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

1 Answer

Print Quality My printer is producing fuzzy lines and some with a white line through the line of print and some lines appear almost italicized. I inherited this all-in-one when I took over this office and there is no User's Manual for me to troubleshoot with. Thx. Also, just today, I started getting a "Wrong Cartridge" message. What's this about?

Probably needs a new printhead. had this error message with mine and cured it with a new head. Try removing all the tanks, then remove the head (lift the grey clip on top and it will just lift out) Run warm water over the in ports inside until no more ink is washed out then thoroughly dry and replace - see if that works
