konica minolta c220 lines

[adecanmin]

Gentlemen
I have a c220 that is making lines on the prints, copies. If I want to make a gradation sheet there are no lines. I enclosed a picture. This is a yellow print in test mode. I'm thinking mfpb. I would have to order one.

I changed the prcb no lines. All that's left is the mfpb.

Did you do some kind of factory initialization on the machine. How does the managment list from SM print out. Clear with no lines?
Lines are only Yellow?

The lines were there before I did anything. The lines are on a b\w print as well as color. I have not printed out a management list.
