Do not connect or disconnect the power cord or other parts with wet hands.
An electric shock may result.
When replacing service parts, turn off the power, and disconnect the power plug
from the outlet.
An electric shock may result.
If toner gets into your eyes, do not rub your eyes, and wash the toner out. Visit a
doctor immediately. If ink stains your skin or clothing, wash with soap and water
immediately.
Be careful not to injure yourself or damage the Printer when working with box
cutters, screwdrivers, or other tools.

Cautionary Notes When Performing
Maintenance Work
When performing inspection/maintenance work, always be aware of the following items.
(1) Begin your inspection/maintenance work only after confirming with the user the current
status of the Printer and the state of the Printer when the trouble occurred.
In some cases there may not be any problem with the Printer itself, but instead it may be a
problem resulting from the use of non-standard toner/paper or a data problem, so always
check the status of the printer first.
(2) When disassembling the Printer to replace a part, make sure to fully understand how the
Printer is put together before taking anything apart so that you can smoothly restore the
Printer to its working condition afterwards.
(3) Allocate sufficient surrounding space for conducting your work.
(4) Be careful not to spill new/used toner. Also, place a sheet or cloth on the floor to prevent
staining of the surrounding floor area.
(5) Light-induced fatigue can affect the photoconductor drum. Avoid leaving the fuser unit
drawer open for long periods of time. When removing the photoconductor drum, cover it
with a black bag.
(6) Do not touch the surface of the photoconductor drum with your bare hands as it will cause
the drum to deteriorate.
If touched, wipe cleanly with a Ciegal cotton wipe.Any problems with image quality caused
by touching the photoconductor drum can be fixed by outputting a few dozen sheets of
paper.
(7) Keep screws, metallic washers, or any other magnetic materials away from the developing
sleeve. If any such part should get stuck due to the magnetic pull of the magnet roll, you
must remove those parts to prevent drum crush.
(8) Do not reverse the developing sleeve.
