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

1 Answer

Canon MP780 has gone crazy!

It makes copies on its own without hitting buttons. It won't fax.
Seems to have a mind of its own. Worked fine until yesterday. I tried unplugging it overnight but same problem exists today.

Reset the device when it is not functioning properly.
If the device is not functioning properly or to clear memory, reset it.

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

  2. Wait approximately ten seconds and then press the <ON/OFF> button again.

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

were the copies from the computer or something you tried to copy before?

My canon pixma mp780 is not responding. I unplugged the cable and replugged in, turned off the computer and it still is not reponding.

Make sure that your computer still sees the printer. Go to printers & faxes and check. If it is gone reinstall software.

Printer is not working

It is possible that the FAX in the memory is causing the problem. Try unplugging the printer from the wall and leave it off for a minute or two to see if it will clear the memory

My PIXMA MP780 always says "Warming Up" when I try to fax or scan. It never warms up. The machine prints fine- doesn't do much else.

My incoming faxes won't print. both black ink cartridges r full

Is there any message when you try to print the faxes?

If there is an "Image Quality" message, probably the printer is set up to "Copy" in "Photo" or "Fine" mode and it needs to be set to something other than "Fine" or "Photo"

MP780 copy mode/resolution

Mine was stuck on fine photo resolution too and it wouldn't print in normal black. I tried lots of things and the only thing that seemed to work was pushing the photo button and then pushing the copy button again. Good luck.

Blurry Scanning/Copying

Are you scanning both black and white and color the same way? The ADF (automatic document feeder) uses a different scanning area than when you place the document on the scanning glass. If you open the scanner cover, look to the left of the main scanner glass to the narrow strip used for the ADF. Make sure this narrow strip is clean -- no ink or white-out or scratches. This can make your copies look dirty or smudged.

Printer prints top 1" of page, then just spits out blank pages

If the printer works ok on another PC, it seems quite clear that the problem is definately software (Driver) related. If you haven't done so already, I recommend adding the printer through the Printer\Faxes Add Printer Wizard and pointing it to take the drivers off the install CD (if you have one) rather than installing the printer from the CD Autorun. Just make sure that you've deleted the printer completely from Printers\Faxes and rebooted before each install attempt.

I hope this helps!
