CAUTION
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.
LASER WAVE – LENGTH : 770 –795nm
Pulse times : 10.24µsec
Out put power : 0.15mW ± 0.01mW

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.

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.
The foregoing is applicable only to the 220V
model, 230V model and 240V model.

2. Note for servicing and handling
When the main unit power is repeatedly turned OFF/ON rapidly (for about 1sec), the IC (OA982) on the MCU PWB may malfunction to cause an error
(E1-00 Communication error), which does not boot the machine. In case of this error, the blank display is kept for several tens seconds and then "E1-
00" is displayed on the panel display.
<Countermeasure>
Turn off the power and keep it for more than 10sec. Then turn on the power.
When the machine is booted.: There is no problem in the MCU PWB.
When the machine is not booted.: The MCU PWB trouble
