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

1 Answer

I have a Canon PIXMA MP780. It won't print except

I have a Canon PIXMA MP780. It won't print text except to eject the page. It gives no error. I tried printing a pdf file, and nothing printed except the larger font lettering, which is solid black on the pdf document, printed like the "outline" effect on MS WORD. Nozzle test prints fine. What can I do?

If you can print the nozzle test then that proves most of the electronics, it could be the driver is screwed.
Since you can get something out that is intelligent e.g. the larger font lettering then it is processing the file sent to it.
By that I mean rasterising it, converting it to dots of ink, so it can print onto the page as the heads moves back and forth.
Why not try another computer and connect your printer to that one, or try a different file, or even send it a file you've printed successfully in the past before you started to have this problem.

MP780 "check printer"


5200 is a printhead error, you may just need a new printhead. They do wear out, and just like a light bulb, they go out when you least expect. The part number is QY6-0049-000.

Unfortunately, I can't link you directly to canon's support pages, but if you go to this link, and enter won't print black and search, you'll get a list of possible solutions to troubleshoot this error.

Not knowing where you are from, I can only give the following help.

Do a Google search using the following text:

Note the "+driver" (no space between the "+" and the word "driver").
