D. Cleaning during a Service Visit
Following the procedures below, clean the printer during service visit.
1. Transfer charging roller
As a general rule, the transfer charging roller is not to be touched or cleaned. If it is unavoid-

or solvent. Make sure not to contaminate the roller with solvent or oil.

roller
Clean with lint-free paper, either dry or moistened with ethyl/isopropyl alcohol.

Clean with lint-free paper. If badly contaminated, use it with ethyl/isopropyl alcohol for rubber

removal of the springs.
