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 s witch turned on after rem oving 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 removi ng and in sta lling the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the s afety interlock by inserting w edges or other items into the switch slot.
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.
The foregoing is applicable only to the 220V

At the production line, the output power
of the scanner unit is adjusted to 0.57
MILLI-WATT PLUS 20 PCTS and is
maintained constant by the operation of
the Automatic Power Control (APC).
Even if the APC circuit fails in operation
for some reason, the maximum output
power will only be 15 MILLI-WATT 0.1
MICRO-SEC. Giving and accessible
emission level of 42 MICRO-WATT
which is still-less than the limit of
CLASS-1 laser product.
Caution
This product contains a low power laser
device. To ensure continued safety do not
remove any cover or attempt to gain access
to the inside of the product. Refer all
