I've got a lot of Canon iPF's 610 > 850 that are underused, requiring premature head replacements. Sometimes codes, sometimes poor color fill.
Just recently it was an iPF780 getting its third printhead this year ... averaging 1.67 ft2 per day, or approximately one Arch E1 print per week. Personally I think that if they printed at least one Arch E1 document with all the colors each week, the printhead could stay clear. I think it's the lapses of three weeks or more that dry up the head. Per the print log this customer prints (5) Arch D documents at the beginning of the month then does nothing the rest of the month.
Can you recommend a minimum paper volume or minimum ink usage (ml) to keep the printhead viable? Or maybe a minimum print interval? I want to recommend something, but so far all I know is what is unsuccessful.
