CAUTION
This product is a class 1 laser product that complies with 21CFR 1040 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

2. Note for servicing and handling
When the main unit power is repeatedly turned OFF/ON rapidly (for about 1sec), the IC (OA982) on the MCU PWB may malfunction to cause an error
(E1-00 Communication error), which does not boot the machine. In case of this error, the blank display is kept for several tens seconds and then "E100" is displayed on the panel display.
<Countermeasure>
Turn off the power and keep it for more than 10sec. Then turn on the power.
When the machine is booted.: There is no problem in the MCU PWB.
When the machine is not booted.: The MCU PWB trouble

2. Outline of print process
Step-2: Exposure (laser beam, lens)
This printer is a non-impact printer that uses a semiconductor laser
and electrostatic print process. This printer uses an OPC (Organic
Photo Conductor) for its photoconductive material.
First, voltage from the main corona unit charges the drum surface and
a latent image is formed on the drum surface using a laser beam. This
latent image forms a visible image on the drum surface when toner is
applied. The toner image is then transferred onto the print paper by the
transfer corona and fused on the print paper in the fusing section with
a combination of heat and pressure.
Step-1: Charge
Step-2: Exposure
* Latent image is formed on the drum.
Step-3: Developing
Latent image formed on the drum is then changed into visible
image with toner.
Step-4: Transfer
The visible image (toner image) on the drum is transferred
onto the print paper.
Step-5: Cleaning
Residual toner on the drum surface is removed and collected
by the cleaning blade.
Step-6: Optical discharge
Residual charge on the drum surface is removed, by
semiconductor laser beam.
3. Actual print process
A Laser beam is generated from the semiconductor laser and
controlled by the print pattern signal. The laser writes onto the OPC
drum surface through the polygon mirrors and lens. The resistance of
the OPC layer decreases for an area exposed by the laser beam
(corresponding to the print pattern signal). The beam neutralizes the
negative charge. An electrostatic latent image is formed on the drum
surface.

Step-3: Developing (DC bias)
Step-4: Transfer
A bias potential is applied to the MG roller in the two component
magnetic brush developing method, and the toner is charged negative
through friction with the carrier.
Non-image area of the drum surface charged with negative potential
repel the toner, whereas the laser exposed portions where no negative
charges exist, attract the toner. As a result, a visible image appears on
the drum surface.
The visible image on the drum surface is transferred onto the print
paper by applying a positive charge from the transfer corona to the
backside of the print paper.

Step-5: Separation
Since the print paper is charged positively by the transfer corona, it is
discharged by the separation corona. The separation corona is
connected to ground.
Step-6: Cleaning
Toner remaining on the drum is removed and collected by the cleaning
blade. It is transported to the waste toner collecting section in the
cleaning unit by the waste toner transport roller.
Toner is attracted over the shadowed area because of the developing
bias.
AR-168S/168D COPY PROCESS 6 - 3
Step-7: Optical discharge (Semiconductor laser)
Start
Before the drum rotation is stopped, the semiconductor laser is
radiated onto the drum to reduce the electrical resistance in the OPC
layer and eliminate residual charge, providing a uniform state to the
drum surface for the next page to be printed.
When the electrical resistance is reduced, positive charges on the
aluminum layer are moved and neutralized with negative charges on
the OPC layer.
1) Because the grid potential is at a low level, the drum potential is at
about -400V. (Carrier may not be attracted though the carrier is
pulled towards the drum by the electrostatic force of -400V.
2) Developing bias (-400V) is applied when the photoconductor
potential is switched from LOW to HIGH.
3) Once developing bias (-400V) is applied and the photo conductor
potential rises to HIGH, toner will not be attracted to the drum.
Semiconductor laser
Stop
The reverse sequence takes place.
Retaining developing bias at an abnormal occurrence
Function
The developing bias will be lost if the power supply was removed
during print process. In this event, the drum potential slightly abates
and the carrier makes deposits on the drum because of strong static
power. To prevent this, the machine incorporates a function to retain
the developing bias for a certain period and decrease the voltage
gradually against possible power loss.
Charge by the Scorotron charger
Function
The Scorotron charger functions to maintain uniform surface potential
on the drum at all times, It control the surface potential regardless of
the charge characteristics of the photoconductor.
Basic function
A screen grid is placed between the saw tooth and the
photoconductor. A stable voltage is added to the screen grid to
maintain the corona current on the photoconductor.
As the photoconductor is charged by the saw tooth from the main
corona unit, the surface potential increases. This increases the current
flowing through the screen grid. When the photoconductor potential
nears the grid potential, the current turns to flow to the grid so that the
photoconductor potential can be maintained at a stable level.
Basic function
Normally, the developing bias voltage is retained for a certain time
before the drum comes to a complete stop if the machine should stop
before completing the normal print cycle. The developing bias can be
added before resuming the operation after an abnormal interruption.
Therefore, carrier will not make a deposit on the drum surface.
Process controlling
Function
The print pattern signal is converted into an invisible image by the
semiconductor laser using negative to positive (reversible) developing
method. Therefore, if the developing bias is added before the drum is
charged, toner is attracted onto the drum. If the developing bias is not
added when the drum is charged, the carrier is attracted to the drum
because of the strong electrostatic force of the drum.
To avoid this, the process is controlled by adjusting the drum potential
and the grid potential of the Scorotron charger.
Basic function
Voltage added to the screen grid can be selected, high and low. To
make it easily understood, the figure below shows voltage transition at

