CAUTION
This product is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH stand-
ard 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 haz-
ardous 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 : 0.481 ms/6 mm

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

4. Memory Device
A. Function
The memory device is used to monitor the life of the developer cartridge in the way that the machine reads and writes information (e.g.page count)
to the memory device equipped in the developer cartridge.
When the life is reached, the memory device becomes nonfunctional to prevent the deterioration of image/text quality and machine damages.
Therefore, unnecessary service costs would be saved.

5) Tilt the DV box unit and rotate the DV18T clockwise to remove
developer.
6) Clean the DV box unit by sucking or blowing with a vacuum cleaner
to remove developer from the MG roller and toner from the DV box
unit. Check that there is no toner or no foreign material attached to
the connector and the gear.
7) Shake the developer bottle 10 times up and down, and remove the
bottle cap and supply developer into the DV box unit.
•Slowly slant the bottle to supply developer evenly.
•Check the label to insure that developer is suitable for the model.
8) Install the THBOX unit.
•Insert two bosses of TH box on the drive side into the positioning
hole of the DV box and fix together.
9) Remove the toner cap, look into the toner supply port and stop the
THD Mylar at the position shown in the figure below. (Rotate the
THK gear on the rear side of the TH box counterclockwise to rotate
the TM shaft.)
10) Shake the toner box 20 times up and down, and remove the bottle
cap and install the refill hose. Check the label to insure that toner
is suitable for the model.
11) Face the toner supply port of the TH box unit upward, and press
and insert the refill hose into the toner supply port with the toner
bottle kept straight up.
•Hold the left side of the TH box with your hand.
•Press and insert the refill hose completely.
12) Lift the toner bottle and shake it left and right and supply toner
until the bottle and the filling hose are empty.
•It takes about one minute to fill toner completely in TH BOX UN
from lifting the toner bottle to emptying the bottle and the hose.
•If toner remains in the hose, when removing the hose from TH
BOX UN, the remaining toner may disperse. Use great care for
that.
13) Check that there is no toner remaining in the bottle and remove
the hose, and slowly pull and remove the hose.
(If there is any toner remaining in the bottle or the hose, perform
toner supply again.)
Bend the refill hose and remove it from the TH box unit without
dispersing toner. Attach the toner cap.
•Attach the toner cap with the toner supply port of the TH box unit
faced upward.

14) Clean the DV box unit with alcohol and attach the DV blade.
•After drying the unit, attach the DV blade.
•After attachment, check that there is no scratch and waves on
the DV blade.
•After attachment, be careful not to damage the DV blade.
•Check that there is no foreign material in the DV blade and the
section.
15) Install the DVF cover to the DV-TH box unit.
16) Clean the waste toner box unit and install it to the DV box unit.
(Check that there is no toner in the waste toner box)
Be careful of the pawl.
17) Replace the IC connector.
Check that there is no oil on the IC connector pins. (Do not touch
with fingers.)
Put a white mark on the above position.
At that time, put marking for checking of the number of refilling.
18) Check the operations of the DV lever and the toner box shutter.
19) Shake the DV box unit 5 times horizontally. Rotate the DV18T
clockwise and check developer state on the MG roller. (Visually
check that developer state is normal and there is no foreign
material.)
20) Install the MG cover.
Put the unit straight with the MG roller on the upper side. Rotate
the DV18T several times forward and reverse to store developer
on the MG roller into the inside. Check that there is no developer
on the MG roller surface, and install the MG cover.
Note: When attaching the MG cover, be careful not to wind around
the DV blade.
Note for MG cover installation
•When installing, check that there is no breakage and peel-off of
the MG cover sheet and the MG cover molt attached to the MG
cover.
•Check that there is no winding into the DV blade, deformation
and scratches of DV molt F and R.
