Konica c452 regular horizontal line

hi everyone's
I have a Konica c452. that's scan and print is good But when I copy, it prints horizontal parallel lines! that are sometimes red and sometimes blue.
In the meantime I have set the time and date as well as the gradation adjustment.
I uploaded the sample copy.
where is the problem from?

 

Have you figured it out? I have the same problem. Thank you.