Fusing resistor
Heat roller
This model is provided with a fusing resistor in the fusing section to
improve transfer efficiency.
Since the upper heat roller is conductive, when using copy paper that
contains moisture and the distance between the transfer unit and the
fusing unit is short, the transfer current may find a path to ground via
the copy paper, the upper heat roller and the discharging brush.

Paper feed is made in two ways; the tray paper feed and the manual
paper feed. The tray is of universal-type, and has the capacity of 250
sheets.
The front loading system allows you to install or remove the tray from
the front cabinet.
The general descriptions on the tray paper feed and the manual paper
feed operation are given below.
Level of the thermistor is
controlled by the main PWB.
With the signal from the
main PWB, the triac is
controlled on and off.

AR-168S/168D OPERATIONAL DESCRIPTIONS 7 - 4
(1) Cassette paper feed operation
1) The figure below shows the positions of the pick-up roller, the
paper feed clutch sleeve, and the paper feed latch in the initial
state without pressing the COPY button after lighting the ready
lamp.
The paper feed latch is in contact with the projection of the clutch
sleeve.
2) When the COPY button is pressed, the main drive motor starts
rotating to drive each drive gear.
The pick-up drive gear also is driven at that time. Since, however,
the paper feed latch is in contact with the projection of the clutch
sleeve, rotation of the drive gear is not transmitted to the pick-up
roller, which does not rotate therefore.
PFS
OFF
5) At this time, the paper is fed passed the paper entry detection
switch (PPD1), and detected by it. After about 0.15 sec from
detection of paper by PPD1, the tray paper feed solenoid (PFS)
turns on so that the clutch sleeve projection comes into contact
with the paper feed latch to stop the pick-up roller. Then the pickup roller rotates for about 0.15 sec so that the lead edge of the
paper is evenly pressed on the resist roller, preventing against
skew feeding.
PFS
ON
OFF
6) To release the resist roller, the tray paper feed solenoid and the
resist solenoid are turned on by the paper start signal to disengage
the resist start latch from the clutch sleeve, transmitting rotation of
the resist drive gear to the resist roller shaft. Thus the paper is
transported by the resist roller.
7) After the resist roller starts rotating, the paper is passed through
the pre-transfer guide to the transfer section. Images are
transferred on the paper, which is separated from the OPC drum
by the drum curve and the separation section.

3) After about 0.1 sec from when the main motor start rotating, the
tray paper feed solenoid (PFS) turns on for a moment.
This disengages the paper feed latch from the projection of the
clutch sleeve, transmitting rotation of the pick-up drive gear to the
paper feed roller shaft, rotating the pick-up roller to feed the paper.

8) The paper separated from the drum is passed through the fusing

detector) to the copy tray.
4) After more than half rotation of the pick-up roller, the paper feed
latch is brought in contact with a notch on the clutch sleeve,
stopping rotation of the pick-up roller.

(2) Manual multi paper feed operation
1) Before paper feed operation, the manual paper feed solenoid
(MPFS) is turned OFF as shown in the figure below.

A from the manual paper feed clutch sleeve A, rotating the manual
paper feed roller and the manual take-up roller. At the same time,
the manual paper feed stopper opens and the manual take-up
roller is pressed to the surface of the paper to start paper feeding.
4) The lead edge of the transported paper is pressed on the resist
roller by the transport roller. Then the paper is stopped temporarily
to allow synchronization with the lead edge of the image on the
OPC drum.
From this point, the operation is the same as the paper feed
operation from the tray. (Refer to A-5 - 8.)
5) The solenoid turns off to close the gate and return to the initial
state.

