Service Call Procedure Initial Issue
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 cau-
tion regarding the servicing must be strictly observed. Do not perform any hazardous opera-
tion.
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 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
Position your hip lower when removing or installing heavy parts.
4. Safety Device
See that safety devices for preventing mechanical accidents, such as fuses, circuit break-
ers, interlock switches, etc., and those for protecting customers from injury, such as pan-
els and covers, function 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. Specified Tools
Follow the instruction when a tool is specified.
7. Cleaning the Toner and Developer
As the toner can be explosive, sweep or brush the spilled toner into a container for collect-
ing the sweepings.
Clean away the remaining toner with a damp cloth or use a 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.
8. Organic Solvents
When using an organic solvent such as the Drum Cleaner or Machine Cleaner, pay atten-
tion 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.
9. 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 doc-
ument area that is usually not used for copying or scanning documents.
