SHARP CORPORATION This document has been published to be used
for after sales service only.
The contents are subject to change without notice.

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.
CAUTION
Warning!
This product is a class A product.
If it is operated in households, offices or similar surroundings, it can produce radio interferences at other
appliances, so that the user has to take adequate countermeasures.

∗Top margin
The set value is received from the digital copier, and data are made
according to the set value.
∗Left margin
Since the paper size sensor is not set, the digital copier cannot recog-
nize the size and direction of paper which is actually inserted.
Therefore, the left margin is set according to the paper size specified in
the print data sent from the computer, and print process is performed.
If the computer does not specify the paper size, or in the case of the
custom size, the left margin is set according to the default paper size.
(7) Print reference
This machine employs the center reference system.
Since the digital copier is not provided with the tray size detection fea-
ture, formatting and center distribution are performed not by the actual
paper size but by the paper size specified by the computer.
D. Interface
E. System outline
The GDI-PWB is provided with IEEE1284 I/F on the host side, and the
16-bit bi-directional data bus I/F and UART on the machine side.
Transfer of image data with the IMC-PWB is performed with this 16-bit
bi-directional data bus. Command status information with the engine is
processed with UART.
This unit is installed to the position of PCL-PWB on the conventional
AR-235/275.
JBIG compression data sent from the host are transferred to the IMC
PWB, where the data are extracted to be VIDEO data, and sent
through the MCU PWB to the LSU.

∗Dehumidification heater switch (DH POWER)
This copier is equipped with a dehumidification heater, which prevents
dew condensation inside the copier and moisture absorption of paper
in the paper trays. If dew condensation occurs and causes moisture
absorption of paper, image quality may be deteriorated and paper mis-
feeds may occur frequently. It is recommended that the dehumidifica-
tion heater switch be left in the “ON” position in the following cases
even after the power switch is turned off.
• In a low temperature season such as winter (When a sudden tem-
perature change occurs, for example, immediately after room heat-
ing is turned on, dew condensation may occur.)
• In a high temperature and high humidity season such as summer or
rainy season (Depends on the use conditions. The reference is 60%
(humidity) or more.)
•In regions at a high temperature and a high humidity
NOTES:
• When using the dehumidification heater, do not remove the power
cord from the outlet. Doing so will stop the heater.
• If an optional 500-sheet paper feed unit or 2x500-sheet paper feed
unit is installed, the heater in the unit will also be turned on when the
dehumidification heater switch of the copier is turned on.

AR-M208 ADJUSTMENTS 7 - 1
[7] ADJUSTMENTS, SETTING
2. Copier adjustment
B. Mechanism section
(16) SPF scan position auto adjustment
[Function]
Used to adjust the SPF scan position automatically.
[Operation]
1) With the SPF or the OC cover open, place a chart of black back-
ground on the OC glass. (In the SPF standard model, the SPF
glass surface is included.)
∗Use a black chart (UKOG-0011QSZZ) or prepare a chart as shown
below.
Chart size: 310 x 470, prepared with cutting sheet No. 791 (Black) or
an equivalent one.
2) Enter SIM53-08, and press [START] button.
Outline of SIM: The optical unit is shifted to recognize the bound-
ary between the OC glass and the SPF glass cover.
With the same position as the reference, the SPF scan position is
automatically adjusted.
<Note>
• After completion of the SPF scan position auto adjustment, the SPF
lead edge adjustment must be executed. (Both surfaces)
• There must be no other sheet than the black chart on the glass sur-
face.
• Especially when in SPF scan, the center area is scanned in the main
scan direction. Be careful to prevent external light from entering the
scan area.
3) Check that the lead edge is not shifted. (Both surfaces)
(If the original lead edge adjustment has been made properly, even
when the scan position is shifted, it is followed automatically.)
4) Change the adjustment value of the SPF scan end position.
(Change the adjustment value of SIM50-6-3 from 50 to 36.)
Change the number of steps for Pin off – scan end position from
1,014 to 986.
Be sure to execute this adjustment because an image may be cut
off during FAX transmission though copying is normally performed.
5) Change the initial value of the SPF exposure adjustment (SIM46-
20) from 50 to 53.
(For the CCD exposure adjustment with SPF, use the value of the
OC adjustment value +3.)
There are suffixes of –1 SPF and –2 SPF. Change each of them.
Reason: To prevent erroneous detection by disturbing light of a fluo-
rescent lamp, etc.
Place only the black
chart on the OC glass.
For the SPF standard-provision
machine, check that the black
chart covers the SPF glass.
Placing the black chart
The black chart must cover
this area.

When [OK] or [START] key is pressed, a caution buzzer sounds.
(Only the adjustment value can be entered.)
The minimum increment is 2V.
The result of (Set value – 199) / 2 is stored in the EEPROM.
When reading a value from the EEPROM, the value of (EEP value *2)
+ 200 is used as the set value.
Therefore, the set value entered must be an even number. If an odd
number is entered the entered odd number + 1 is displayed after
pressing [OK] key.

The input value is in the increment of –25V.
(∗) Linked with the destinations of SIM 26-6.
Linked with the auto exposure mode of SIM 46-19-1.
*SUPER PHOTO (5:) cannot be executed.
When [OK] or [START] key is pressed, a caution buzzer sounds.
(Only the adjustment value can be entered.)
*1. The negative value of the set value corresponds to the grid high
output voltage.
*2. The set values can be selected from the above 8 patterns only.
*3. The selected pattern determines the grid high voltage and the grid
low voltage.
If, for example, the grid high voltage is set to –480V (pattern 1), the
grid low voltage is –350V.
Operation/procedure
After selecting the mode, enter the adjustment value and press the
[OK] key, and output will be made for 30sec.
The minimum increment is 2V.
The result of (Set value – 199) / 2 is stored in the EEPROM.
When reading a value from the EEPROM, the value of (EEP value *2)
+ 200 is used as the set value.
Therefore, the set value entered must be an even number. If an odd
number is entered the entered odd number + 1 is displayed after
pressing [OK] key.
Operation/procedure
After selecting the mode, enter the adjustment value and press the
[OK] key, and output will be made for 30sec.
The input value is in the increment of –25V.

Operation/procedure
The misfeed history is displayed in the sequence of recentness by the
name of sensors and detectors. Max. 40 items of information can be
stored in memory. (The old ones are deleted sequentially.) The trouble
section may be determined by the data.
*1. Not reached, double fed and the next paper reached the paper-in
sensor.
*2. Detects that paper from 3rd (4th) stage enters 2nd stage.
*3. Detects that paper from 4th stage enters 3rd stage.
*4. The passing time over P-IN sensor (manual feed P-IN sensor) of
the front surface differs greatly from that of the back surface.
*5. Occurs when not reached either of FIN_ESC sensor and
FIN_P_OFSET sensor.