3. High voltage adjustment
4. Duplex adjustment
A. Main charger (Grid bias)
A. Adjusting the paper reverse position in memory
for duplex copying
Note:
• Use a digital multi meter with internal resistance of 10MΩ or more
measurement.
• After adjusting the grid LOW output, adjust the HIGH output. Do not
reverse the sequence.
Procedures
1) Set the digital multi meter range to DC700V.
2) Set the positive side of the test rod to the connector CN11-3
(GRID) of high voltage section of the power PWB and set the
negative side to the frame ground (power frame).
3) Execute TC 8-02. (The main charger output is supplied for 30 sec
in the grid voltage HIGH output mode.)
4) Adjust the control volume (VRG1) so that the output voltage is 580
±12V.
This step adjusts the front surface printing (odd-number pages of a
document set) in the S-D mode copying and the leading edge position
of an image on even-number pages in the D-S mode.
That is, it covers the adjustment of the second surface printing mode
(image loss at the front edge of an image) in which image data is once
stored in memory.
The image data is read, starting from its front end in the document
delivery direction (Reference direction of document setting in the OC
mode)and stored in memory.
This stored image data is printed starting at the printing start position,
in the order of last-stored data to the first-stored data.
In other words, the front edge image loss of the image can be adjusted
by changing the document read end position.
(Adjustment procedure)
1) Preparing test chart (Draw a scale at the rear end of one side of a
sheet of A4 white paper or letter paper)
5 10
VRG1
2) Set the test chart so that the scale is positioned as shown below, in
the S-D mode and the D-S mode.

B. DV bias check
Note: • A digital multi meter with internal resistance of 1GΩ must be
use for correct check.
• The adjustment volume is locked, and no adjustment can be
made.
Procedures
3) Execute test command 50-18.
1) Set the digital multi meter range to DC500V.
2) Set the positive side of the test rod to the connector CN-10-1 (DV
BIAS) and set the negative side to the frame ground (power
frame).
3) Execute TC 25-01 to output the developing bias for 30sec, and
check that the output is –400±8V.

B. Adjusting trailing edge void in duplex copy mode
This is the adjustment of the first surface printing mode (rear end void)
in duplex copying.
In a duplex copying operation, the paper is delivered starting from the
rear end of the first printing surface. It is therefore necessary to make a
void area at the rear end on the first printing surface to prevent paper
jam at the fusing part.
3) Execute test command 50-19 to turn on the PRINT mode lamp and
make the printing mode in OC-D mode.
Make a copy of the test chart to check the void area of the scale on
the image.
Void position to be check
There are two adjustment modes:
1) Image cut rear end void quantity (R-SPF) 50-19 (SCAN mode
lamp)
The size (length) of a document read from the R-SPF is detected,
the image at the trailing edge of the first printing surface is cut to
make a void area. (The adjustment of void quantity at the time
when the cassette paper size is not recognized.)
Paper
2) Paper trailing edge void quantity 50-19 (PRINT mode lamp)
This adjustment is made when the cassette paper size is
recognized. The trailing edge void quantity can be adjusted by
changing the trailing edge image laser OFF timing.
The paper void quantity should be first adjusted before the image cut
trailing edge void quantity (R-SPF) is adjusted.
The adjustment modes can be selected by pressing [←/→] key.
(Adjustment range; 1 – 99)
Enter the adjustment value and press [START] key to save the set
value and make a copy. (The paper information is cleared for every
copy.)
When the set value is increased by 1, the void amount is increased by
about 0.1mm.

5. SPF (RSPF) scan position automatic
adjustment
The size of the black chart (UKOG-0011QSZZ) is 297 x 420. Divide it
into four for use.
Place a black chart so that it covers the SPF scan glass and the OC
glass together, and close the OC cover.
When test command 53-08 is executed, the current adjustment value
is displayed as the initial display.
* Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 = about
0.127mm
* If the values are kept as the default values, SPF scan is not performed properly. The front area of the proper scan position may be
scanned.
In case of AUTO, press [START] key, and the mirror unit scans from
the home position to the SPF scan position with the adjustment value
displayed. The SPF glass cover edge position is calculated from the
difference between the SPFG glass cover edge and the OC side
document glass CCD output level. If the adjustment is normal, the
adjusted value is displayed. If abnormal, the error LED lights up with
the current set value displayed.

