Hi there,

using a Canon IPF 9000.
Print quality of this plotter is amazing!

But the printer heads (pf 03) die in less than one year!
No matter how much you print.
I Don't think the print heads done in this time. Think Canon want sell print heads..
The problem is that the the printer block the printing untill new printerhead
change.
Is there a way to unblock the message "change print head"?
May be in service mode? Please help..
