New developer unit and pcu but it still comes back, I thought it was coming from labels but they stopped using them. The ITB unit looks good but that is the only thing close to the drums.. Nothing on it. I talked with another tech and he has had the issue as well but he said it never came back. Any ideas? I am tired going out every two weeks to clean off the drum. Thanks for any input.
