since 3 days, i have these blue stripes on every paper i've printet in color. They don't apear on black and white prints and i can't get rid of them. I've reseted the hole printer and don't have any errors.
Measuring the distance between two of the defects will provide a number that will correspond to a repetitive defect ruler measurement. As the marks appear to be cyan in color I would guess that you have an issue with the cyan cartridge.
