Hello everyone, i have Canon iPF670 and i have a color problem. at Print Quality: Fast 300dpi - the yellow color is missing in stripes; at Print Quality: Standart 600dpi - the yellow color is completely absent; at Print Quality: High 600dpi - everything is OK. Where is the problem and can it be fixed? I have ink in all cartridges about 80%. 3 times clean with "type А" and 2 times - "type B" and there is no result. But this morning I released one nozzle check pattern and then the plotter died and wanted to replace the printhead.

If you change the head, will it be okay or do you have a problem with the motherboard??
