1.1 Before Starting Service
1.1.1Safety
To prevent any accident that may occur during maintenance service, any warning or any cau-
tion regarding the service 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 service. If the machine has to be
switched ON, such as when measuring a voltage, take extra care to avoid an electrical
shock.
2. Drive Area
Never inspect, clear or lubricate the drive components, such as chain belts, chain wheels
or gears, when the machine is in operation.
3. Heavy Parts
When removing or installing heavy parts, keep your back straight and lift with your legs.
Some parts should not be lifted by one person:
IOT (Platen): 31.5kg (requires 3 persons)
2 Tray Modules: 8.6kg (requires 2 persons)
Take extra care of your working posture to prevent backache.
4. Safety Devices
See that safety devices for preventing 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 Parts
The edges of parts and covers may be sharp, so 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 pulling out parts, cables, etc., do it gently. Do not use
excessive force.
6. Specified Tools
Follow the instructions when a particular tool is specified.
7. Cleaning Up Toner Spills
Since toner can be explosive, sweep or brush any spilled toner into a container to collect
it. To clean away the remaining toner using a vacuum cleaner, always use an FX standard
vacuum cleaner that is toner-tolerant. Never use the customer's vacuum cleaner.
8. Earthquake Preparedness Measures
If the customer requests earthquake proofing, an earthquake preparedness kit is avail-
able.
Check the Service Guide for more information on the earthquake preparedness kit.
9. Modifications to the Machine
Before altering the machine, submit an irregular use license application.
10. Other Safety Precautions
Follow the recommendations in WORKING PRACTICES FOR ENGINEERS issued by
FXAP EH&S (Environmental Health and Safety).

1.1.2Things to Note When Handling Customer Data
1. Handling of copied/printed customer data.
Before you bring back any sample for the purpose of investigation/analysis, always obtain
permission from the customer. Make sure you assure them that the data will not be used
for any other purpose.
2. Security-related NVM values that were changed during diagnostics.
If any security-related NVM values, such as polling, were set for test purposes, make sure
you restore them to their original values after the test.
3. Other things to note when handling customer data.
Follow the safety guidelines established within the OpCo and ensure that customer data
do not get compromised during service.
1.1.3 Other Precautions
To avoid performing wrong or unnecessary service, observe the following:
1. Reference Materials
Read all relevant service documentation, so that you can take a systematic approach.
2. Disassembling
Make sure to note the assembled condition of the machine before removing parts or dis-
assembling it.
3. Installation and Adjustment
After the installation or adjustment is complete, check that no parts or tools are left inside
the machine.
4. Handling of replaced parts and consumables
Make sure that any replaced parts or consumables, as well as the packaging materials,
are taken back to the Service Center.
Never discard the Drum/Toner Cartridges into a fire. Always keep them away from
open flames to prevent them from igniting and causing a fire.
NOTE: For separation and processing methods for replaced parts or consumables, refer
to Common Technical Information No. 2-138 for all machines.
• If you have replaced the following consumables, affix the "U-TAG" so that the recy-
clable parts will be handled appropriately.
a. Drum Cartridge
b. Toner Cartridge
• For recyclable parts, fill in the necessary items on the "U-TAG."
5. General Precautions
• Take care not to disturb the customer's daily work.
• Place any service-related trash into a trash bag and bring it to the service office.
• Clearly record the following information in the Machine Service Log:
– Details of the service call
– Parts and consumables replaced
