Service Call Procedure
1.1 Before Starting the Servicing
Version 1.1
1.1 Before Starting the Servicing
1.1.1 Safety
To prevent any accident that may occur during a maintenance service, any warning or any 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 discon-
nect the plug before starting the maintenance service. If the machine has to be switched ON, such
as when measuring the voltage, take extra care not to get an electrical shock.
2. Drive Area
Never inspect, clear or lubricate the drive area such as chain belts, chain wheel or gears during the
machine operation.
3. Heavy Parts
Always work in a pair when removing or installing heavy parts as shown below.
• One Tray Module (STM):11kg
4. Safety Device
See that safety devices for preventing mechanical accidents, such as fuses, circuit breakers, inter-
lock switches, etc., and those for protecting customers from injury, such as panels and covers, func-
tion properly. Modifications that hinder the function of any safety devices are strictly prohibited.
5. Installing and Removing Parts
The edge of parts and covers may be sharp, take care not to touch them. Be careful not to touch
those parts, and wipe off any oil that may have adhered to your fingers or hands before servicing.
When removing parts, cables, and etc. do not pull them out by force but remove them slowly.
6. Battery
Do not replace the battery by yourself.
• The battery may produce heat, blow out, or catch fire if the terminal comes in contact with the
other metal and short-circuits. If the battery alone is to be collected, be sure to cover the termi-
nal with a adhesive insulating tape, etc.
• If the battery is attached on the PWB or other part, put it in the packing material (bag or box) of
the part to be replaced for collection.
7. Specified Tools
Follow the instruction when a tool is specified.
8. Cleaning the Toner and Developer
As the toner can be explosive, sweep or brush the spilled toner into a container for collecting the
sweepings.
Clean away the remaining toner with a damp cloth or use an FX standard vacuum cleaner that is
toner-tolerant. Never use the customer’s vacuum cleaner.
Do the same when cleaning the Developer because it also contains some toner.
9. 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 inhalation of solvent fumes.
• Do not use heated solvent.
• Keep it away from fire.
• Wash your hands thoroughly after use.
10. Modifications to the Machine
Before altering the machine, submit the irregular use license application.
11. Harmful Laser
The customer or service personnel would not be exposed to any harmful laser during the usual
copying or scanning of documents. However, if a customer finds that the lamp that is used for
exposing documents is too bright when performing platen copy or scan, it is possible to block the
light from the platen glass by covering the portion of the platen document area that is usually not
used for copying or scanning documents.
12. Other Safety Precautions
For safety, you should also pay attention to precautions other than items 1 to 11 above. Follow the
instructions below to ensure greater safety during servicing.
