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

1 Answer

Keeps restarting I have this problem. The printer is displaying "Wrong Cartridge". After a while it switches itself off and on again continuously. Have to pull the power cord to stop the printer. Sometimes it displayed "Cartridge Jam Press [OK]" and also restarted itself continuously with this message. Sometimes it displayed "Cart. Return" and restarts itself continuously with this message. With the "lid" open and ink compartment exposed, powering on the printer will start at "Cover Open" and stay on this message (not restarting itself). Once the lid is closed, the message "Wrong Cartridge" is displayed and after a few minutes, it started to restart again. I have cleaned the printhead contact with some alcohol and printhead path is clear. Is the printhead gone or there is something else wrong? Please help. Thanking you. JChiu

MP640 - After changing the ink-cartridge ,a message appear. "The following cartridge is unknown", U043

I would try opening the printer, make sure the ink cartridge is fully seated. Once that is checked, unplug the printer, wait a minute or so, then plug the printer back in and try to turn it on. If the problem persists, then try a new ink cartridge. If that doesn't work, there is something major wrong with the printer itself, and will be beyond anyone but a Canon repair facility to repair.

Installed new black cartridge - had ink

A firmware update for your model addresses the print quality problem that you're currently experiencing. Please visit the Lexmark website to download and install the Lexmark S400 Series Firmware Update. If more than one download is listed for your model, choose the first download in the list. If it is the wrong firmware level, an error message will tell you which firmware level is correct.
Should the error continue to display even after successfully updating your printer, please contact Lexmark Technical Support Center for additional assistance. Your printhead itself might be the cause of the problem.

Empty cartridge warning

Most problem experienced with hp photosmart c6180 is the yellow catridge error. Try cleaning the contact surface of the catridge and the printer using moistened cotton buds..if error continues, you should clear the error that keeps on displaying.. here's how: press & hold "*" key...while holding, press "#" key and then release both keys..."Enter Special Key Combo" will be "1", "2" and "3" to display "Support" ">" right arrow button and release when "System Config Menu" "OK" and/or arrow key to display "Hardware Failure Status" "OK"....when "Hardware Failure Status:Clear" appeared, press "OK" to "OK" again to display "Hardware Failure Status Cleared. Press Cancel To Continue" "CANCEL" as many times to display "Welcome To Photosmart Express" or "Ink System Failure".....the last part is to turn off the printer and unplug at the back...wait for 30 sec, then plug and turn on the printer...if asked, press "OK" to continue and allow the "One Time Ink Initialization" to procede..After this try to print...

Have Dell 3115cn printer, installed an Innovera cyan cartridge, and the dell keeps saying restart, will not read the cartridge

Probably a chip problem.

Its worth taking the cartridge out (with the printer switched on), close front door, wait for 'Insert C cartridge' message, switch off printer, put new cartridge in, close door, switch on - may clear the problem.

I've seen this before with these cartridges, there was a bad batch of chips around.

If still have your old cartridge, swap the chips over, and try your new toner with the old chip (and for completeess, your old toner with the new chip. If the message changes, the chip that was on the new cartridge is faulty. If it doesn't there's something wrong with the cartridge.

Either way, if there's a cartridge problem, it needs a word with the supplier.

HP C6280 says out of black ink

Something is wrong with your Blach carrier or connections. Use a bit of alcohol and clean the array of gold contacts where the Ink cartridge plugs in. Most of the pins are shutter and piezo control (get the ink on paper) but a few do other stuff like check ink level, # of hours runtime, etc. This is very common problem with inkjet printers. Hope this helps.
Also... rub the contacts on the printhead with a pencil eraser to make them shiny and bright.
