Cannon MP500, new ink now printing black line on back page

Jamming is surely not related to ink replacement, however the blank page may indicate there is dried ink blocking the stream of the new one since you are probably not able to clean the path of the ink i highly reccomend to call the local service technician or replace the related parts on your if you have possibility to do so.

Hello
Please replace or re-fill the black cartridge.
Good Luck

If the error you get is "The following ink tank cannot be recognized" have a read here on Canon support website on how to fix it, they have visuals as well http://support-au.canon.com.au/contents/AU/EN/8000138710.html

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!

ink on one of the guide rollers will cause this

For some reason, the printer is designed to dump ink into the bottom of the tray before feeding on the paper. The paper is then dragged over the ink, leaving the black line. This is a software issue, not a hardware one. I'd advise that you update all of your print drivers, as well as your firmware.

A temporary fix is to clean the rollers and base plate of the printer for ink spills.

Check for any bits of paper or debris that may be caught in the printer. Be careful to feed in the paper perfectly straight, as this printer does not have good rollers, and it will cause paper to break off and cause problems. If any debris has caught or absorbed ink, it will cause the back of the paper to smudge, and you have black lines.

if you do your own refill the ink u are using is of the wrong density, get the right ink

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.
