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.

CAUTION

INVISIBLE LASER RADIATION,

WHEN OPEN AND INTERLOCKS DEFEATED.

AVOID EXPOSURE TO BEAM.

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

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

servicing to qualified personnel.