[Adjustment procedure]
1) Set the print start position (A: COPY mode lamp ON), the lead edge void amount (B: PRINT mode
lamp ON), the scan start position (C: SCAN mode lamp) to zero, and make a copy of the scale at
100%.
2) Measure the image loss (Rmm) of the scale.
Set C = 10 x R (mm). (Example: Set to 40.)
When the value of C is increased by 10, the image loss is decreased by 1mm. (Default: 50)
3) Measure the distance (Hmm) from the paper lead edge to the image print start position.
Set A = 10 x H (mm). (Example: Set to 50.)
When the value of A is increased by 10, the image lead edge is moved to the paper lead edge by
1mm. (Default: 50).
4) Set the lead edge void amount to B = 50 (2.5mm). (Default: 50)
When the value of B is increased by 10, the void is extended by about 0.1mm. (For 25 or less,
however, the void amount is regarded as 0.)
∗ The SFP adjustment is made by adjusting the SPF image scan start position after OC adjustment.
∗ When paper is discharged, the shifter is operated.

For S-D mode front surface print and print of even paged in D-S mode, reverse memory copy operation is performed from the rear edge of documents.
When, therefore, the print position adjustment of output images is required, adjust as follows:
In the reverse memory coping, when the document scan is made in the arrow direction, the output
image is printed from the rear edge of scan image,
When, therefore, the print lead edge is shifted, set the reference chart so that the reference position is
on the rear edge, and use this test command to adjust the set value so that the print lead edge is
matched.
Since printing is made from the image data most lately stored in memory to the lead edge data from
the print start position, the image lead edge adjustment is made by changing the end data position
stored in memory by the set value of this test command.
Since it is performed by changing the scan end position, the image position adjustment is made by

This circuit detects ON/OFF of the power source, and controls start/
stop of each circuit. The voltage of 3.3V in the MCU PWB is detected
by the reset IC to generate the reset signal.
When the power voltage reaches the specified level, each circuit is
operated, but stopped before the power voltage falls below the specified level in order to protect against malfunction of the circuit. The
CPU/Flash ROM is reset by the power reset circuit, and system reset
of ASIC, OA982, FAX, and NIC is generated from the CPU (generalpurpose port output).

The CPU converts the inputted analog voltage into a digital value. The
digital conversion value and the set value of the test command are
compared to control ON/OFF of the heater lamp according to the level,
controlling the heat roller surface temperature to be the fixed level.

HLOUT (10-B3)
[High temperature protection circuit in case of CPU hung up
(uncontrollable)]
For IC22 3Pin (reference voltage), +3.3V is divided by the resistor. The
thermistor terminal voltage is inputted to IC22 2Pin. When, therefore,
the voltage at 2Pin falls below the voltage at 3Pin, IC22 1Pin becomes
"H" and the HL signal is pulled to the GND level, suppressing generation of the lighting signal of the heater lamp. (IC22 output 1Pin is normally Low.)
[When the heat roller surface temperature is lower than the set
level]
a. When the thermistor terminal voltage is higher than the set level,
the output signal HL from ASIC becomes HIGH level.
b. This HL signal becomes the HLOUT signal through IC26, and is
inputted to the photo triac coupler in the power PWB. When, therefore, the HL signal is HIGH, the internal triac turns on.
[When the thermistor is open]
The voltage at IC22 6Pin becomes higher than the voltage at 5Pin, and
the 7Pin output THOPEN becomes LOW. This is inputted to the CPU
to display the trouble code H2.
(6) Driver circuit (Clutch, solenoid)
Since a load cannot be directly driven by each load signal from the
CPU or the ASIC, each load is driven through the driver IC (transistor
array).
A large drive current (load current) is ordained from a small input current (ASIC output current).
When the driver input voltage (base resistor input) is HIGH, the transistor turns ON to flow a current through the load, operating the load.

