General Cleaning (if needed)
Whenever you check, service, or repair a printer, you should perform the following
procedures. Cleaning the printer, as outlined in the following steps, assures proper
operation of the printer and reduces the probability of having to service the printer in
the future.
The frequency of use and the type of paper a customer prints on determines how
critical cleaning the machine is. Users of ordinary Bond paper (copier paper) should
have very few problems since this paper is smooth and relatively dust-free.
Ask each printer customer about the type of paper he or she uses so that you can be
sure to clean the parts of the printer that particular paper may affect. If a customer is
printing on the more unusual or dustier papers, then you should pay particular
attention to these printer parts:
1. Turn off the printer.
2. Remove the Print Cartridge and immediately cover it to protect the drum from the
light.
3. Remove the fuser.
4. Remove the paper trays.
5. Clean all printer rollers, except the Bias Transfer Roller, with a lint-free cloth
dampened slightly with cold water.
Caution: Never apply alcohol to the Bias Transfer Roller.
