Canon Pixma MP780 "Wrong Cartridge" Error Message

Had this. Seem to have cured it with a new printhead (expensive!). I was able to get the printer to work for short periods by fiddling around and the print quality was fine. My question is, is there a way to disable or ignore this message so I could print anyway? I have cleaned up and stored the old printhead. Its possible to get into the Engineer Mode http://pixma.ulmb.com/?p=165/750-780.html but I don't have full details of all the instructions.

I have two Pixma 780's. After getting the "wrong cartridge" error one day when I turned it on, (I knew it was the right cartridge) I tried switching ink tanks, and the print head cartridge several times between the two printers. the problem followed the black print head cartridge, so I am guessing I need a new one. From that experience, I would recomend swithing the print cartridge if you get this error. Does anyone know how to do a reset on this machine? A Canon tech told me once, but I lost the info.

Canon support has a print head replacement (it's the black thing that the ink cartridges sit in) for about $50 including UPS ground shipping. Their phone number is 1-800-828-4040, part number is QY6-0049-000. I was going to buy one, but when I talked to the parts dept., they sold me a new one (with same capabilities, including duplex printing) for $120 plus tax and free ground shippping - with 1 year warranty on all parts. You can decide, mine was a few years old and is starting to have multiple problems, so I opted for the new one.

I have just changed all my cartridges and they are genuine Canon ones. I am getting WRONG CARTRIDGE message on my printer. Please help. thank you


Hi!

The printer reads the printhead as a cartridge too and the error is referring to the printhead that's faulty and needs replacement!It is an expensive part but can be replaced!Contact your local canon dealer and ask them for a quote on the printhead!

Good Luck!

It's a bad printhead, when it is removed, power should come back, but you need a new printhead. Wrong cartridge means the printhead is bad.

Error: ''Wrong Cartridge'' when no new cartridge has been installed


It is probably one of the cartridges. Usually, when the message "wrong cartridge" appears, the cartridge is faulty.

Receiving message stating "wrong cartridge"


Overnight I started getting the "wrong cartridge" message on my Canon MP780. I use only OEM cartridges. As the Canon website suggested, I replaced the printhead with a new one (Empire Office Machines for $48.25 plus shipping) and it works great. Prints better than ever. Easy fix for my machine. I did read that using refills can cause more problems than just the printhead.
