Question about Canon PIXMA MP780 All-In-One InkJet Printer
By mistkae I bought 3E MYC installed and have been using them for about a month with no problems. Today the "WRONG CARTRIDGE" message started to flash and sheets feed through but nothing prints. I replaced the 3E MYC with 6MYC (all are OEMs), but it still says "WRONG CARTRIDGE" and does not show full tanks on the display. I have tried all the maintenance options...no luck. Is this a print head thing too?
PIXMA MP780 "WRONG CARTRIDGE" MESSAGE?
Here is what I did and it now works just fine.I turned off the printer and unplugged the power cord, and unplugged it from my computer. I then removed all the ink cartriges and removed the print Head I got some rubbing alcohol put it on some toilet paper and wiped down the back and bottom of the print head.Plugged everything back in and It now works better then ever.

I can tell you that the MP780 does not know the difference between a BCI3 and a BCI6 cartridge so there is definitely another issue.

Gave the print head a good washin' with water and even after using head cleaner and alcohol (I was doin' the drinkin' tryin' to fix this thing) it came back to life.
Thanks for the info

the mp780 would only read mp 750 when i installed the printhead
so i took it to a place where cannon recommended and they said it is the board which is over 300 dollars to fix because cannon is trying to phase out the mp 780 printer
the printer is working fine only cannot do printing of the cd's dvd's
the mechanic said it worked perfectly till he turned it off and when he turned it on again it reset at mp750 so it is telling him it is the main board/logic..
so thank you all for your assistance:):)
