Chapter 1 Service Call Procedure
1.1 Before Starting the Servicing
1-1
1.1 Before Starting the Servicing
1.1.1 Safety
To prevent any accident that may occur during maintenance servicing, any WARNING or CAUTION regarding
the servicing must be strictly observed. Do not perform any hazardous operation.
1Power Supply
To prevent accidents such as electrical shocks, burns, and injury,besuretoswitchOFFthemachine
and disconnect the plug before starting the maintenance servicing. Ifthemachinehastobeswitched
ON, such as when measuring the voltage, take extra care to prevent an electrical shock.
2Drive Area
Never inspect or lubricate the drive area such as the chain belts, sprockets, and gears while the
machine is in operation.
3Heavy Parts
The weight of the machine is 18.1 kg (the main unit with consumables). When moving the machine to
ensure sufficient working space, take extra care to prevent back pain.
When moving it, always carry it by a team of two or more persons to avoid mishandling or injury. When lift-
ing this machine, use the handholds on both sides of the machine with two people.
4Safety Device
See that safety devices for preventing mechanical accidents, such as fuses, circuit breakers, and inter-
lock switches and those for protecting customers from injury, such as panels and covers, function prop-
erly. Modifications that hinder the function of any safety devices are strictly prohibited.

Chapter 1 Service Call Procedure
1.1 Before Starting the Servicing
1-2
5Installing and Removing Parts
Since the edge of parts and covers may be sharp, take care not to touch them. If the oil gets onto your
hand, wipe it off before getting on with the servicing. When pulling out parts or cables, do not yank but
pull gently and gradually.
Do not replace the lithium battery(Lithium metal battery) mounted on the ESS PWB alone.
NOTE
If the terminals of the lithium battery(Lithium metal battery) come in contact with other metal parts, leading
to short circuit, the battery may overheat, burst, or ignite. If the battery alone needs to be collected, the ter-
minals must be covered with adhesive insulation tape or by other means. When collecting the PWB or other
part with the lithium battery(Lithium metal battery) installed, carry the entire part in the packaging materials
(bag/box) for it.
6Specified Tools
Use the tools for the servicing procedure if any are specified.
7Cleaning the Toner and Developer
As the toner may cause a dust explosion, sweep the spilt toner into a waste container.
When using a cleaner to clean the remaining toner, be sure to use the FX standard toner-proof cleaner
and not a customer's cleaner.
Also, as the developer also contains toner, exercise the same caution during cleaning.
8Organic Solvents
When using an organic solvent such as the Drum Cleaner or Machine Cleaner, pay attention to the fol-
lowing:
zEnsure good ventilation in the room to prevent too much intake of the solvent.
zDo not use heated solvent.
zKeep away from fire.
Never throw, use, or store Drum Cleaner or Machine Cleaner in and around fire. Doing so may cause fire
due to flammability. Before disposing of a container of Drum Cleaner or Machine Cleaner, make sure that it
is completely depleted.
9Modifications
If any modifications are deemed necessary for the printer, submit an Application for Approval of Modifi-
cation prior to performing any work.

10 Harmful Laser
The customer or service personnel would not be exposed to any harmful laser during the usual copying
or scanning of documents. If your customer feels dazzled by the exposure lamp during normal opera-
tions of copying and scanning via the document glass, it is possible to shield light leakage by covering
the document glass except for the area used most commonly for copying and scanning.
11 Lithium battery
Lithium battery is used in the following component.
zPWBA ESS (PL18.1.2)
If not replaced properly , the battery can explode. Dispose of the old battery according to the instructions.
12 Other Safety Precautions
For safety, you should also pay attention to precautions other than the items 1 through 10 above. Fol-
low the instruction below to ensure greater safety during servicing.
