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.

CHAPTER 2. ADJUSTMENTS
[1] Adjustments
General
Since the following adjustments and settings are provided for this
model, make adjustments and/or setup as necessary.
1. Adjustments
Adjustments of output voltage (FACTORY ONLY)
1. Install the power supply unit in the machine.
2. Set the recording paper and document.
3. When the document is loaded, power is supplied to the output
lines. Confirm that outputs are within the limits below.

2.1C protectors replacement
ICPs (IC Protectors) are installed to protect the TX motor drive circuit,
printer motor drive circuit and the PCU drive circuit. ICPs protect
various ICs and electronic circuits from an overcurrent condition.

ICP301 (ICP-N25) is installed in order to protect 1C’s from and
overcurrent generated in the PCU drive circuit and printer motor
drive circuit. If ICP301 is open, repiace it with a new one.
FU1 (ICP-N20) is installed in order to protect IC's from an over-
current generated in the TX motor drive circuit. If FU1 is open,
replace it with a new one. . Fae
In addition to the replacement of ICP301 and FU1, the factor
causing |CP301 and FU1 to open must also be repaired. {f not,

Rapid key 01: Soft switch setting mode
Used to change the soft switch settings.
The soft switch which is stored internally is set by using the keys.
The available soft switches are SW1 to SW28. (TH/GU)
The available soft switches are SW1 to SW29. (SG/GH)
The content of soft switches is shown in page 2-8 to 2-13.
Atter setting SW28 (TH/GU), press the "1" key, and the soft switch
table list will be printed.
Atter setting SW29 (SG/GH), press the "1" key, and the soft switch
table list will be printed.
Hera, the content of the soft switch will be backed up.
Rapid key 02: Not used
Rapid key 03: ROM & RAM check mode
This mode is provided to check the states of ROM, SRAM and DRAM
of the main PWB.
This mode have three check modes as following:
@® All device is tested
@® ROM device (main CPU's ROM & sub CPU's ROM) are tested
@ RAM device (SRAM & DRAM) are tested
ROM executes the sum check, and RAM executes the matching test.
The result will be notified with the number of short sounds of the
buzzer as weil as by printing the ROM & RAM check list.
Number of short sounds of buzzer 0 — No error
1 Main ROM error
2 ~ Sub ROM error
3 — Main SRAM error
4 > Main DRAM error
5 — Sub RAM error
After finishing test, the following will be printed.
