Toshiba FC-22 User Manual

GENERAL PRECA UTIONS REGARDING THE INSTALLATION AND SERVICE FOR THE COPIER FC-22
The installation and service should be done by a qualified service technician.
1. Transportation/Installation
When transporting/installing the copier, move it by the casters while lifting the stoppers. The copier is quite heavy and weighs approximately 200 kg (441 lb), therefore pay full attention when handling it.
Be sure to use a dedicated outlet with AC 115V or 120V/20A (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.
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, the
damp heater and their periphery.
Be sure not to touch high-voltage sections such as the chargers, the transfer belt and the high­voltage transformer.
Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fan, 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.
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.
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.
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 copier.
5. Disposition of Consumable Parts/Packing Materials
Regarding the recovery and disposal of the copier, supplies, consumable par ts and packing materials, it is recommended to 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 wrist-
band, 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 copier and make
sure that there are no uninsulated charged objects in the vicinity.
Caution : Dispose of used RAM-ICs (including lithium battery)
according to the manufacturer’s instr uctions.
Vorsicht : Entsorgung des gebrauchten RAM-ICs (inklusive
der Lithium-Batterie) nach Angaben des Herstellers.

creased, this may increase the scraping sound which occurs when the paper scrapes on the

mylar sheet as it is transferred by the regis­tration roller. If this scraping sound is irritat­ing, try reducing the aligning amount.
(3) Do the same for ADU, LCF, bypass feeding,
thick paper 2 and thick paper 3.
Note:
When paper thinner than specified is used, paper jams may occur frequently at the registration section. In this case, it is advisable to change (or reduce) the aligning amount. However, if the aligning amount is reduced too much, this could cause the leading edge void to vary adversely. So, when adjusting the aligning amount, try to choose the appropriate amount while checking the leading edge void at the same time.

1.6.2 Feed motor speed adjustment

The paper transport speed of the registration roller vis-a-vis the image pirnt speed can be set to the optimum value.
<Procedure> (1) While pressing the digital keys [0] and [5] simultaneously, turn the power ON. (Adjustment mode) (2) Set five sheets of A4-R (LT-R) paper into the bypass tray. (3) Input [10] and press the [SETTINGS] key to perfor m the continuous printing of five “adjustment
charts” from the bypass tray.
(4) Since the printed sheets of “adjustment charts” are slightly shrunk after being fused, it it required to
wait one or two minutes to cool them for precise adjustment. Then, set those five sheets again into the bypass tray in the same print direction, with the chart face upward.
(5) Without changing the mode [05], enter [406] and press [START].
While the “adjustment chart” sheets are fed and transported, the pitches in the black belt zone are read.
(6) The step (5) is to be repeated five times automatically.
The displayed set v alue does not change until the fourth printing round and at the finel fifth round, a newly set value is displayed.
(7) When a newly set value for aligning is displayed at the fifth round, press the [INTERRUPT] key to
update the set value. If ERROR is displayed at the second paper feeding, press the [CLEAR] key and return to the step (2).

1.14 High-Voltage Transformer Settings

1.14.1 Overview

This machine uses four main high-voltage transformers for charging/development/discharging and one transfer transformer for transfer/suction. The main high-voltage transformers (PS-HVT-M-310) are used each for one of the colors Y, M, C and K, giving a total of four units. The transfer transformer (PS-HVT-TB-310) supplies high-voltage for the transfer rollers Y, M, C and K and the suction charger to be used in black mode.
The main high-voltage transformers have the following high-voltage outputs.
CH1: main charger wire CH2: main charger grid bias CH3: developer bias CH4: cleaning blade bias
The transfer transformer has the following high-voltage outputs.
CH1: transfer roller bias (Y) CH2: transfer roller bias (M) CH3: transfer roller bias (C) CH4: transfer roller bias (K) CH5: suction charger
* CH5 is used in black mode only.
The main high-voltage transformer and transfer transformer for service parts are supplied with the data sheets to be used for the following setup. Be careful not to lose them. Output adjustment is performed when the devices are shipped, so under any circumstances, do not move the resistors fixed to the board.

Note :
1. When winding the wires on the pulleys, take the following precautions:
· Do not wind the wire on the pulley with
the wire twisted.
· Wind the wire strongly so that all the turns
of the wire are in firm contact with the surface of the pulley.
· Each time you wind a turn on the pulley ,
push it to the preceding turn so that all the turns are closely wound.
2. When fitting wire holder jigs, take care so that the turns wound on the pulleys do not move or unwind.
