I would recommend doing a full set of alignments in maintenance mode.
But i have already did it, I did all of alignments in service mode such as bi-directional, uni-directional and bi-d400, and all printers own tests are more than good, and only I start to print from onyx or photoprint - cyan and magenta have a double contour. This problem has occured suddenly, after deinstalling/installing yellow head. What it may be - cr-board? cr-sensor? virus? I think that my head will blow up cause of this.
