GENERAL PRECAUTIONS 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 parts 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 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 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 instructions.
Vorsicht
:
Entsorgung des gebrauchten RAM-ICs (inklusive
der Lithium-Batterie) nach Angaben des Herstellers.

If the paper feed roller has prematurely become defective, it is possible to extend its service life, if
necessary, by increasing the aligning amount, as a temporary measure until a replacement becomes
available.

fer problem is present, try the values in descending order as “31”→“30”→”29"··· until the
transfer void disappears. At the same time,
confirm that any paper jam has not occurred.
Also, when the aligning amount has been increased, this may increase the scraping sound
which occurs when the paper scrapes on the
“Z” fold
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 perform 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 value 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).

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.
No gap should exist.
· 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,
e.g. Front side
push it to the preceding turn so that all
the turns are closely wound.

2. PREVENTIVE MAINTENANCE (PM)
2. 1 Types of Preventive Maintenance
The following two types of preventive maintenance should be performed:
(1)
General maintenance
General maintenance should be performed based on the value of the PM counter (08-857).
This maintenance, which covers the black developer unit as well as the entire machine, should be
conducted in conjunction with the replacement cycle (For FC-22: every 30K Copies, For FC-15:
every 20K Copies) of the black developer material.
(2)
Color maintenance
Color maintenance should be performed based on the value of the color PM counter (08-897).
This maintenance, which is performed with a focus on the color developer units, should be conducted in conjunction with the replacement cycle of the color developer materials.
FC-22: every 30K copies
FC-15: every 20K copies
The replacement cycle (counter value) of color maintenance is determined by the ratio of color copy
to black copy, as shown by the following table, "Variation in PM cycles due to color/black output
ratios".

* Therefore, replacing parts, cleaning and coating oil for the paper feeding unit, scanner unit, transfer/transport unit, fuser unit, all should be checked and maintained in conjunction with the replacement cycle of the black developer material.
e.g. )Replacing fuser rollers
: At the 3rd cycle of replacing black developer material
(30K × 3 = 90K copies)
Replacing the transfer belt : At the 4th cycle of replacing black developer material
(30K × 4 = 120K copies)
* For the details of maintenance items, refer to the checklist described later.
* Yields are based on factory defaults.

3. PRECAUTIONS FOR STORING & HANDLING SUPPLIES
3.1 Precautions for Storing TOSHIBA Supplies
A. Toner and Developer
Toner and developer should be stored in a shaded place where the ambient temperature is between 10
to 35°C (no condensation), and should also be protected against direct sunlight during transportation.
B. Photoconductive Drum
Like toner and developer, Photoconductive drums should be stored in a dark place where the ambient
temperature is between 10 to 35°C (no condensation). Be sure to avoid places where drums may be
subjected to high humidity, chemicals and/or chemical gas.
C. Drum Cleaning Blade
This item should be stored “horizontally” on a flat surface where the ambient temperature is between 10
to 35°C, and should also be protected against high humidity, chemicals and/or chemical gas.
D. Fuser Roller
Avoid places where the fuser rollers may be subjected to high humidity, chemicals and/or chemical gas.
E. Cleaning Roller
Avoid places where the felt roller may be subjected to high humidity, chemicals and/or chemical gas. It
should also be stored “horizontally” on a flat surface.
F. Copy Paper
Avoid storing copy paper in places where it may be subjected to high humidity.
After a package is opened, be sure to place and store it in a storage bag.
3.2 Checking and Cleaning of the Photoconductive Drum
(1) Use of Gloves
If fingerprints or oil stain the OPC drum surface, the characteristics of the photoconductor may degrade,
affecting the quality of the copy image. So, do not touch the drum surface with your bare hands.
(2) Handling Precautions
As the OPC drum surface is very delicate, be sure to handle the drum carefully when installing and
removing it so as not to damage its surface.
When the drum is replaced with a new one, be sure to apply “patting powder” (lubricant) to the entire
surface of the new drum before installing. After installing, the drum counter must be cleared to 0 (zero) by
operating the setting mode 840 – 843 and 867 – 870.
Note:
1. Application of the patting powder is for reducing the friction between the drum and the cleaning blade.
If the application of patting powder is neglected, the drum and the cleaning blade may be damaged.
2. When some fibers adhere to the cleaning blade edge, they may reduce the cleaning efficiency and, in
addition, may damage the blade and the drum. Be sure to remove any fibers found adhering to the
blade.
January 2000 © TOSHIBA TEC
3-1
FC-22 SUPPLIES
(3) Installation of the Copier and Storage of the Drum
Avoid installing the copier where it may be subjected to high temperature, high humidity, chemicals and/
or chemical gas.
Do not leave drums in a brightly lit place for a long time. Otherwise, the drum will be fatigued, producing
some background fog on the copy after being installed in the machine. However, this effect will decrease
as time elapses.
(4) Cleaning the Drum
At periodic maintenance calls, wipe softly the entire surface of the drum using the designated cleaning
cotton (dry soft pad). Use sufficiently thick cleaning cotton so as not to touch the drum surface inadvertently with your fingertips or nails. Also, remove your rings and wristwatch before starting cleaning work to
prevent accidental damage to the drum.
Do not use organic solvents such as alcohol or silicone oil as they will have an adverse effect on the
drum. Never use selenium refresher, either.
(5) Scratches on Photoconductive Drum Surface
If the surface is scratched to such a degree that the aluminum base is exposed, black spots or streaks will
be produced on copy images and can also damage the cleaning blade. So, replace the drum with a new
one.
(6) Collecting Used Photoconductive Drums
Regarding the recovery and disposal of used OPC drums, you should follow your relevant local regulations and rules.
3.3 Checking and Cleaning of the Drum Cleaning Blade and Transfer Belt Cleaning Blade
(1) Handling Precautions
Since the edge of the cleaning blade performs the cleaning operation, pay special attention when handling it:
� Do not allow any hard object to hit or rub against the blade edge. Do not rub the edge with a cloth
or soft pad.
� Do not stain the edge with any oil or fingerprints, etc.
� Do not allow solvents such as paint thinner to touch the blade.
� Do not leave any lint or dirt on the blade edge.
� Do not place the blade near a heat source.
(2) Cleaning Procedure
Clean the blade edge lightly with a cloth moistened with water.
FC-22 SUPPLIES