(11) Carriage Unit
a. Outline
a. Outline
The operation circuit is composed of the LCD control circuit, the key
matrix circuit, the display matrix circuit, and the buzzer circuit, realizing
the U/I functions.
The carriage unit is provided with the CCD PWB, the inverter PWB, the
lamps, etc. A document is radiated, and image data read by the CCD
are A/D converted to be sent to the ASIC.
b. LCD control circuit
b. CCD PWB
The character LCD (COG) in 2 lines and 16 digits is used. The display
data are sent from the MCU (CPU) to LCD internal registers, controlling the LCD.
The color image sensor uPD8861 (5400 pixels x 3 lines) is used as the
CCD on the CCD PWB to scan images in the resolution of 600dpi/US
letter size in the main scanning direction.
c. Key matrix circuit
The SEL signal is sent from the CPU of MCU to the matrix selector IC
(multiplexer) in the operation circuit. The signal detects OFF/ON of the
key, and is sent to the CPU as serial data.
Image data scanned by the CCD are inputted to AFE (AD9826), where
they are A/D-converted to output digital data. The output digital data
are sent to the MCU PWB and to the ASIC. The ASIC performs image
process with the digital data.
d. LED matrix circuit
c. Lamp inverter PWB
The display is controlled by inputting the serial data signal, the clock
signal, and the latch signal from ASIC to the LED driver in the operation circuit.
The transformer is controlled by the lamp control signal from the MCU
PWB to turn ON/OFF the cool cathode ray tube by the transformer output.
In the LED driver, data are set to the register (8bit) and latched to control the IC output port, performing matrix-driving of ON/OFF of the LED.
B. DC power circuit
The DC power circuit directly rectifies the AC power and performs
switching-conversion with the DC/DC converter circuit, and rectifies
and smoothes again to generate a DC voltage.
The constant voltage control circuit is of +5VEN. +24V and +12V are of
the non-control system by winding from the +5VEN winding. As shown
in fig (1), +24V, +12V, and +5V are provided with the ON/OFF function
by external signals. +3.3V is outputted from +5VEN to the regulator IC.
Refer to the block diagram, fig (1).

(1) Noise filter circuit
The filter circuit is composed of L and C. It reduces common noises
and normal mode noises generated from the AC line.
(2) Rush current prevention circuit and rectifying/
smoothing circuit
The common noise means that generated in each line for GND. Its
noise component is delivered through C002, C003, and C022 to GND.
The normal noise means that overlapped in the AC line or the output
line. It is attenuated by C023, C001, L002, C004, and L003. Refer to fig
(2).

AR-168S/168D ELECTRICAL SECTION 13 - 11
Since the AC power is directly rectified, if there were not this rush current prevention resistor (TH001), an extremely large rush current
would flow due to a charging current flowing through the smoothing
capacitor C006 when turning on the power.
To prevent against this, the rush current prevention resistor TH001 is
provided between the rectifying diode D003 and the smoothing diode
C006, suppressing a rush current.

When Q001 turns off, energy accumulated in the transformer (T001)
flows a current of waveform C in the path indicated with dotted line as
shown in the figure above through D101 and D113 and dissipates to
the secondary output side. When this energy is exhausted, the current
flowing through D101 and D113 turns off. However, the NS winding has
a slight remaining energy, which generates a voltage in the base winding NC and turns on Q001 again to repeat switching operation, supplying a high frequency power to the secondary side.
(4) Overcurrent protection circuit (Primary side)
The ON period extension due to an increased output load is detected,
and the OFF period of Q001 is extended by the control circuit, and
energy accumulated in the primary winding of the transformer T001 is
reduced, providing protection against an overcurrent. Refer to Fig. (4).
(5) Rectifying/smoothing circuit (+5V)
Fig. (4) Inverter and control circuit
When the power is supplied to this circuit, the DC voltage, Vref, supplied by the rectifying/smoothing circuit is applied through R006 and
R007 to FET (Q001), turning on Q001.
When Q001 is turned on, the drain current, ID, flows as the waveform B
in Fig. (5) to apply VDC to the main winding, NP, on the primary side.
At the same time, a voltage is generated in NC winding and applied
through R005 and C008b to the gate of Q001. As a result, Q001 is
turned on rapidly.
At the same time with this, C009 is charged through D001, R001, and
D012. When the potential of C009 reaches 0.7V (= VBE of Q002), Q002
turns on to turn off Q001.
fig (6) Rectifying/smoothing circuit
The high frequency pulse generated by the inverter circuit is
decreased by the converter transformer, rectified by the high frequency
diode D113, and smoothed by C107 and C108.

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread.
Never use conventional lead solder thread, which may cause a breakdown or an accident.
Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use
soldering iron is recommendable.
(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering capacity is
inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land separation or may exceed
the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when completion of soldering is
confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip after
completion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
