CAUTION
This product is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 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.
LASER WAVE –LENGTH : 780 ~ 795
Pulse times : 0.481ms/6mm
Out put power : 0.20 ±0.03mW
CAUTION
INVISIBLE LASER RADIATION,

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.

AL-1551 UNPACKING AND INSTALLATION 5-1
[5] UNPACKING AND INSTALLATION
1. Copier installation
Improper installation may damage the copier. Please note the following
during initial installation and whenever the copier is moved.
Caution:If the copier is moved from a cool place to a warm place,
condensation may form inside the copier. Operation in this
condition will cause poor copy quality and malfunctions.
Leave the copier at room temperature for at least 2 hours before
use.
Do not install your copier in areas that are:
•damp, humid, or very dusty
•exposed to direct sunlight
•poorly ventilated
•subject to extreme temperature or humidity changes, e.g., near an air
conditioner or heater.
The copier should be installed near an accessible power outlet for easy
connection.
Be sure to connect the power cord only to a power outlet that meets the
specified voltage and current requirements.
Also make certain the outlet is properly grounded.
Be sure to allow the required space around the machine for servicing
and proper ventilation.
2. Cautions on handling
Be careful in handling the copier as follows to maintain the performance
of this copier.
Do not drop the copier, subject it to shock or strike it against any object.
Do not expose the drum cartridge to direct sunlight.
Doing so will damage the surface (green portion) of the drum cartridge,
causing poor print quality.
Store spare supplies such as drum cartridges and TD cartridges in a
dark place without removing from the package before use.
If they are exposed to direct sunlight, poor print quality may result.
Do not touch the surface (green portion) of the drum cartridge.
Doing so will damage the surface of the cartridge, causing poor print
quality.

AL-1551 UNPACKING AND INSTALLATION 5-2
3. Checking packed components and
accessories
Open the carton and check if the following components and accessories
are included.
4. Unpacking
Be sure to hold the handles on both sides of the copier to unpack the
copier and carry it to the installation location.
5. Removing protective packing materials
1) Remove pieces of tape and protective cover. Then open the original
cover and remove protective materials (a) and (b).
2) Use a coin (or suitable object) to remove the screw.
Store the screw in the paper tray because it will be used if the copier
has to be moved.
6. Installing the TD cartridge
The TD cartridge replacement required ( ) indicator will light up when
toner is needed. If copying is continued while the indicator is lit,
copies will gradually become lighter until the copier stops and the
indicator begins blinking. Replace the old TD cartridge by following the
procedure given below.
Note:
•After the copier stops, it may be possible to make a few more copies by
taking the TD cartridge out of the copier, shaking it horizontally, then
reinstalling it. If copying is not possible after this operation, replace the
TD cartridge.
•During long copy run of a dark original, the ready ( ) indicator may
blink, the indicator may light up, and the copier may stop, even
though toner cartridge is not empty. The copier will feed toner up to 2
minutes and then the ready ( ) indicator will light up. Press the print
( ) key to restart copying.
1) Ensure that the bypass tray is open and then open the side cover by
pressing the open button on the side cover.
2) Remove the CAUTION tape from the front cover and remove the two
protective pins from the fusing unit by pulling the strings upward one
at a time.
3) Push gently on both sides of the front cover to open the cover.

4) Remove the TD cartridge from the bag. Remove the protective paper.
Hold the cartridge on both sides and shake it horizontally four or five
times.
5) Hold the tab of the protective cover and pull the tab to remove the
cover.
6) Gently insert the TD cartridge until it locks in place.
7) Close the front cover and then the side cover by pressing the round
projections near the side cover open button. The indicator will go
out and the ready ( ) indicator will light up.
Note: When closing the covers, be sure to close the front cover securely
and then close the side cover. If the covers are closed in the wrong
order, the covers may be damaged.
7. Loading copy paper
Note:This copier is equipped with two paper trays. Load copy paper into
the two paper trays.
1) Raise the handle of the paper tray and pull the paper tray out until it
stops.
2) Remove the pressure plate lock. Rotate the pressure plate lock in the
direction of the arrow to remove it while pressing down the pressure
plate of the paper tray.
3) Store the pressure plate lock which has been removed in step 2 and
the screw which has been removed when unpacking in the front of
the paper tray. To store the pressure plate lock, rotate the lock to fix it
on the relevant location.
4) Adjust the paper guides on the paper tray to the copy paper width
and length.
Squeeze the lever of paper guide (A) and slide the guide to match
with the width of the paper.
Move paper guide (B) to the appropriate slot as marked on the tray.
5) Fan the copy paper and insert it into the tray. Make sure the edges go
under the corner hooks.
Note:Do not load paper above the maximum height line ( ).
Exceeding the line will cause a paper misfeed.
6) Gently push the paper tray back into the copier.
Note:After loading copy paper, to cancel the blinking "H" without
restarting copying, press the clear ( ) key. The "P" in the display
will go out and the ready ( ) indicator will light up.
