Recently I have printing problems (colors) with my printer: every 3cm, the ink is interrupted by white horizontal lines.
I first checked the ink cartridges (these were ok), them executed cleaning printheads + outlining several times. I made an update of the software. Then I changed the cartridges to check if anything changed.
The result stays the same...
Very strange that printing in greytones is still quite ok. The result of colorprinting is very poor and unaccepable as an output.
