Question about Canon PIXMA MP780 All-In-One InkJet Printer

1 Answer

Canon Pixma MP780

We have this machine since summer 2006. It happened once when we change the cartridge it could not print at all. After few hours we try printing it worked. Again this happened first right after we change the cartridge it came out with faint printing and suddenly nothing printed at all. We have checked the cartridges it is alright.

Please let us know what shall we do?


Thank you.

    My Pixma MP780 has been a champion. But, suddenly - nothing prints. I have gone thru the head cleaning, deep cleaning, alignment - and nothing comes out - not when you cue a document, try to copy or get a fax confirmation. I am super frustrated. I just had it in for service for 3 days to empty the waste tank. It worked great after that...this just started yesterday - HELP!!

I simply want to set the printer to print confirmations and also to know the code to print a confirmation report at days end.

I have to ask this question of you, just to make sure this is not an issue. Are you using a factory new ink or toner cartridge?
Please consider the following:
If you are using a refilled (the absolute worst possible choice) or third party cartridges (2nd. Worst possible choice) 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 or toner causing problems with print quality or damaging the physical printhead or photo conductors.
If you are using factory new ink or toner cartridges, then please call the manufacturer’s Technical Support for assistance with the warranty on the cartridges

Can not print media


Basically ##343 means the waste ink absorber needs replacing (soaks the spilt ink up under the cartridges).

Link to an official Canon service manual. That should tell you how to change it.

Canon Pixma MP780 "Wrong Cartridge" Error Message


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.
