CAUTION

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 servic ing.

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 rem oving 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 s afety interlock by inserting wedges or other items into the switch slot.

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.

The foregoing is applicable only to the 220V model, 230V model and 240V model.

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.

Exposure (semiconductor laser)

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.

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.

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.

:Carrier (Magnetized particle) :Toner (Charge negative by friction) (N) (S) Permanent magnet

(provided in three locations)

MG roller

About DC 5.2kV

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-4: Transfer

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.

Toner is attracted over the shadowed area because of the developing bias.

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.

Time

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.

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.

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 Start key after lighting the ready lamp. The paper feed latch is in contact with the projection of the clutch sleeve.

2) When the Start key 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 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.

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.

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.

AL-2041 OPERATIONAL DESCRIPTIONS 7 - 5

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.

(2) Manual multi paper feed operation

MPFS

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

3) When pawl C of the manual paper feed clutch sleeve is engaged with 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.

2) When the Start key 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.

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 7-5 - 8.)

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

The copy magnification ratio must be adjusted in the main scanning direction and in the sub scanning direction. To adjust, use SIM 48-1.

(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 [Copy quantity] keys 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 carriage (scanner) scanning speed.

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)

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.

• Test chart for the center position adjustment.

Draw a line at the center of A4 or 8 1/2" x 11" paper in the paper transport direction.

2) Execute SIM 50-10 to select the print center offset (cassette paper feed) adjustment mode. The set adjustment value is displayed on the copy quantity display.

3) Make a copy and check that the copied center line is properly positioned. The standard value is 0 ± 2mm from the paper center.

(2) Image rear edge void amount adjustment

1) Set a scale to the rear edge section of A4 or 11" x 8 1/2" paper size as shown in the figure below, and cover it with B4 or 8 1/2" x 14" paper.

2) Execute SIM 50-01 to select the image rear edge void amount adjustment mode. The set adjustment value is displayed on the copy quantity display.

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

Scale image

4) If the measured value is out of the specified range, change the set value and repeat the adjustment procedure. When the set value is increased by 1, the copy image is shifted by 0.1mm toward the rear frame.

• For the manual paper feed, change the manual paper feed

adjustment mode and perform the similar procedures.

• Since the document center offset is automatically adjusted by

the CCD which scan the reference lines (F/R) on the back of document guide, there is no need to adjust manually.

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.

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 SIM 8-2. (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.

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

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 SIM 8-1 to output the developing bias for 30sec, and check that the output is –400 ± 8V.

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)

AL-2041 ADJUSTMENTS 9 - 5

4) Execute SIM 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.

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) Paper trailing edge void quantity 50-19 (TEXT) This adjustment is made when the cassette paper size is rec-

[Adjustment procedure]

1) 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%.

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.)

[Function]

When this simulation is executed, the current set correction value is displayed. Enter the correction value and press [START] key to save the entered correction value. (Correc-

tion value range; 1 – 99, Default: 50) For S-D mode front surface print, 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 out-

put 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 simulation 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 simulation.

Since it is performed by changing the scan end position, the image position adjustment is made by changing the scan end position and the end data stored in memory.

The adjustment modes can be selected by pressing [Exposure mode selector] key.
