Canon PIXMA MP610 worked until Friday. Saturday the printer does not copy and does not print from computer, but does print maintenance functions (alignment, etc.) so it isn't the printer head. Discovered today (Sunday) that saving a .docx as a .png, the iMac can send the .png that will print, but the .docx sent still prints a blank page Printer scanner continues to print only a blank page in copy mode.
Any solutions?
