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 : 0.481 ms/6 mm
Out put power : 0.20 ± 0.03 mW

CAUTION

INVISIBLE LASER RADIATION,
WHEN OPEN AND INTERLOCKS DEFEATED.
AVOID EXPOSURE TO BEAM.

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.

Caution

This product contains a low power laser
device. To ensure continued safety do not
remove any cover or attempt to gain access
to the inside of the product. Refer all
servicing to qualified personnel.

The foregoing is applicable only to the 220V
model

230V model and 240V model.

8. Connecting the Telephone Line Cord

Plug one end of the telephone line cord into the jack on the unit
marked “LINE” .Plug the other side into a standard (RJ11C)
single-line telephone wall jack. Be sure not to plug this line cord
into the “TEL” jack. The “TEL” jack is used to attach an exten­sion telephone or answering machine to the unit. (See “Con-
necting Other Devices” in this chapter for details.)

Note: If your area experiences a high incidence of lightning or

power surges, we recommend that you install surge
protectors for the power and telephone lines. Surge
protectors can be purchased from your dealer or at most
telephone specialty stores.

TEL

LINE

● You can connect an extension phone to the unit to make and
receive calls like any other extension phone on your line.
Even if you pick up the extension phone and hear a fax tone,
the unit will automatically cut in and take over the line. Note,
however, that if you also have a PC modem on the same
line, you must turn on the Remote Reception function, and
deactivate the Fax Signal Receive function. See “Setting Up
the Unit for Use with a PC Modem” and “Using the Remote
Reception Function” in Chapter 2).

Note: The Remote Reception function is initially set to “ON”.

10. POWER TO COPIER

1) Ensure that the power switch of the copier is in the OFF

position. Insert the attached power cord into the power cord
socket at the rear of the copier.

2) Plug the other end of the power cord into the nearest outlet.

9. Connecting Other Devices

If desired, an answering machine or external telephone can be
connected to the unit through the telephone jack, labeled “TEL”,
on the rear of the unit.

● Connecting an answering machine to the unit allows you to
receive both voice and fax messages when you are out. To
use this feature, first change the outgoing message of your
answering machine, and then set the reception mode of the
unit to “A.M”. (Answering Machine mode) when you go out.

Note: If you are using distinctive ringing with an answering

machine, you do not need to follow the procedure
described below. (Please note that when distinctive ring­ing is used, the answering machine must be connected
to a separate wall jack, not to your fax.)

The outgoing message of your answering machine should be
changed to inform callers who want to send a fax to press their
FAX START key.

Comments:

1) It is advisable to keep the length of the message under 10

seconds. If it is too long, you may have difficulty receiving
faxes sent by automatic dialing.

2) Your callers can even leave a voice message and send a

fax message on the same call. Modify your outgoing mes­sage to explain that this can be done by pressing their FAX
START key after leaving their voice message.

Setting conditions

1) Set copy conditions such as the copy quantity and the copy density with the operation section, and press the COPY button. The information
on copy conditions is sent to the MCU.

Image scanning

2) When the COPY button is pressed, the scanner section starts scanning of images.
The light from the copy lamp is reflected by the document and passed through the lens to the CCD.

Photo signal/Electric signal conversion

3) The image is converted into electrical signals by the CCD circuit and passed to the MCU.

Image process

4) The document image signal sent from the CCD circuit is processed under the revised conditions and sent to the LSU (laser unit) as print data.

Electric signal/Photo signal (laser beam) conversion

5) The LSU emits laser beams according to the print data.
(Electrical signals are converted into photo signals.)

6) The laser beams are radiated through the polygon mirror and various lenses to the OPC drum.

Printing

7) Electrostatic latent images are formed on the OPC drum according to the laser beams, and the latent images are developed to be visible im­ages (toner images).

8) Meanwhile the paper is fed to the image transfer section in synchronization with the image lead edge.

9) After the transfer of toner images onto the paper, the toner images are fused to the paper by the fusing section. The copied paper is discharged
onto the exit tray.

