first.
4. When servcing or maintaining the MY-1015, be careful about the rotating or operation sections such
as gear, pulleys, sprockets, cams , belts, etc.
5. When parts are disassembled, reassembly is basically the reverse of disassemb ly unless otherwise

screws, washers, pins , E-rings, toothed washers to the wrong places.
6. Basically, the machine should not be operated with any parts removed or disassembled.

because the ICs on it may be damaged due to static electricity. Bef ore using the wrist band, pull out
the power cord plug of the copier and make sure that there is no uninsulated charged objects in the
vicinity.
