GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR e-STUDIO160/200/250 SERIES

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

1. Transportation

• When transporting/installing the copier, employ two persons and be sure to use the positions as

indicated below.

The copier is fairly heavy and weighs approximately 50 kg (110 lb), therefore pay full attention

when handling it.

4 portions

2. Installation

• Be sure to use a dedicated outlet with AC 115 or 120V/15A (220V, 230V, 240V/10A) or more for its

power source.

• The copier 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 copier emits a slight amount of ozone.

• To insure adequate working space for the copying operation, keep a minimum clearance of 80

cm (32") on the left, 80 cm (32") on the right and 10 cm (4") in the rear.

• After having installed the copier, be sure to push the carrying handles into the copier.

3. 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, the

damp heater and their periphery.

• Be sure not to touch high-voltage sections such as the chargers and the high-voltage transformer.

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

• 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.

December 2002 TOSHIBA TEC e-STUDIO160/200/250 GENERAL PRECAUTIONS

• Avoid exposure to laser radiation during servicing.

– Avoid direct exposure to 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.

4. 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.

5. 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 copier.

6. Disposition of Consumable Parts/Packing Materials

• Regarding the recovery and disposal of the copier, supplies, consumable parts and packingm a -

terials, it is recommended to follow the relevant local regulations or rules.

7. 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, toothed washers in the wrong places.

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

9. 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 wrist band, pull out the power cord plug of the copier and make

sure that there is no uninsulated charged objects in the vicinity.

Caution: Dispose of used batteries and RAM-ICs including lithium batteries according to the

manufacturer's instructions.

Attention: Se débarrasser de batteries et RAM-ICs usés y compris les batteries en lithium

selon les instructions du fabricant.

Vorsicht: Entsorgung des gebrauchten Batterien und RAM-ICs (inklusive der Lithium-Batterie)

nach Angaben des Herstellers.

• Explanation of status display

When the sensor test is carried out, the status

of each sensor is indicated on the display with

0 or 1.

Each signal is divided into 8-bit blocks.

The character on the left edge of the display

indicates as follows:

A: Signal input to ASIC

I: Signal input to the IO port

S: Signal from the scanner or R/ADF

P: Signal from the option connected to the

PFC

The display is switched using the or key.

Example 1:

Confirm whether the front cover is open or close.

The front cover is equipped with the 24-V ON/OFF

switch (Interlock switch) and the front cover switch.

The status of both switches is 1 when the cover is

open, and 0 when it is close.

When the status of the one is 0 and that of the other

is 1 as shown in the example, there is something

wrong with either of these switches.

Example 2:

Confirm whether or not the optional memory PWA

is installed, with the status of bits 6 and 7 of IO1 on

the display.

Memory expansion slot on the back of the copier

As shown in the table below, bits 6 and 7 detect the

upper slot and lower slot, respectively.

The installation of the memory PWA can be con-

firmed with these bits.

cedure can be used.

Notes: 1. When frequent paper jams occur near the aligning roller caused by using special thin paper

other than that specified, the aligning value can be changed (reduced) as a measure. However,

when the aligning value is reduced excessively, this may possibly cause the registration to be

shifted. Therefore, make sure that no registration shifting occurs while adjusting the value.

2. Long size adjustment is used as the base when there are both long and short adjustments.

3. Adjusts the code only for option attached.

* As a tentative countermeasure, the service life of the feed roller can be extended by increasing the

aligning amount.

1.7.2 Precautions

(1) Developer bias

Caution during Adjustment

If fogging appears over the entire surface even though the grid voltage are appropriate, adjust the

developer bias on the control panel. The following defects may occur if the developer bias is

lowered too much:

• Image contrast becomes low.

• Image is patchy or blurred.

• Developer carrier adheres to the photosensitive body, making it easier for scratches to occur or

the surface of photosensitive body by the cleaner blade.

December 2002 TOSHIBA TEC 1 - 71 e-STUDIO160/200/250 ADJUSTMENT

(2) Transfer

Items to Check before Adjustment

Pockmarks or defective transfer also occur in defects besides transfer output adjustment defects.

If this happens, check the following items. If an error is not found after carrying out the following

checks, adjust the output.

• Is the charger wire out of position or dirty? Are the transfer guide and roller deformed?

• Are the developer magnetic brushes contacting with the drum?

Is the process unit rotating during copying? Is the toner low?

• Is the copy paper bending as it is being fed in? Is the copy paper abnormally moist?

• Is the aligning roller rotating normally?

• Is the separation output deviating from the set value?

• Is the developer bias an appropriate value?

• Is the transfer/separation charger case earthed? Is the photosensitive drum (shaft) earthed? Is

the transfer/separation transformer earthed?

Caution during Adjustment

When pockmarks occur:

• If pockmarks are occurring in halftone areas, lower the transfer output value. However, note

that if the transfer output value is lowered too far, the transfer performance also will be re-

duced.

When defective transfer occurs:

Increase the transfer output value under the following conditions. However, note that if the

transfer output value is raised too far, pockmarks will occur.

• If defective transfer occurs even though the charger wire is not dirty.

• If thick paper is frequently used.

The adjustment code varies according to where pockmarks occur. Select the required adjust-

ment code while referring to the following diagram.

e-STUDIO160/200/250 ADJUSTMENT 1 - 72 December 2002 TOSHIBA TEC

(3) Separation

Items to Check before Adjustment

Defective separation from the drum also occurs in other than separation output adjustment de-

fects. If this happens, check the following items. If an error is not found after carrying out the

following checks, adjust the output.

• Is the charger wire out of position or dirty?

• Are the developer magnetic brushes contacting with the drum?

Is the process unit rotating during copying? Is the toner low?

• Is the copy paper bending as it is being fed in? Is the copy paper abnormally moist?

• Is the alignment roller rotating normally?

• Is the main charger outputting?

• Is the transfer output deviating from the set value?

• Is the transfer/separation charger case earthed? Is the transfer/separation transformer earthed?

Caution during Adjustment

When defective separation occurs:

Increase the separation output value under the following conditions. However, note that if the

separation output value is raised too far, pockmarks will occur, and separation performance

will be reduced. (Adjustment code = 233)

• If defective separation occurs even though the charger wire is not dirty.

• If thin paper is frequently used.

When defective transfer occurs:

• Lower the separation output value when defective transfer occurs. However, note that if the

separation output value is lowered too far, the separation performance also will be reduced.

The adjustment code varies according to where the defective transfer occurs. Select the

required adjustment code while referring to the following diagram.

1.11 Measurement of Transfer Guide Bias

The transfer charger bias is applied to the pinch roller and the paper guide plate to prevent the transfer

charger charge from escaping through the recording paper during transfer. To analyze the cause of a

transfer failure which has occurred, you can output the transfer guide bias in the output test at any time

and then measure the voltage.

Important:

Measure the transfer guide bias with the toner cartridge and the process unit taken out from the copier

and the front cover open. Also, keep the front cover switch and interlock switch (front cover) ON by using

the switch jigs (big/small).