2. Scanner section

A. How to scan documents

The scanner has sensors that are arranged in a line. These sensors scan a
certain area of a document at a time and deliver outputs sequentially. When
the line is finished, the next line is scanned, and this procedure is repeated.
The figure below shows the case where the latter two sections of an image
which are scanned are shown with solid lines and the former two sections
which are being transmitted are shown with dotted lines.
The direction of this line is called “main scanning direction,” and the scanning
direction “sub scanning direction.”
In the figure above, one line is divided into 4 sections. Actually, however, one
line is divided into thousands of sections. For scanning, the light receiving ele­ment called CCD is used.
The basic resolution indicates the scanner capacity. The basic resolution is ex­pressed in dpi (dot/inch) which shows the number of light emitting elements per
inch on the document.
The basic resolution of this machine is 400dpi.
In the sub scanning direction, at the same time, the motor that drives the op­tical system is controlled to scan the image at the basic resolution.

10 Mirror motor 11 MHPS (Mirror home position sensor)

The scanner unit performs scanning in the digital optical system.
The light from the light source (Xenon lamp) is reflected by a document and passed through three mirrors and reduction lenses to the CCD element
(image sensor) where images are formed. This system is known as the reduction image sensor system. Photo energy on the CCD element is con­verted into electrical signals (analog signals). (Photo-electric conversion). The output signals (analog signals) are converted into digital signals (A/D
conversion) and passed to the MCU (main control/image process section). The resolution at that time is 400dpi.
The mirror unit in the scanner section is driven by the mirror motor.
The MHPS is provided to detect the home position of the copy lamp unit.

3. Laser unit

The image data sent from the MCU (image process circuit) is sent to
the LSU (laser unit), where it is converted into laser beams.

A. Basic structure

The LSU unit is the writing section of the digital optical system.
The semiconductor laser is used as the light source, and images are
formed on the OPC drum by the polygon mirror and fθ lens, etc.
The laser beams are passed through the collimator lens, the cylindrical
lens, the polygon mirror, the fθ lens, and the mirror to form images on
the OPC drum in the main scanning direction. The laser emitting PWB
is provided with the APC (auto power control) in order to eliminate fluc­tuations in the laser power. The BF PWB works for measurement of the
laser writing start point.

(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.

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 pick-up 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.

3) After about 0.1 sec from when the main motor start rotating, the
tray paper feed solenoid (PFS) turns on at 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.

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 projection, 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.

4) After more than half rotation of the pick-up roller, the paper feed
latch is brought in contact with the projection of the clutch sleeve,

paper/document transport (AR-155 only)

A. Initial state

Set duplex documents on the document tray.
Set paper on the cassette. (In the duplex mode, the manual feed tray
cannot be selected.)

B. Front copy

Document transport: The document feed roller feeds the document

from the paper feed roller to the PS roller.
→ The document is exposed in the exposure

section, and sent to the document exit section
by the transport/paper exit roller.

→ R-SPF gate solenoid ON
→ The document is sent to the intermediate tray

(but not discharged completely.)

→ The document is stopped once, then

switchback operation is performed. (To the
back copy)

Paper transport: The document is passed through the paper feed

roller and the PS roller by the paper feed roller
and the images on the front surface are trans­ferred.
→ The paper is passed through the fusing sec-

tion and the lower side of the gate section to
the paper exit tray side, (but not discharged
completely.)

→ It is stopped once and switchback operation

is performed. (To the back copy)

→ R-SPF gate solenoid OFF
→ The document is discharged to the document

exit tray.

Paper transport: Switchback operation is performed.

→ The paper is sent through the upper side of

the gate section and the duplex transport sec­tion, and the PS roller, and the images on the
back are transferred.

→ It is sent through the fusing section and dis-

charged to the paper exit tray.

C. Back copy

Document transport: By switchback operation, the document is sent

through the PS roller to the exposure section,
where the back of the document is exposed.
→ It is sent to the document exit section by the

transport roller and the paper exit roller.

→ R-SPF gate solenoid ON. The document is

sent to the intermediate tray, (but not dis­charged completely.)

→ It is stopped once and switchback operation

is performed.

→ It is sent through the PS roller and the ex-

posure section (without exposure operation)
to the document exit section.

[8] Adjustment

1. Optical section

A. Image distortion adjustment

There are following two types of image distortion.

●

Horizontal image distortion

●

Vertical image distortion
In this machine, the image distortion is adjusted by changing the paral­lelism of mirrors (copy lamp unit, No. 2/3 mirror unit).

