GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR e-STUDIO203S/203SD

The installation and service should be done by a qualified service technician.

1. Transportation/Installation

- When transporting/installing the machine, be sure to use the positions as indicated below. The machine is quite heavy and weighs approximately 16.8 kg (37 lb.), therefore pay full attention when handling it.

- Be sure to use a dedicated outlet with AC120V/8A, 220-240V/5A, 230-240V/5A for its power source.

- The machine must be grounded for safety. Never ground it to a gas pipe or a water pipe.

- Select a suitable place for installation. Avoid excessive heat, high humidity, dust, vibration and direct sunlight.

- Also provide proper ventilation as the machine emits a slight amount of ozone.

- The socket-outlet shall be installed near the machine and shall be easily accessible.

2. Service of Machines

- Basically, be sure to turn the main switch off and unplug the power cord during service.

- Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit and their periphery.

- Be sure not to touch high-voltage sections such as the chargers and the high-voltage transformer. Especially, the board of these components should not be touched since the electric charge may remain in the capacitors, etc. on them even after the power is turned OFF.

- Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fan, etc.

- Be careful when removing the covers since there might be the parts with very sharp edges underneath.

- When servicing the machines with the main switch turned on, be sure not to touch live sections and rotating/operating sections. Avoid exposure to laser radiation.

- Use suitable measuring instruments and tools.

- Avoid exposure to laser radiation during servicing.

- Avoid direct exposure to the beam.

- Do not insert tools, parts, etc. that are reflective into the path of the laser beam.

- Remove all watches, rings, bracelets, etc. that are reflective.

- Unplug the power cable and clean the area around the prongs of the plug once a year or more. A fire may occur when dust lies on this area.

3. Main Service Parts for Safety

- The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important for safety. Be sure to handle/install them properly. If these parts are shorted circuit and/or made their functions out, they may burn down, for instance, and may result in fatal accidents. Do not allow a short circuit to occur. Do not use the parts not recommended by Toshiba TEC Corporation.

4. Cautionary Labels

- During servicing, be sure to check the rating plate and the cautionary labels such as “Unplug the power cord during service”, “Hot area”, “Laser warning label” etc. to see if there is any dirt on their surface and whether they are properly stuck to the machine.

5. Disposition of Consumable Parts, Packing Materials

- Regarding the recovery and disposal of the machine, supplies, consumable parts, packing materials, follow the relevant local regulations or rules.

6. When parts are disassembled, reassembly is basically the reverse of disassembly unless

otherwise noted in this manual or other related documents. Be careful not to reassemble small parts such as screws, washers, pins, E-rings, star washers in the wrong places.

7. Basically, the machine should not be operated with any parts removed or disassembled.

8. Precautions Against Static Electricity

- The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband, because the ICs on it may become damaged due to static electricity.

Caution: Before using the wristband, pull out the power cord plug of the machine and

make sure that there are no uninsulated charged objects in the vicinity.

CAUTION

This product is a class 1 laser product that complies with 21CFR 1040 of the CDRH standard and IEC60825-1. 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. Note for servicing and handling

When the main unit power is repeatedly turned OFF/ON rapidly (for about 1sec), the IC (OA982) on the MCU PWB may malfunction to cause an error (E1-00 Communication error), which does not boot the machine. In case of this error, the blank display is kept for several tens seconds and then "E100" is displayed on the panel display.

Turn off the power and keep it for more than 10sec. Then turn on the power. When the machine is booted.: There is no problem in the MCU PWB. When the machine is not booted.: The MCU PWB trouble

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.

(provided in three locations)

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 applied negative charge.

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.

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 Scorotr o n 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.

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.

START STOP

Print potential

Start

1) Because the grid potential is at a low level, the drum potential is at about -400V. (Carri er 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 photoconductor 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.

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 pap er 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.

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.

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.

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.

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.

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 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 A-5 - 8.)

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

4) 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)

5) 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).

6) 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.)

* The RADF adjustment is made by adjusting the RADF image

scan start position after OC adjustment.

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 star ting at the printing star t 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.

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 (RADF) 50-19 (SCAN mode lamp) The size (length) of a document read from the RADF is detected, the image at the trailing edge of the first printing surface is cut to make a v oid 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 (PRINT mode lamp) 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 (RADF) is adjusted.

The adjustment modes can be selected by pressing [ (Adjustment range; 1 – 99)

Enter the adjustment value and press [START] key to save the set value and make a copy. (The paper information is cleared for every copy.)

←/→] key.

3) Execute test command 50-19 to turn on the PRINT mode 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.

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.

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. l Void position to be checked

5. RADF scan position automatic

adjustment

Place a A4 paper (white chart) so that it covers the RADF scan glass and the OC glass together, and close the RADF.

When test command 53-08 is executed, the current adjustment value is displayed as the initial display.

* Default is 1. Adjustment range is 1 – 99. Adjustment unit 1 =

about 0.127mm

* If the values are kept as the default values, RADF scan is not per-

formed properly. The front area of the proper scan position may be scanned.

In case of AUTO, press [START] key, and the mirror unit scans from the home position to the RADF scan position with the adjustment value displayed. The RADF glass cover edge position is calculated from the difference between the RADF glass cover edge and the OC side document glass CCD output level. If the adjustment is normal, the adjusted value is displayed. If abnormal, the error LED lights up with the current set value displayed.

During the error LED is lighted, when [ST AR T] k e y is pressed again, execution is performed again.

6. RADF mode sub scanning direction magnification ratio adjustment

Note : Before performing this adjustment, be sure to check that the

OC mode adjustment in copying has been completed.

1) Put a scale on the original table as shown below, and make a

normal copy (100%) on the front and the back surfaces to make a test chart.

Note : Since the printed copy is used as a test chart, put the scale

in paralled with the edge lines.

2) Set the test chart on the RADF and make a duplex copy (D-D

or D-S) in the normal ratio (100%).

3) Compare the scale image and the actual image.

If necessary, perform the following adjustment procedures.

4) Execute TC 48-05.

5) The current front surface sub scanning direction magnification

ratio correction value is displayed in two digits on the display section. To select SIDE1 and SIDE2, use [←/→] keys.

6) Enter the set value and press the start key.

When adjusting the RADF, use [2-SIDED COPY] key to select single/duplex after entering the one page print mode, performing 2-page single copy.
