Cleaning the drum unit C a Take out the drum unit and toner cartridge assembly, and then take out the toner cartridge from the drum unit. b Put the print sample in front of the drum unit, and find the exact position of the poor print. Troubleshooting and routine maintenance CAUTION The OPC drum is photosensitive so do not touch it with your fingers. Do not use a scrubbing or wiping motion because this might damage the drum. DO NOT clean the surface of the OPC drum with a sharp object, such as a ballpoint pen, because this might cause permanent damage to the drum unit. c Turn the white gear on the drum as you check the surface of the OPC drum (1). 1 d When you have found the mark on the drum that matches the print sample, wipe the surface of the OPC drum with a dry cotton swab until the dust or glue on the surface comes off. 131
