This is my first so I apologize for any errors:
I have a Canon Pixma Multipass MP240 Inkaholic printer.
Despite massive amounts of cartridges, and endless cleaning cycles by the printer the print quality is faded.

I have contacted Canon who advised uninstalling and reinstalling the drivers (problem: I have the printer installed on 2 separate NON-networked computers. And both are faded)

I have "cleaned" the print heads (with the software that comes with the printer) a number of times.
The "check patterns" show no problem.
I have also replaced the cartridges.

I need a technical / service manual for the MP240 (or for one that is similar).
I have "fixed" epson printers (clogged print-heads) in the past.

Thank you in advance!
