Canon Multipass F80 printing is very faded.

sounds like there's something caught on the ink cartridge head. go to the canon ink cartridge information webs site to see if there is an answer there or in the manual that came with the printer. good luck

Are you using Windows Vista or Windows 7? If so, the driver download page at Canon does not provide drivers beyond XP. Otherwise, go back to the XP (or earlier versions) driver downlaod site and download the MultiPASS F80 Software User's Guide. That may provide the answer to your problem. Also, if you are using unpopular, proprietary software programs the driver may not recognize the commands. Good Luck!

When you print photos you print in Max dpi, for this no faded lines anywhere. Probably you have a problem only in black color in print head.
Мay be it's partially clogged or partially defective.

Replace the ink cartriges

You need a new printhead, QY6-0041-000 around $40.00

You assume correctly. Your printer uses all cartridges for printing, even for black only prints.

First you need to ensure that this is not a driver problem, by reinstalling drivers and testing the printer on a different computer.

Also ensure that ink cartridges are OK, try replacement inks.

If the problem is not a software problem, and the printer is recognised by computer, and the printout is coming as a blank or faded page, then you usually have a faulty or clogged printhead.

Try first performing print head cleaning procedure from printer tools, that may not fix the problem, but do the cleaning a couple of times, just in case.

If the print head is clogged, that can be fixed soaking the print head in isopropyl alcohol overnight.

If still no luck, then the printhead must be replaced, here is the part: Canon MULTI-PASS F-80 Print Head $61.00

Hi, I have washed my print head out with water and then alcohol. Cleaned my color printing right up.

Prints heads have to be alinged and or you let it sit too long without print and your print heads have to be cleaned

My canon F80 copies smear. How do I fix that?
