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.

2. Outline of print process

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

Step-1: DC charge

A uniform negative charge is applied over the OPC drum surface by the main charging unit. Stable potential is maintained by means of the Scorotron charger. Positive charges are generated in the aluminum layer.

Step-2: Exposure (laser beam, lens)

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)

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.

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.

AR-5012 COPY PROCESS 6 - 3

Step-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

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.

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.

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.

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 the developer unit.

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.

(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.

With the signal from the main PWB, the triac is controlled on and off. (power supply PWB)

2) The surface temperature of the upper heat roller is set to 165 190°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.

(4) Fusing resistor

Fusing resistor

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.

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.

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" x 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 X 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 X 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) Image process ASIC (HG73C119HF)

a. General

The ASIC is composed of the three major blocks: the image process section, the print control section, and the I/F section.

Image process section:

With image data from the CCD PWB in the operation mode determined by the register setup, shading, AE process, input γ correc- tion, area separation, filter process, resolution conversion, zoom process, output γ correction, binary conversion (error diffusion, dither method, simple binary conversion) are performed.

Print control section:

When copying, the image-processed data are outputted to the LSU according to the LSU writing timing. When scanning, the image data are made into 8bit width and outputted to the I/F section (USB).

I/F section:

Controls the DRAM which is the image data buffer, and processes data send/receive between the USB I/F and the IEEE1284 I/F.

The ASIC is controlled by writing the operation mode and the necessary setup values of the operation mode into the ASIC control register before starting each operation. (For ASIC Pin configuration, refer to the table at the end of this document.)

(3) Reset circuit

This circuit detects ON/OFF of power to control start/stop of each circuit. The 3.3V 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.

Thermistor

Heat Roller

The lower the heat roller surface temperature is, the greater the thermistor resistance is, and vise versa.

Therefore, the lower the heat roller surface temperature is, the higher the thermistor terminal voltage is, and vise versa. The thermistor terminal voltage is inputted to the CPU analog port.

The CPU controls ON/OFF of the heater lamp by this input voltage level.

AR-5012 ELECTRICAL SECTION 13 - 8

[High temperature protect circuit in case of CPU hung up]

For IC120 3pin (reference voltage), +3.3V is divided by the resistor.

The thermistor terminal voltage is inputted to IC120 2pin.

When, the voltage at 2pin becomes lower than the voltage at 3pin (when the heat roller temperature is about 220 – 230°C), IC120 1pin becomes HIGH, and the HL signal is lowered to the GND potential through IC124, stopping generation of the heater lamp ON signal. (IC120 1pin is normal LOW.)

[When the heat roller surface temperature is lower than the set level]

1) Since the thermistor terminal voltage is higher than the set level, the HL signal from the CPU becomes HIGH.

2) The HL signal is turned to be the HLOUT signal through IC124 protect circuit, and inputted to the photo triac coupler on the power PWB.

3) When the internal triac turns on, a pulse is applied to the gate of the external triac. Consequently a current flow from the power source through the heater lamp to the triac, lighting the heater lamp.

[When the heat roller surface temperature is higher than the set level]

1) Since the thermistor terminal voltage becomes lower than the set value, the HL signal from the CPU becomes LOW.

2) The HL turns LOW, the photo triac coupler on the power PWB turns OFF, the external triac turns OFF, and the heater lamp turns OFF.

[In case of the thermistor open]

The voltage at IC120 6pin over the voltage at 5pin to drive the output THOPEN at 7pin to LOW. This is passed to the CPU and the trouble code "H2" is displayed.

(6) Toner supply motor drive circuit

The IC129 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.

(5) Driver circuit (Solenoid)

a. Outline

Since the load signal from the CPU or the ASIC cannot drive the load directly, it is passed through the driver IC to drive the load.

b. Operation

The driver circuit forms a Darlington circuit with transistors. Therefore a large drive current is obtained from a small current (ASIC output current). When the driver input voltage (base resistance input) is HIGH (+3.3V), the transistor turns ON to flow a current in the arrow direction, operating the load. When the driver is ON, the driver output terminal voltage is 0V.

