Parts marked with " " are important for maintaining the safety of the machine. Be sure to replace these parts
with the replacement parts specified to maintain the safety and performance of the machine.
This document has been published to be used for
SHARP CORPORATION after sales service only.
The contents are subject to change without notice.
CAUTION
This product is a class 1 laser product that complies with 21CFR 1040 of the CDRH standard and
IEC825. This means that this machine does not produce hazardous laser radiation. The use of controls,
adjustments or performance of procedures other than those specified herein may result in hazardous
radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved
on the eye's retina, there is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of
servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a
unit, not as individual parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, toner
cartridge, and drum cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected
when removing and installing the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

during initial installation and whenever the copier is moved.
Caution: If the copier is moved from a cool place to a warm place, con-
densation may form inside the copier. Operation in this condi-
tion will cause poor copy quality and malfunctions.
Leave the copier at room temperature for at least 2 hours
before use.
Do not install your copier in areas that are:
· damp, humid, or very dusty
Do not expose the drum cartridge to direct sunlight.
Doing so will damage the surface (green portion) of the drum cartridge,
· exposed to direct sunlight
causing poor print quality.
· poorly ventilated
Store spare supplies such as drum cartridges and TD cartridges in a
dark place without removing from the package before use.
If they are exposed to direct sunlight, poor print quality may result.
Do not touch the surface (green portion) of the drum cartridge.
Doing so will damage the surface of the cartridge, causing poor print
quality.
· subject to extreme temperature or humidity changes, e.g., near an
air conditioner or heater.
3. Checking packed components and
accessories
Open the carton and check if the following components and accesso-
ries are included.
Power cord
The copier should be installed near an accessible power outlet for easy
connection.
Be sure to connect the power cord only to a power outlet that meets
the specified voltage and current requirements. Operation manual
Also make certain the outlet is properly grounded.
Be sure to allow the required space around the machine for servicing
and proper ventilation.
