This laser printer is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH standard.
This means that this machine does not produce a 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 eyes
retina, there is 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 an
individual part.
2) Do not look into the machine with the main switch turned on after removing the toner/developer unit 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 upper frame of Laser Printer Unit contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

[4] installation
1. Site selection
Take the following points into consideration when selecting a site for
this model.
ENVIRONMENT
* The machine must be installed on a level surface.
* Keep the machine away from air conditioners, heaters, direct sun-
light, and dust.
* Provide easy access to the front, back, and sides of the machine.
In particular, keep the area in front of the machine clear, or the
original document may jam as it comes out after scanning.
* The temperature should be between 41° and 95°F (5° and 35°C).
* The humidity should be between 30% and 85% (without condensa-
tion).
ELECTRICITY
Standard voltage, grounded AC outlet is required.
Caution!
* Connection to a power source other than that specified will cause
damage to the equipment and is not covered under the warranty.
* If your area experiences a high incidence of lightning or power
surges, we recommend that you install a surge protector for the
power and telephone lines. Surge protectors can be purchased at
most telephone specialty stores.
TELEPHONE JACK
A standard RJ-11C telephone jack must be located near the machine.
This is the telephone jack commonly used in most homes and offices,
*. Plugging the fax machine into a jack which is not an RJ-11C. jack
may result in damage to the machine or your telephone system. If
you do not know what kind of jack you have, or need to have one
installed, contact the telephone company.
If the machine is moved from a cold to a warm place...
\f the machine is moved from a cold to a warm place, it is possible
that the reading glass may fog up, preventing proper scanning of
documents for transmission. To remove the fog, turn on the power
and walt approximately 2 hours before using the machine.
