Re: Canon Pima MP500 Printer.Despite running cleaning settings for print head and rollers ectc,I am still getting a 1cm wide line of black ink through the length of the reverse side of printed pages. Please advise on how to resolve. Many thanks

Black printer ink in Canon Printer may fail to be recognized by the printer. Most times an error message will be sent indicating that something is wrong with the black print cartridge. Sometimes the printer may accept to print with the black ink, but the printouts may have horizontal lines and very illegible letters. In such a case a manual cleaning of the print head should be carried out. In doing the manual cleaning, one should spray Windex heavily on paper towel and wipe off the surface of the print head.

Ink tends to overflow at the bottom guide rollers and the roller gets coverd in ink and causes the black line!The best will be to take it to a dealer and have it cleaned!Good Luck!

You will need a shop to dismantle the printer, the ink is being forced up onto the exit rollers from below. It needs a good cleaning plus a mylar shield installed to keep that from happening again.

Cleaning only made it worse. The ink is coming from the cleaning assembly, and you need a shop to clean up the ink and install a mylar shield to keep that from happening again. The ink absorber gets plugged and the ink comes up thru the exit rollers.

The ink cartridges on your Canon Pixma MP500

YOU CAN TRY PULLING THE CARTRIDGE OUT AND WITH A CLEAN , VERY SOFT CLOTH , CLEAN THE HEAD GENTLY ....SOME CARTRIDGES ARE JUST FAULTY ....HAVE YOU TRIED RETURNING IT OR GOING TO CANON SITE AND TROUBLESHOOTING ?

HI Foster,
The problem is not with the print head. Print a blank page and if you are still getting the streak. Something is probably trapped in the printer or the rollers are dirty.

I hope it helps!!!

We have the same problem. I removed the cartridges, then removed the print head. There was lots of ink gunk on the print head. I cleaned it and the problem disappeared completely for a few days but is now back. I suspect the print head needs to be replaced. Still working on it.

I have same problem, with new ink cartridge, also tried cleaning the print head, no luck.