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 IC125 to the control circuit in the main motor to rotate the main motor. When the main motor speed reaches the specified rpm, the MMLD signal is turned LOW and passed through IC115 to the CPU.

(8) Mirror motor control circuit, Duplex motor control circuit

Stepping motors are employed for the mirror motor, the SPF motor, and the duplex motor. The driver for IC127 (for mirror motor) is the bipolar drive L6219DS, and the driver for IC128 (for SPF) is the unipolar drive IC MTD1361F. For control, the SPF outputs the drive signal from the CPU to the IC, and the mirror outputs the drive signal to the IC with the ASIC. They drive each motor in 1-2 phase excitement or 2phase excitement.

Each motor switches the motor current value in each magnification ratio.

a. General

The carriage unit is provided with the CCD PWB, the inverter PWB, and the lamps. It scans documents and transfers AD-converted image data to the ASIC.

b. CCD PWB

The CCD on the CCD PWB employs the color image sensor uPD8861 of 5400 pixels x 3 lines, and scans documents in the main scanning direction in the resolution of 600dpi/US letter size.

Image data scanned by the CCD are inputted to the AFE (AD9826), and subject to CDS, amplification, and AD-conversion. Then digital data are outputted to the MCU PWB and to the ASIC, which performs image process of the digital data.

c. Lamp inverter PWB

The transformer is controlled by the lamp control signal from the MCU PWB. The transformer output controls lighting of the cool cathode ray tube.

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.

The filter circuit is composed of L and C. It reduces common noises and normal mode noises generated from the AC line.

The common noise means that generated in each line for GND. Its noise component is delivered through C001, C003, and C007 to GND.

The normal noise means that overlapped in the AC line or the output line. It is attenuated by C002, L001, C006, and L002. Refer to fig (2).

fig (4) Inverter and control circuit

This circuit is one-stone separate excitation DC-DC converter called flyback converter, as shown in fig (4).

When an electromotive voltage of IC is applied through D012, R005, and R006 to IC002, IC002 oscillates to conduct Q001.

As a result, a voltage is applied to the primary winding of the converter transformer (T001) and at the same time a voltage is generated in the driving winding of IC002 to operate IC002. Then IC002 turns ON/OFF Q001 at the frequency of about 70KHz determined by R016.

Under the ON state, the voltage in the secondary winding is reversed to the diode D103 and no current flows through the secondary winding of T001.

Under the OFF state, the current flowing through the primary winding is in the same direction as the primary winding, conducting D103 and transmitting energy to the secondary winding. Refer to fig (4).

fig (3) Rush current prevention, rectifying/smoothing circuit

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 C010 when turning on the power.

To prevent against this, the rush current prevention resistor TH001 is provided between the rectifying diode D002 and the smoothing diode C010, suppressing a rush current.

The rectifying/smoothing circuit rectifies a 50/60Hz AC voltage with the rectifying circuit, and smoothes it with the smoothing capacitor C010.

AR-5012 ELECTRICAL SECTION 13 - 12

The control circuit is subject to negative feedback from the secondary side as shown in fig (4). A photo coupler (PC002) is employed to insulate between the primary side and the secondary side to feed back the control signal to the primary side.

When the output voltage is increased by energy transmission from T001, the voltage detected by R109 and R111 is compared with the reference voltage of IC102. When it exceeds the reference voltage, the current flowing through IC102 (that is, the photo diode current of PC002) is increased and transmitted to the primary side. Then the potential at the feedback pin (2 pin) of IC102 is decreased to control Q001. Therefore, the change in the output voltage on the secondary side is passed through IC102 and PC002 to control Q001, stabilizing the output voltage.

(4) Overcurrent protection circuit (Primary side)

The inverter circuit of the primary side is connected with the current detection resistor R102. When an overcurrent occurs in the secondary side, the current flowing through the primary side inverter Q001 is increased. The current is detected by R012, and passed through R013 to IC701 overcurrent restricting pin (3 pin) to turn OFF Q002, shutting off all power. To resupply the power, turn off and on the power. Refer to fig (4).

(5) Rectifying/smoothing circuit (+5V)

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 D103, and smoothed by C103 and C104.
