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

1 Answer

Mp780 displays "wrong cartridge"

All of the ink cartidges were replaced before I realized that it is probably the printhead that needs service. Is that true? How do I remove and service or replace the printhead?

    NO - how do I do that?

    There is no "resume" button on this machine. There is reset, ok, and menu, but no resume.

Without realizing my mistake, I erroneously installed #3e Y-M-C ink cartridges instead of the correct #6 cartridges in my MP780. It worked fine for several days, then I got a message saying the printhead...


The fact is when you compare the cost to get a new printer to replacing your printhead and cartridges you find you may want to go for a new printer instead. The difference usually is not be worth it.

Good luck & God bless!

Got "wrong cartridge" error while attempting to print. Removed & reset all ink cartridges, still same error. Removed inks & print head, immediately lost power. Unplugged, waited, put everything...


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.

Cannon ink jet quit printing black


To solve the printing problem..

# Hold the cartridge upside down, with the bar-code label facing you and take a damp paper towel. # Use the towel to wipe the printhead of the cartridge on the bottom (where the ink comes out). Wipe the printhead horizontally in one direction only (left to right). # Continue doing this until it looks clean. # Then dab the cartridge on the towel to make sure the ink is flowing. # Next, look inside the printer and locate the carrier that holds ink cartridges. Caution: Make sure the cartridges are not installed at this point.
1. Look for a shiny piece of metal underneath the contacts at the back of the carrier. 2. Take a damp cotton swab (use water only!) and wipe along the bottom of the shiny metal piece. Note: You may need more than one swab.
# Reinstall the cartridges, making sure you snap them correctly into the printer.

How do I remove printhead?


same as when you change ink tanks...
1.follow the same procedure you use to change ink tanks/cartridges to remove the current ink tanks
2.remove all ink tanks/cartridges
3.the printhead is what the ink tanks/cartridges sit in, the furthest half of the part the ink tanks/cartridges sit on is the removable part/printhead, it is loose so you can simply reach in and carefully pull it out.
Easy as 123 ...

WRONG CARTRIDGE and Printhead does not move MP780


your printer ink cartridge can not access (move to middle) when you open up the cover, you may try
1) try to open right side cover you move the cartridge by hand (power off) to middle position, then take out the cartridge and reinstall it then power on, the cartridge moving right, you may open up the cover again if the cartridge go back the middle position which means your printer works normal. still stop moving go next
2) check the cartridge initcial sensor at righe side, the cartridge moving to the end of right should be touch this sensor, find out it and check there is good touch (click) by the cartridge body. adjust the sensor position maybe needed.
3) cartridge is stucked sometime also check the cartridge moving rail hard moving, need to drop oil to lubricate.
