1-1. PRECAUTIONS FOR DISASSEMBLY/ADJUSTMENTS
Observe the following precautions whenever servicing the copier.
© Be sure to unplug the copier from the outlet before attempting to service the copier.
© The basic rule is not to operate the copier anytime during disassembly.
If it is absolutely nacessary to run the copier with its covers removed, use care not to allow your clothing
to be caught In revolving parts such as the timing belt and gears.
® Be sure to use the Interlock Switch Actuating Jig whenever it is necessary to actuate the Interlock Switch
with the covers left open or removed.
® Do not plug in or unplug print jacks on the Board or connect or disconnect the Board connectors while
power is being supplied to the copier. :
© Do not use flammable spray around the copier in operation.
@ The Magnet Roller of the Imaging Unit generates strong magnetic force. Do not bring it near a cathode-ray
tube or watch. ;
© Do not use an air gun or vacuum cleaner for cleaning the ATDC Sensor and other sensors, as they can
cause electrostatic destruction. Use a blower brush and cloth. If a unit containing these sensors is to ba
cleaned, first remove the sensors from the unit.
@ When handling the PWBs with MOS ICs, observe “Instructions for Handling the PWBs with MOS ICs.”
@ When handling the PC Drum, observe precautions given in “Handling of the PC Drum.”
® Note that replacement of a PWB may call for readjustments or resetting of particular items.
@ Use the right screw in the right place at reassembly. Note that some are longer and some are thicker than
others.
@ A toothed washer is used with the screw that secures the ground wire to ensure positive conduction. Do
not forget to insert this washer at reassembly.
© To reassemble the copier, reverse the order of disassembly unless otherwise specified.
© If it becomes necessary to replace the thermal fuse or any other fuse mounted on a board, be sure to use
one of the rating marked on the blown fuse.
Always note the rating marked on the fuse, as the rating and mounting site or number used are subject
to change without notice.
@ Donot pull out the Toner Hopper while the Toner Bottle is turning, as a damaged Toner Replenishing Motor
or locking mechanism could result.
If the copier is to be run with the Front Door swung down, make sure that the Toner Hopper is in the locked
position.
