Hello, please help...
I have the following problem with my KM c350:

When printing b/w there are lines on the paper, can be seen in the attached image. The arrow shows the paper movement direction.

The problem is gone when I'm printing paper type: thick1, thick2, thick3 (or normal paper in thick1,2,3 mode), also when printing colour, and gloss print. In one word there is no problem when the paper is moving slow. I have cleaned the LED arrays on all colours.

Thank you in advance.
