ROS (laser) is a very sensitive unit so that's why you will need a tech to remove it from the machine and to clean it.
Are you saying the C/K Laser is the issue, or that I would have a hard time cleaning it? Thanks for your reply.
You will need a tech to clean C/K laser.
Hello, I will be so grateful for the right answer here. I have a Xerox c75 color press. When I print greyscale I get consistent bands down the length of the paper (the same direction it is running). I have tried everything I can think of:
1 - Changed the Fuser
2 - Changed the 2nd BTR
3 - Changed the ITB belt
4 - Change the ITB belt Assembly
5 - Changed the Black Drum
6 - Changed the Black Developer unit
7 - Changed the black toners
8 - Changed the Blue Drum
7 - Tried to clean above the drums by removing them (read something about a laser).
None of these elements has had any impact. The lines are the same each time.
So I then opened the door while it was printing to see at what position the problem was occurring. It appears as though the toner on the ITB already has the lines. But I have tried 3 black drums and 3 black developer units. Grey are the only colors that have this issue.
