[1] GENERAL
1. General
This model is a digital personal copier produced with key words of "Comfort able copy, Clear copy, Easy copy" providing high copy per­formances and copy productivity.
2. Target user copy volume: Monthly average
Stand-alone copier: 2000~3000 sheets Compound machine: 4000~5000 sheets
3. Main features
A. High-speed laser copying
First-copy time is only 7.2 seconds (normal mode).
Copying speed is 16 copies/min., which adapts to business use,
allowing improvement of working efficiency.
B. High-quality digital image
High-quality copying at 600 dpi is performed.
In addition to the automatic exposure mode, the manual exposure
can be adjusted in five steps.
The photo mode copying function allows clear copying of delicate
halftone original images such as monochrome photos and color photos. Photo mode is adjustable in five steps
C. Substantial copying features
Zoom copying from 50% to 200% in 1% increments can be per-
formed.
Continuous copying of maximum 99 sheets can also be per-
formed.
Useful special features such as the XY zoom, black and white
reverse, and dual page copy are available.
Toner save mode reduces toner consumption by approximately
10%.
User programs allow setting/modification of functions for customer
needs. Also the user programs allow the internal auditor to be controlled.
D. Scan once/ Print many (Only AR-161 for
USA/Canada)
The copier is equipped with a 1-page memory buffer. This memory
allows the copier to scan an original 1 time only and make up to 99 copies. This feature allows for improved workflow, reduced operat­ing noise from the copier and reduced wear and tear on the scan­ning mechanism, which provides for a higher reliability.
E. Optional features
An optional single pass feeder (SPF) allows automatic document
feeding of up to 30 sheets.
An optional electronic sort board allows many useful copier fea-
tures to be used. Multiple sets of copies can be sorted without the aid of a sorter and each set can be offset from the previous set. Also the erase, margin shift, and 4 in 1 and 2 in 1 functions are available. (To use the 2 in 1 and 4 in 1 and sort/group functions, an optional SPF is also needed.) (Offset only for AR-161)
This copier can be used as a laser printer by installing an optional
printer upgrade kit. (Depends on the destination)
This copier can be used as a facsimile machine by installing an
optional facsimile upgrade kit. (Depends on the destination)
F. Environmentally friendly design
Paper output tray is housed in the copier for space saving.
Preheat mode and auto power shut-off mode are provided to
reduce power consumption in standby mode.

A. Scan process
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 an image which is scanned is shown with solid 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 5 sections. Actually, however, one line is divided into thousands of sections. For scanning, the light receiving element called CCD is used.

The image is converted into electrical signals by the CCD circuit
and passed to the MCU.
D. Image process: MCU
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.
E. Electric signal/Photo signal (laser beam)
conversion: LSU
The LSU emits laser beams according to the print data. (Electrical
signals are converted into photo signals.)
The laser beams are radiated through the polygon mirror and
various lenses to the OPC drum.
F. Printing: Process section
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).
Meanwhile the paper is fed to the image transfer section in
synchronization with the image lead edge.
The toner image is transferred on the paper.

B. Outline of print process
The printer section of this machine employs the laser print system where print images are formed by the laser beams on the OPC drum.
A high voltage (corona) is applied from the main charger to the OPC drum to charge the OPC drum.
Laser beams are radiated to the charged OPC drum to form electrical images on the OPC drum. (Exposure)
(At that time, the print image on the OPC drum cannot be seen: latent electrostatic image)
By the potential difference between the unexposed area and the latent electrostatic images, toner ia attracted only to the im­ages.(Developing)
(At that time, the print image formed by toner on the OPC drum can be seen. Visible images)
The toner image on the OPC drum is transferred on the print paper by the transfer corona (voltage).
After that, the print paper with the toner image on it is subject to heat and pressure in the fusing section to fuse the image on the paper.
This machine employs the following organic photoconductor (OPC) drum.
An OPC drum is used for the photoconductor. (Structure of the OP C dru m layers)

C. Actual print process
(1) Charging
A high voltage is applied to the main charger, and negative charges are discharged to the OPC drum. A screen grid is provided between the main charger and the OPC drum, and negative charges are uniformly charged on the OPC drum surface.
Positive charges are attracted by the negative electrode on the OPC drum surface and excited in the aluminum layer in the OPC drum.

(2) Exposure
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.

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.

(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.
(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.

(7) Optical discharge (Semiconductor laser)
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.
Semiconductor laser
a. Charge by the Scorotron charger <1> Function
The Scorotron charger functions to maintain the surface potential of the drum even at all times which. It is used to control the surface potential regardless of the charge characteristics of the photoconduc­tor.
<2> 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.
b. Process controlling <1> 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.
<2> 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 the developer unit.

<3> Start
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.

<4> Stop
The reverse sequence takes place.
c. Retaining developing bias at an abnormal occurrence <1> 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.
<2> 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.
4. Laser unit
The image data sent from the MCU (image process circuit) is sent to the LSU (laser uni t), where it is converted in to 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 BD PWB works for measurement of the laser writing start point.

B. Brief descriptions of operations
This machine allows two ways of paper feed system: cassette paper feed and manual paper feed. The cassette of universal type is employed to hold 250 sheets. The front loading system allows to attach or detach the cassette from the front of the machine. Paper size can be selected by the user.
Paper size detection is set by the software. (User setting is allowed.) By installing the optional 1-step paper feed unit or the multi-step paper feed unit, the capacity of paper can be increased.
(1) Cassette paper feed operation
Select the cassette and press the START button, and the paper feed roller solenoid will be turned on and the paper feed clutch will be released. The drive power of the main motor is transmitted through the paper feed roller clutch to the paper feed roller, rotating the paper feed roller and feeding paper.

