Question about Canon PIXMA iP90 Mobile Printer
I recently had my printer cleaned and replaced the cartridges. I deep cleaned the unit, and the test page prints perfectly. Unfortunately, when I print 4 x 6 prints of photos on glossy paper, I get horizontal green and red lines through the bottom of the picture. I'm sure this is some sort of maintenance issue. Anyone have any suggestions.
It sound's like an ink-feed issue:
1) Dirty heads, even after cleaning
2) No-ink or poor quality ink
3) Damaged head: some are part of the cartridge, some are not
4) Air bubbles in ink
The test page is typically not as hi-res nor as saturated as a
photo print. The hi-res photo puts the greatest demand on the print head.
The color lines you see are actually lines of missing color,
where the head has failed to deposit ink, so one or two primary
colors are missing from the complete picture.
For example missing yellow will make a blue line.
Missing magenta will make a green line
Missing cyan will make a red line.... etc..
Clean the heads again and again, print again and again,
hoping to flush the system.
BUT, keep in mind that cleaning wastes huge amounts of
ink and tiny little cartridges of ink cost more than many new printers.
