Repair Information Removal and Cleaning Precautions Observe the following precautions whenever you service the printer: • Be sure to unplug the printer from the outlet before attempting to service the printer. • To reassemble the printer, reverse the order of removal unless otherwise specified. • Do not operate the printer anytime during removals. If it is absolutely necessary to run the printer with its covers removed, use care not to allow your clothing to be caught in revolving parts such as the gears, rollers and fan motor. • Never touch the terminals of electrical parts or high-voltage parts such as the high voltage unit. • Be sure to handle the fuser carefully as it remains hot for a while after the printer stops running. Always unplug connectors by holding the connector housing. • Be sure to use the fuse listed in the parts catalog. • Remember to install the ground wire or ground plate to ensure positive conduction. Install the screw with a toothed washer in the correct position at reassembly. Repair Information 4-1