AR-161
(2) Manual paper feed tray operation
Select the manual paper feed tray and press the START button, and the manual paper feed roller will be turned on to bring the paper feed roller in contact with paper and lift the shutter simultaneously. The drive power of the main motor is transmitted through the manual paper feed roller clutch to the manual paper feed roller, rotating the manual paper feed roller and feeding paper.
(3) Resist roller
In order to make synchronization between the paper lead edge fed from the paper feed port and the image lead edge, the roller is kept stationary for a certain time after the paper reaches at the roller to warp the paper a little. When the paper is warped to a certain level, the resist roller solenoid is turned on to release the resist roller clutch. The drive power of the main motor is transmitted through the resist roller clutch to the resist roller, rotating the resist roller and feeding paper.
6. Fusing section

B. Heat roller
A pressure roller is used for the heat roller and a silicone rubber roller is used for the lower heat roller for better toner fusing performance and paper separation.
C. Separator pawl
Four separator pawls are used on the upper heat roller. The separator pawls are teflon coated to reduce friction with the roller and prevent a smear on the paper caused by the separator pawl.
D. Thermal control
1) The heater lamp, thermistor, main PWB, DC power supply PWB, and triac within the power supply unit are used to control the temperature in the fuser unit.To prevent against abnormally high temperature in the fuser unit, a thermostat is used for safety pur­poses.

E. Fusing resistor
(1) Fusing resistor
Since the upper heat roller is conductive when copy paper is highly moistured 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. To prevent against this, a resistor of 150MOhm is provided between the frame and the discharge brush to minimize leak current and improve transfer efficiency.

(3) Image ASIC (HG73C039FD)
a. Outline
Fig. 4 shows the block diagram of the ASIC. The ASIC is composed of the following three blocks; the image process section, the print control section, and the I/F section. The image process section processes the image data from the CCD PWB according to the operation mode, such as shading, AE process, resolution conversion. and zooming. The print control section outputs the image-processed data during copying to the LSU (Laser unit) in synchronization with writing timing of the LSU. The I/F section controls communication of interface (IEEE1284) with the host PC and controls DRAM of send/receive data buffer with the host PC. (Only for models with the printer function) The ASIC is controlled by the CPU which writes the operation mode and the set values necessary for each operation mode to the ASIC control register.

(5) Reset circuit
This circuit detects ON/OFF of power to control start/stop of each circuit. The 5V voltage of the main PWB is detected by the reset IC to generate the reset signal. When the power voltage reaches the specified level, the circuit operations are started. Before the power voltage falls below the specified level, the circuit operations are stopped to prevent against malfunctions.
(6) Main motor drive circuit
The main motor is driven by the MMD signal from ASIC. While the main motor is rotating, the MMD signal is driven to HIGH and passed through IC35 to the control circuit in the main motor to rotate the main motor. The /MMRDY signal is kept HIGH until the main motor speed reaches the specified rpm, and passed to the CPU.
(7) Mirror motor circuit
The mirror motor is a stepping motor, and it uses the IC29 and the constant current chopper control IC (SLA7027). For control, the CPU outputs the drive signal to the IC29 to drive the mirror motor with 1-2 phase excitement.

(8) Toner supply motor drive circuit
The IC31 is the motor control IC, which generates the pseudo AC waveform with the pulse signals (TM, TM-) outputted from ASIC, driving the toner supply motor.
3. CCD PWB
The CCD PWB is provided with the CCD (Charge-Coupled Device), the differential amplifier which amplifies image signals, and the AD convertor which converts the amplified image signals into digital signals. The DC power and the pulse supply pins necessary for operating the CCD image sensor are the power source (CD pin), GND (SS pin), shift pulse (SH pin), transfer pulse (φ 1 pin), (φ 2 pin), reset pulse (/RS pin), clamp pulse (/CP pin), and sampling (/SP pin). Photo data are stored in the light receiving element at the center of the CCD by the SH signal. Even number pixel data are sent to one of the two shift registers which are positioned at both ends of the light receiving element, and odd number pixel data are sent to the other shift register. The time interval between inputting two SH signals is called the photo accumulation time. The signals are transfered to the register, then to the shift register sequentially by transfer pulses φ 1 and φ 2 and to the floating capacitor section where electric signals are voltage-converted. Electric charges from the even number pixel shift register and the odd number pixel shift register are flowed to the floating capacitor section alternatively.
The /RS signal is the reset signal of the CCD output signal. The CCD output is expressed as electric charges equivalently accumulated in the capacitor. Therefore, to take the CCD output data one pixel by one pixel, one output data must be cleared after it is outputted. The /RS signal is used for that operation.
The /SP pulse signal is the peak hold signal of the signal voltage. The output signal from the CCD is amplified by about 4.7 times greater in the differential amplifier circuit in the CCD PWB. Differential amplification is made for the signal output (OS) and the compensation output (DOS). The amplified CCD signal output is sent to the clamp circuit. In the clamp circuit, the black level is clamped to 2V at the BCLK signal timing by the analog switch. The clamped voltage is maintained for one line by the coupling capacitor. The clamped analog signal is impedance-converted and inputted to the AD convertor. The analog signal inputted to the AD convertor is converted into 8bit digital data and passed to the PCU PWB. The machine employs the TCD1501C as the image sensor. The TCD1501C is the reduction type high sensitivity CCD linear sensor of one-output system. 5000 pixels of 7um x 7um are arranged in line to allow scanning of A3 document at 400dpi (16 lines/mm).
