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

1 Answer

Won't print in black

I have the very same problem that is described on this page: http://www.fixya.com/support/t181776-pixma_mp780_printer_not_printing Before I changed the black ink cartridge, it showed to be half full. I changed the black ink cartridge because your solution (link above) said to. The problem is still there. Nothing is different. The screen still shows the cartridge to be half full. I am using Canon ink cartridges. FYI, if I am printing grey letters, they print. But if I change them to black, it produces a clean unprinted page. Thanks for your help.

Open your list of printers. r/click on the 780 and open properties. fo to the last tab "maintenance" and run cleaning 2 or 3 times then run deep cleaning 2 or 3 times. and see how this helps. If you've never done it before you might want to take out the print head and clean it with alcohol. Take out all the ink like you were changing them then reach in and gently pull out the container that holds the ink. This is the print head. Clean it and replace it, then run clean and deep clean again. run Nozzle check to see how clean it's become and you'll definetly see a difference in your printing. good luck

Pixma MP780 that will not print


Hi

If you have installed the driver and can print out a test page that means your computer is communicating with your printer.

Try to use wordpad and before you print, hit on ctrl-p then choose the pixma as your default printer. then try to print the document, you can use microsoft word as well for testing.

keep me updated

The MP780 is not a wireless printer. It must be connected via a USB cable. Please see the information here:

My printer will not auto align and will not print a complete grid when I try to align it myself. Currently I get nothing when I try to print and my ink tanks are all full

You can copy and paste any of these links in your internet address bar under a new tab to take you to your manual page.

You will need to realign the alignment, and print an alignment page. Or reset printer.

Canon pixma mp600 printer will not print documents.


This will be because your black pigment (the large cartridge) will have clogged in the printhead.

Cleaning it can take a while and I've already posted a solution for this, for an MP780 so I'd take a look at that and see if it helps you solve your problem.
http://www.fixya.com/ThreadView.aspx?prdid=360551&thid=3076115

Oh and the reason your web pages print ok? It's because the printer is using a combination of the other inks to create black, not printing black directly... PDF's and document printouts are different as they DO use the pigment black...

Hope that helps.

Can not print media


Basically ##343 means the waste ink absorber needs replacing (soaks the spilt ink up under the cartridges).

Link to an official Canon service manual. That should tell you how to change it.