3.4 Checking and Replacing the Oil Roller and Cleaning Roller of Fuser Section
(1) Handling Precautions
Never allow solvents such as paint thinner to touch to the cleaning roller.
(2) Defective Cleaning and Corrective Treatment
Judgement should be made depending on how much toner has been deposited on the fuser roller surface. When its surface is stained with toner, examine the oil roller and cleaning roller. If toner is heavily
adhered on the oil/cleaning rollers, it means the cleaning performance is declined and the oil/cleaning
rollers should be replaced with new ones.
The oil/cleaning rollers will be gradually degraded due to subjection to the heat from the fuser roller over
a long period of time. Replace them preferably after a fixed amount of copies have been made.
3.5 Checking and Cleaning of the Fuser Rollers
(1) Handling Precautions
Upper and lower fuser rollers
� Do not leave any oil (fingerprints, etc.) on the upper and lower fuser rollers.
� Be careful not to allow any hard object to hit or rub against the fuser rollers, or they may be
damaged, possibly resulting in defective cleaning.
(2) Checking
� Check for stain and damage on the fuser rollers and clean if necessary.
� Clean the separation claws and check for chipped claw tips.
� Check the cleaning effect of the cleaning roller.
� Check the thermistor for proper contact with the fuser roller.
� Check the fused condition of the toner image.
� Check the gap between the inlet guide and lower fuser roller.
� Check the fuser rollers for proper rotation.
(3) Cleaning Procedure for Fuser Rollers
When fuser rollers become dirty, they will cause jamming. If this happens, wipe the roller surface clean
with a suitable cloth. For easier cleaning, clean the rollers while they are still warm.
Note:
Be careful not to rub the fuser roller surface with your fingernails or hard objects because it can be easily
damaged. Do not use silicone oil on the fuser rollers.

3.6 Checking and Replacing the Transfer Belt
(1) Handling Precautions
� Do not touch the belt surface with your bare hands.
� Prevent oil or other foreign matter from staining the belt surface.
� Do not allow alcohol or any other organic solvent to come into contact with the transfer belt.
� Do not apply external pressure that might scratch the transfer belt.
3.7 Checking and Replacing the Transfer Roller
(1) Handling Precautions
� Do not touch the transfer roller surface with your bare hands.
� Be carefull not to leave any scratch or dent on the transfer roller surface.

* Fine adjustment of registration roller paper transport speed
The optimized value is not always obtained for jitter and color deviation because fine error is generated in automatic adjustment.
If uneven color is generated in the secondary-scanning direction of the image and the further adjustment is necessary, perform the following procedure from 1 to 7.
1. Start up with the test print mode [04].
2. Select the A3/LD cassette.
3. Input the code [234] (output the half tone pattern).
4. Select [M] on the control panel and press [START] key. Since the halftone image is to be continuously
printed out, press [STOP] key when the first paper starts being fed, to make only one print.
5. According to the steps 3 and 4, print out the halftone image of cyan (C) and black (K).
6. Criteria for judging paper transport speed by image
Uneven color of 2.5mm pitch in halftone image is generated.
→Paper transport speed is low.
Uneven color is partially generated at 120mm with magenta, 195mm with cyan and 270mm with black
from the trailing edge.
→Paper transport speed is high.
7. Adjust "Fine adjustment of feed motor rotation speed" of code 05-404 by two steps, assuming the
speed status from the grid pattern image and from the above image criteria 6. After adjusting, repeat
the procedure from 1 to 6. When the step value decreases, the paper transport speed becomes
higher.
When the step value increases, the paper transport speed becomes lower. The speed should not be
too low or too high because either case has harmful effect. (The step value should be approx. within
4289±30.)
Note: First perform the adjustments 05-401 to 403, before proceeding to 05-404, "Fine adjustment of feed motor
rotation speed".
If the adjustment 05-406 is performed, the value of 05-404 is changed. Therefore, perform the settings of 05404 again.
