Question about Canon PIXMA MP780 All-In-One InkJet Printer
The main black print not working all of the time. Now there is no black printing (e3). The blue is streaky - no solid lines. If printing green there are streaks of green and streaks of yellow.
What is the best method for cleaning the printhead or does it have to be replaced?
That definitly sounds like it needs to be replace, have you tried using the printhead cleaning utility?
