CAUTION
This laser facsimile is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH or IEC60825-1 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 cover 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.
Laser Wave Length : 780 ±15 nm
Laser Pulse Times : (13.95 ± 3 µs)/7mm
Laser Output Power : 0.4 mW ± 0.05mW
Parts marked with " " is important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.

[4] Installation
2. Installing the toner cartridges
1. Site selection
The laser printer in your fax machine uses a toner cartridge and a
drum cartridge. The drum cartridge comes pre-installed, and the
toner cartridge must be installed.
Take the following points into consideration when selecting a site for this
model.
ENVIRONMENT
•
•
The machine must be installed on a level surface.
•
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 starter toner cartridge
included with your fax can
print approximately 1,875
letter-size pages st 4%
page coverage
Keep the machine away from air conditioners, heaters, direct sunlight, and dust.
When replacing the toner
cartridge, use a Sharp
UX-400ND toner cartridge.
One cartridge can print about
3,750 letter-size pages.
• The drum cartridge can print approximately 20,000 letter-size
pages. When replacing the drum cartridge, use a Sharp
UX-400DR drum cartridge.
The temperature should be between 10° and 30°C (50° and 86°F).
The humidity should be between 20% and 85% (without condensation).
Follow the steps below to install the toner cartridge and prepare the
drum cartridge.
ELECTRICITY
AC 120 V, 60 Hz, grounded (3-prong) AC outlet is required.
1
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
speciality stores
Grasp the print compartment cover at both sides as shown, and
pull up to open the cover.
• Caution! The fusing unit inside the print compartment becomes
very hot during operation. Do not touch the inside of the
compartment or the paper guide on the underside of the print
compartment cover.
TELEPHONE SOCKET
A standard RJ11C telephone socket must be located near the machine.
This is the telephone socket commonly used in most homes and offices.
• Plugging the fax machine into a socket which is not an RJ11C socket
may result in damage to the machine or your telephone system. If
you do not know what kind of socket you have, or need to have one
installed, contact the telephone company.
If the machine is moved from a cold to a warm place...
If 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 wait approximately 2 hours before using the machine.
