howdy,
I bought a new black cartridge for my canon printer a few weeks ago. I've refilled the cartridge quite a few times with some cheap ink and I'm getting decent results. However, a fragment of the print head must have been clogged or sth as I've noticed this: (only on low and standard, works OK for high quality)
I've tried all types of printer cleaning utilities but I'm still getting those white lines.
I poured some 'cleaning liquid' into a jar's lid and put the cartridge for 30 minutes there but it hasn't solved the problem.
Any ideas how to clean the head?
