GENERAL PRECAUTIONS REGARDING THE INSTALLATION
AND SER VICE FOR THE COPIER FC-210/310
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 187 kg (413 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.
• The socket-outlet shall be installed near the copier 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, the
damp heater and their periphery.
• Be sure not to touch high-voltage sections such as the chargers, high-voltage transformer,
exposure lamp control inverter, inverter for the LCD backlight and power supply unit. Especially,
the board of these components should not be touched since the electirc charge may remain in
the condensers, 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.
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 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 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.
V orsic ht :Entsorgung des gebrauchten Batterien und RAM-ICs (inklusive
der Lithium-Batterie) nach Angaben des Herstellers.

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, thick paper 3 and OHP bypass
feeding.
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 margin to vary
adversely. So, when adjusting the aligning amount, try to choose the appropriate amount while checking the
leading edge margin at the same time.
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.
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)Enter [10] and press the [PRINTER/NETWORK] 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 to 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 adjustment mode , enter [406] and press the [START] key.
While the “adjustment chart” sheets are fed and transported, the pitches in the black belt zone are
read.

The following two types of preventive maintenance should be performed:
Note: Values of the sheets correspond to the FC-210/FC-310.
(1)General maintenance (General PM)
General maintenance should be performed based on the value of the general 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 (every 40/60K sheets) of the black developer
material.
(2)Color maintenance (Color PM)
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 (every 40/60K sheets) of the color developer materials.
The cycle (counter value) of color maintenance is determined by the ratio of color printouts to black
printouts, as shown by the following table, "Variation in PM cycles due to color/black printout ratios".
Variation in PM cycles due to color/black printout ratios
a. Discuss current machine conditions with the key operator and note them down.
b.Before starting maintenance, make a few sample copies by TCC-1 chart and keep them for later
reference purposes.
c.Turn OFF the power switch, and be sure to unplug the copier.
(2)Perform preventive maintenance following the checklist shown below. During maintenance, refer to
