Chapter 1 Service Call Procedure
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.
1. Power Supply
To prevent electrical shocks, burns, or injury, etc., be sure to switch OFF the machine and
disconnect the plug before starting the maintenance servicing. If the machine has to be switched
ON, such as when measuring the voltage, take extra care to prevent an electrical shock.
2. Drive Area
Never inspect or lubricate the drive area such as the gears during the machine operation.
3. Heavy Parts
The weight of the machine is 29.6kg. When moving the machine to ensure sufficient working
space, take extra care to prevent back pain.
4. Safety Device
See that safety devices for preventing mechanical accidents, such as fuses, circuit breakers,
interlock switches, etc., and those for protecting customers from injury, such as panels and
covers, function properly. Modifications that hinder the function of any safety devices are strictly
prohibited.
5. Installing and removing the parts
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 removing parts or cables, do not pull
them out by force but remove them slowly.
6. Specified Tools
Follow the instruction when a tool is specified.
7. Organic Solvents
When using an organic solvent such as the Drum Cleaner or Machine Cleaner, pay attention to
the following:
• Ensure good ventilation in the room to prevent too much intake of the solvent.
• Do not use heated solvent.
• Keep away from fire.
• Wash your hands throughly after use.
8. Cleaning 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.
9. Modifications
If any modifications are deemed necessary for the printer, submit an Application for Approval of
Modification prior to performing any work.
