6560 PRECAUTIONS 1 DEC.1996 TOSHIBA CORP.

GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND

THE SERVICE OF THE 6560

1. Transportation/Installation

When transporting the copier, move it by the casters while lifting the stoppers.

The copier is quite heavy and weighs approximately 230 kg (507 lb); therefore, pay full attention

when handling it.

2. Installation

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

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 copying operations, keep a minimum clearance of 80 cm

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

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-voltages sections such as the chargers and the high-voltage transformer.

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

When servicing the machines with the main switch turned on, be sure not to touch live sections

such as the lamp terminal etc.

Use suitable measuring instruments and tools.

6560 PRECAUTIONSDEC.1996 TOSHIBA CORP. 2

4. Main Service Parts for Safety

The thermofuse,thermistor,fuse,breaker and door switches,thermostat etc. are particularly important

for safety.Be sure to handle/install them properly.

5. Notice Labels

Be sure to check the rating plate and the notice labels such as "Unplug the power cord during

service" ,"Hot area" ,etc. to see if there is any dirt on their surface or if they are properly stuck to

the copier during servicing.

6. Disposition of Consumable Parts/Packing Materials

Regarding the recovery and disposal of the copier, supplies, consumable parts and packing

materials, 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 be damaged due to static electricity.

2.10 Check/Adjustment of High-voltage Transformer

When replacing the high-voltage transformer,check and adjust the main charger,transfer

charger,separation charger,and developer bias voltage.

2.10.1 Check/Adjustment of Transfer Charger/Separation Charger/Pre-transfer Discharge Charger

(1) Separation

Items to Check before Adjustment

Check that the charger wire is positioned correctly and is clean. Also check that the separation

charger guide is correctly positioned.

Check that the developer unit is installed, and that the magnetic brush is in contact with the drum.

Check that the developer unit turns when a copy is being made. Check also that the toner density

is set sufficiently high.

Check that the copy paper is flat and dry.

Check that the aligning rollers rotate correctly.

Check the output of the grid (for the main charger).

Check that the transfer output is at the set value.

Check that the developer bias is appropriate.

Check that the transfer/separation charger case is earthed. Check also that the high-voltage

transformer is earthed.

CAUTIONS

(1) When pockmarks occurs:

When irregularities (pockmarks) are generated on the halftone areas, reduce the separation output.

Note:

Do not reduce the output excessively. Otherwise, the separation ability will decrease.(2) Defective separation:

When defective paper separation occurs despite the charger wires being clean, or when the user is

likely to use a large quantity of thin paper, raise the output.

Note:

Do not increase the output excessively, otherwise pockmarks will be generated and the separation

ability will decrease.

As with the toner and the developer material, store the selenium drum in a dark place at an

ambient temperature of 10 to 35C(50-95F) where dew will not occur. In particular,avoid high

temperatures,chemical reagents, and gases emitted therefrom.

(3) Main blade

Store the main blade in a flat place at an ambient temperature of 10 to 35C(50-95F). In particular,

avoid high temperatures, chemical reagents, and gases emitted therefrom.

(4) Upper and lower heat rollers

Store the upper and lower rollers away from high humidity, chemical reagents, and gases emitted

therefrom.

(5) Cleaning felt roller

Store the roller away from high temperatures,chemical reagents and gases emitted therefrom.

Also store felt rollers so that they lie horizontal.

(6) Copy paper

Store the copy paper away from high humidity. In particular, be sure to store paper which has been

removed from its original package, In a storage pouch. During the rainy season or when heating in

winter, the temperature and humidity of the room will often fluctuate.

5.2 Inspection and Cleaning of the OPC Drum

(1) Precautions when handling the drum

Use of gloves

If fingerprints, oil, and so on, get onto the selenium surface, the image will be adversely affected.

Accordingly, clean the OPC surface with a soft pad.

Installing and removing

Because the OPC surface is extremely weak, handle with great care in order not to damage it

when installling and removing the drum.Before installing the cleaner unit in the copier, be sure to apply patting powder (lubricant)

around the periphery of the drum.

(Note)1. The procedure is designed to reduce the friction between the drum and blade. If it is not

done, there is a risk of scratching the drum and blade.

(Note)2. If pieces of thread or paper fibers adhere to the drum, cleaning will become more difficult and

also the drum and blade may become scratched. Accordingly, remove any such thread or

fibers immediately.

5-2DEC.1996 TOSHIBA CORP. 6560 PRECAUTIONS

Machine installation place and drum storage place

Install the machine in a place which is not subjected to high temperatures or humidity, and isaway

from chemical reagents and their gases.

Do not leave the drum lying in a bright place for any length of time. Do not expose the drum to light,

especially to long wavelength light(red light) or sunlight.

During servicing, cover the drum with a drum cover so that it is not exposed to light.

(This would cause the drum to become fatigued and prevent sufficient image concentration from

being obtained immediately after the drum is installed in the machine. After a lapse of time, however,

this fatigue will disappear.)

Cleaning

During normal servicing, lightly rub the drum with the specified cleaning cotton (soft pad).

Ensure that the cotton is sufficiently thick and take care not to touch the drum face with your

fingertips or fingernails. Also, before cleaning, remove rings, watches, and so on, to prevent the

drum surface from being damaged. Do not under any circumstances use other organic reagents or

silicone oil to crean the drum as these substances have a detrimental effect on the drum. Do not

use selenium refresher on the drum of the 6560.

If the drum is cleaned with a dry cloth, halftoned images on the cleaned areas may become whitish

but the drum will return to normal after approximately 100 copies have been made.

Repairing scratches on the OPC drum

If the drum is scratched to such an extend that the aluminum surface is exposed, an image will not

appear on that portion, and also the blade may become damaged, hence the drum must be replaced.

The traditional method of repairing scratches on the drum is to use cellophane tape; however it

must not be used on this drum owing to the risk of damaging the blade or preventing satisfactory

cleaning from taking place.

Replacement of the OPC drum

After removing the used OPC drum from the machine, be sure to place it in the drum box, record the

necessary items on the warranty card and insert the card in the box, then paste a 'USED' label on the

outer box and return the box to its specified piace. Never leave a OPC drum lying around.