(1) Horizontal image distortion adjustment
a. Summary

Parallelism of mirrors can be made by installing the copy lamp unit
and No. 2/3 mirror unit to the reference position. However, it must
be checked by making a copy, and must be adjusted if necessary.

b. Cases when the adjustment is required

1) When the copy lamp unit and No.2/3 mirror unit are disas­sembled or their part is replaced.

2) When the copy lamp unit and No.2/3 mirror unit drive section is
disassembled or its part is replaced.

3) When the copy image is distorted as shown below:

4) Manually turn the copy lamp unit/No.2/3 mirror unit drive gear to
bring No.2/3 mirror unit into contact with No.2/3 mirror unit
positioning plate. When No.2/3 mirror unit makes contact with
No.2/3 mirror unit positioning plate in the rear frame side simul­taneously, the mechanical parallelism of No.2/3 mirror unit is
proper.
If one side of No.2/3 mirror unit makes contact with No.2/3 mir­ror unit positioning plate and the other side does not, the paral­lelism is improper.
If the parallelism is improper, perform the procedure of step 5).

8 – 1

5) Loosen the copy lamp unit/No.2/3 mirror unit drive pulley
setscrew in the side where No.2/3 mirror unit does not make
contact with No.2/3 mirror unit positioning plate.

AR-F151

7) Manually turn the copy lamp unit/No.2/3 mirror unit drive gear to
bring No.2/3 mirror unit into contact with the positioning plate,
and perform the procedure of step 4).
Repeat procedures of steps 4) to 7) until the parallelism of
No.2/3 mirror unit is properly set.

8) With No.2/3 mirror unit positioning plate in contact with No.2/3
mirror unit, bring the copy lamp unit into contact with the right
frame and fix the copy lamp unit to the drive wire.
Procedures 1) to 8) are for adjustment of mechanical horizontal
parallelism. The copy lamp unit and No.2/3 mirror are fixed to
the specified positions and the mechanical horizontal parallelism
of No.2/3 mirror is adjusted.
Then the optical horizontal parallelism must be adjusted in the
following procedures.

6) Without moving the copy lamp unit/No.2/3 mirror unit drive pul­ley shaft, manually turn the copy lamp unit/No.2/3 mirror unit
drive pulley in the same direction of the loosened setscrew.
When it makes contact with No.2/3 mirror unit positioning plate,
tighten and fix the setscrew.

9) Set the image distortion check chart on the document table, and

e. Adjustment procedure

1) Set the test chart for image distortion adjustment on the docu-

ment glass, and make a normal copy on a paper of A4 or 8 1/2″
× 11″.

2) Check image distortion in the right and the left sides.
If the both vertical lines are in parallel with each other, the right­left distortion balance is proper. (However, there may be some
distortion.)

2) If all the four angles are right angles, there in no distortion and

the following procedures are not required.

Greater distortion

Smaller distortion

13) Tighten the set screw of the copy lamp unit/No.2/3 mirror unit
drive pulley.

14) Check the image distortion in the same manner as step 10).
Repeat procedures 11) to 14) until horizontal image distortion
is eliminated.

AR-F151

3) If the right-left distortion balance is improper, loosen the fixing
screw of No.2/3 mirror unit rail to change and adjust the right-left
balance of No.2/3 mirror unit rail.

(Note)

If the distortion in the lead edge side (when viewed in the paper
transport direction) is greater, change the height of the left rail of
No.2/3 mirror unit.
If the distortion in the rear edge side (when viewed in the paper
transport direction) is greater, change the height of the right rail
of No.2/3 mirror unit.

(1) Outline

The main scanning (front/rear) direction magnification ratio adjust­ment is made automatically or manually.

Automatic adjustment: The width of the reference line marked on
the shading correction plate is scanned to perform the main scan­ning (front/rear) direction magnification ratio adjustment automat­ically.

Manual adjustment: The adjustment is made by manual key opera­tions. (In either of the automatic and manual adjustments, the zoom
data register set value is changed for adjustment.)

The magnification ratio in the sub scanning direction is adjusted by
changing the mirror base (scanner) scanning speed.

(2) Main scanning direction magnification ratio adjustment

a. Note

Before performing this adjustment, the following adjustments must
have been completed. If not, this adjustment cannot be performed
properly.

●

procedures.

7) Execute SIM 48-1 to select the main scanning direction copy

magnification ratio adjustment mode.
To select the adjustment mode, use the copy mode select key.

