I have problem with two copiers Sharp MX-2300N. When I printing or coping color on the page have random vertical thin color line.

did you clean the laser lens? how about the transfer belt/roller?

charge roller/corona?

not really sure what you mean by " I change everything without power supply board "

Looks like the cleaning blade to me but I could be wrong based off paper orientation.

I get parts from other copier - transfer, drum, laser unit, main boards without power board and HV board.

If you are running LTR-R (short edge) you may want to rebuild the K PCU. Looks like drum/cleaning blade?

but it's a magenta line... i would look at magenta drum

You have 2 lines on your image. I'm going to assume your paper orientation is letter-r (short edge fed)

Red line (rebuild your magenta drum)

yellowish brown line (looks like primary transfer cleaning blade issue) Pull the belt and inspect it. You should see it.
