, even removed the print head and tried to clean out the ink residue with no success. Is this the end of my printer? It was printing so well a couple weeks ago.

My canon pixma mp780 printer is giving the message "wrong cartridge". I did have a non canon ink cartridge in there, but now the cartridges are all canon, and I am still getting the "wrong cartridge"...


1. Remove the front printer cover.
2. Then take out the ink.
3. Next pull up the gray lever and take out the printer head.
4. Now go to the sink and start running the hot water. Then slowly and gently run the hot water over the metal part of the printer head. Use a soft tissue and gently clean the dry ink out.
5. Now dry the printer header with a soft cloth and wait for it to dry before placing it back into the printer.
6. Turn on your printer and see if it works now.

Hi, I see others have had this problem but can't find an answer (I am not still under warranty). Pixma MP780 suddenly giving a "wrong cartridge" error message. Have only used genuine Canon but have...



I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink cartridge?
Please consider the following:
If you are using a refilled or third party cartridge that may well be your problem. Most manufacturers build logic into their products to prevent the use of “Other Equipment Manufactured” cartridges as well as re-filled cartridges.
They do this to prevent problems from contaminated inks causing problems with print quality or damaging the physical printhead.
If you are using factory new cartridges, then please call the manufacturers Technical Support for assistance with the warranty on the cartridges

You get that message when the printhead goes bad. It's not the ink cartridges. You need a new printhead