In the case of the automatic adjustment, when the PRINT switch is
pressed, the mirror base unit moves to the white plate for shading
to scan the width of the reference line, calculating the correction
value and displaying and storing this value.
After execution of the automatic adjustment, go out from the simula­tion mode and make a copy to check the magnification ratio.
If the magnification ratio is not in the specified range (100 ±1.0%),
manually adjust as follows.

(1) Lead edge adjustment

1) Set a scale to the center of the paper lead edge guide as shown

below, and cover it with B4 or 8 1/2″ × 14″ paper.

2) Execute SIM 50 – 01

3) Set the print start position (AE lamp ON) (A), the lead edge void
amount (TEXT lamp ON) (B), and the scan start position (PHOTO
lamp ON) (C) to 0, and make a copy of a scale at 100%.

4) Measure the image loss amount (R mm) of the scale image.

Set C = 10 × R (mm). (Example: Set the value of C to 30.)
When the value of C is increased by 10, the image loss is
decreased by 1mm. (Default: 50)

5) Measure the distance (H mm) between the paper lead edge and
the image print start position.

Set A = 10 × H (mm). (Example: Set the value of A to 50.)
When the value of A is increased by 10, the image lead edge is
shifted to the paper lead edge by 1mm. (Default: 50)

6) Set the lead edge void amount to B = 50 (2.5mm).

When the value of B is increased by 10, the void amount is in­creased by about 1mm. For 25 or less, however, the void amount
becomes zero. (Default: 50)

3) Make a copy and measure the void amount of image rear edge.

Void amount (Standard value: 2 – 3mm)

Scale image

4) If the measurement value is out of the specified range, change the
set value and repeat the adjustment procedure.
The default value is 50.

Note: The rear edge void cannot be checked with the first sheet

after entering the simulation mode, the first sheet after turn­ing off/on the power, or the first sheet after inserting the cas­sette. Use the second or later sheet to check the rear edge
void.

(3) Center offset adjustment

1) Set the self-made test chart for the center position adjustment so
that its center line is aligned with the center mark of the document
guide.

Procedures

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 connector CN10-2 (FG).

3. Execute SIM 8-1. (The developing bias is outputted for 30 sec.)

4. Adjust the control volume (VR-121) so that the output voltage is –
400 ±5V.

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 (radiating plate).

3. Execute SIM 8-3. (The main charger output is supplied for 30 sec
in the grid voltage LOW output mode.)

4. Adjust the control volume (VR-141) so that the output voltage is –
400 ±20V.

5. Execute SIM 8-2. (The main charger output is supplied for 30 sec
in the grid voltage HIGH output mode.)

6. Adjust the control volume (VR-142) so that the output voltage is 580
±10V.

4. Duplex adjustment

A. Adjusting the paper reverse position in memory

for duplex copying

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)

8 – 9

AR-F151

2) Set the test chart so that the scale is positioned as shown below,
in the S-D mode and the D-S mode.

Scale (S-D mode) Scale (D-S mode)

3) Execute simulation 50-18 to make a copy and check the front edge
image loss at the area where the scale is printed.
Adjust the setting so that the front edge image loss is less than 4.0
mm in the R-SPF mode.
An increase of 1 in setting represents an increase of 0.1 mm in
image loss.

2nd printing surface where scale is printed (lower side)

B. Adjusting trailing edge void in duplex copyin

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.
There are two adjustment modes:

1) Image cut rear end void quantity (R-SPF) 50-19(AE)
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.)

2) Paper trailing edge void quantity 50-19 (TEXT)
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.

Paper

The trailing edge void on the first printing surface
is shown above.

Adjust the setting so that the void area is 4 - 5 mm.
An increase in 1 of setting represents 0.1 mm in void area.

(2) Image cut trailing edge void quantity (R-SPF)

1) Set the test chart so that the scale is positioned as shown below.

Scale (D-D mode)

2) Execute simulation 50-19 to turn on the AE lamp and make the
printing mode in the D-D mode.

3) Remove and reinsert the cassette.

NOTE: Make sure to carry out this step before making a copy

during this adjustment.

4) Make a copy and check the void area of the scale on the image.

Adjust the setting so that the void area is 2 - 4 mm.
An increase of 1 in setting represents an increase of 0.1 mm in
void area.
