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.

AR-F152

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 an 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

230V model and 240V model.

9. 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 “Connecting 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.

10. 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.

● 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”.

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.

(power supply PWB )

2. The surface temperature of the upper heat roller is set to 165˚C ∼ 190˚C. The surface temperature during the power save mode is set to 100˚C.

3. The self-check function comes active when one of the following malfunctions occurs, and an "H" is displayed on the multicopy window.

a. When the heat roller surface temperature rises above 240˚C. b. When the heat roller surface temperature drops below 100˚C

during the copy cycle. c. Open thermistor d. Open thermal fuse e. When the heat roller temperature does not reach 190˚C within

27 second after supplying the power.

(4) Fusing resistor Fusing resistor

This model is provided with a fusing resistor in the fusing section to improve transfer efficiency. General descriptions are made in the following.

General descriptions

Since the upper heat roller is conductive when copy paper is highly moist and the distance between the transfer unit and the fusing unit is short, the transfer current leaks through 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 allow you to install or remove the tray from the front cabinet. The general descriptions on the tray paper feed and the manual paper feed are given below.

(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.

PFS

RRS

OFF

5) At this time, the paper is fed past 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.

PFS

RRS

OFF

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

PFS

RRS

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 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.

PFS

RRS

OFF

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, stopping rotation of the pick-up roller.

8) The paper separated from the drum is passed through the fusing paper guide, the heat roller (fusing section), POD (paper out detector) to the copy tray.

6 – 5

(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.

MPFS

2) When the PRINT button is pressed, the manual paper feed solenoid (MPFS) turns on to disengage the manual paper feed latch 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.

AR-F152

MPFS

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 make synchronization with the lead edge of the image on the OPC drum. The operations hereinafter are the same as the paper feed operations from the tray. (Refer to A-5 ∼ 8.)

5) The solenoid turns off to close the gate and return to the initial state.

MPFS

3) When pawl C of the manual paper feed clutch sleeve is hung on the manual feed latch, the manual feed stopper falls and the manual take-up roller rises. At that time, the manual paper feed roller is rotating.

MPFS

(3) Conditions of occurrence of paper misfeed

a. When the power is turned on:

PPD or POD is ON when the power is turned on.

b. Copy operation

a. PPD1 jam 1) PPD1 does not turn off within 4 sec

after turning on the resist roller.

b. PPD2 jam 1) PPD2 is off immediately after turning on

the resist roller.

2) PPD2 does not turn off within 1.2 sec after turning off the resist roller.

6 – 6

AR-F152

c. POD jam 1) POD does not turn on within 2.9 sec

after turning on the resist roller.

2) POD does not turn off within 1.5 sec ∼

2.7 sec after turning off PPD2.

6. Process unit new drum detection mechanism

1) When the power is turned on, the detection gear 38T is rotated in the arrow direction by the detection gear 20T to push the microswitch (process detection switch) installed to the machine sensor cover, making a judgement as a new drum.

Gear 20T

[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 Freat and 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-F152

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.

e. Adjustment procedure

1) Set the test chart for image distortion adjustment on the document 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.

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.

3. High voltage adjustment

A. Main charger (Grid bias)

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.

B. DV bias adjustment

Note:

●

A digital multi meter with internal resistance of 1GΩ must be used for correct adjustment.

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)

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.

3) Using the user simulation [18], set the paper size of the first cassette.

Letter paper: 4 A4 paper: 3

4) Execute simulation 50-19 to turn on the TEXT 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

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

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. 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.
