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

WRONG CARTRIDGE and Printhead does not move MP780

I have a wrong cartridge error. However, I cannot access the printhead since it does not move when I open the cover. The printhead remains stucked in the right corner. BTY, I'm not using OEM cartidges, just cheaper replacements. Any suggestion will be appreciated.I have a wrong cartridge error message but the head does move into position when cover opened. I can't seem to clear the error. I reseated, and changed the cartridges.

    The problem I reported was incorrectly posted. My problem is similar but not the same.

    I get the message "wrong cartridge" but have OEM cartridges. The print head behaves as expected. The printer is locked out by the error code and will not print.

    The probem persists. I had unplugged for at least 5 minutes. As soon as unit is powered up, the error light is flashing with the same code as before.

  • mthibault610 Feb 24, 2009

    How can I be sure the print head replacement will solve problem? It seems to be a connection or something to me. How do you remove the carraige?

Dear mthibault610,

RE: Canon PIXMA MP780 All-In-One Ink Jet Printer "Printer Locked Out by Error Code & Will Not Print"

Is the above referenced printer the one your telling us about?

If so what is the error code?

Have you tried unplugging everything attached to it for a least 1 minute then rebooting as suggested already?

    Try resetting the printer :


    1. On the operator panel, press and hold the button for one second. (The display will go blank.)

      Note: It may be necessary to unplug the power cord if pressing the ON/OFF button does not shut off the printer.


    2. Wait approximately ten seconds and then press the button again.


    3. Wait until the device has completed its cycling process before submitting another job request.

    Gently push the cartridge carrier to the center remove all the cartridge and remove print head allow these steps :

    # Hold the printhead 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.

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.

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 WRONG CARTRIDGE and Printhead does not move MP780 - cb_transparent_l.gifus.gifspace.gifspace.gifspace.gifspace.gifspace.gifspace.gifspace.gif1-800-828-4040cb_transparent_r.gif, 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.

Disconnect the power from the printer for 5 minutes and then open the door and see if the print head moves over, u may have shorted the printer out due to a defective cartridge.

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.

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 ...

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.
