3.1.

Preventive Maintenance

Preventive maintenance is performed at specific intervals and consists of machine cleaning and parts
replacement. It is essential to perform these service activities properly and at the specified intervals for
customer satisfaction. The purpose of this service is to maintain machine performance and image quality.
- You should prepare the necessary PM kits, replacement parts, and tools for cleaning beforehand.
- After completing the preventive maintenance service, you should discard the used parts and
packaging, in accordance with local regulations and clean the surrounding area.
- Before servicing the equipment disconnect the power cord from the wall outlet.
- Before using solvents such as IPA (Isopropyl alcohol), put on rubber gloves and eye protection.
1. Timing
- Perform the preventive maintenance service in accordance with the chart of preventive maintenance
areas listed in the service manual.
2. Cleaning of Rollers
- Rollers should be cleaned with water and cloth.
- Use of IPA (Isopropyl alcohol) should be used sparingly.
3. Precautions for Disassembly, and Adjustment
Caution:
Turn the Main Power Switch on the Back, and the Power Switch on the Left Side of the
machine to the OFF position, and then unplug the AC Power Cord before disassembling the
machine.
- After taking the unit apart, do not attempt to operate the machine.
- When operating the machine with covers removed, be careful to avoid clothing being caught by
moving components.
- While electricity is applied, the connectors of any PC Board must not be connected or disconnected.
- Use of a vacuum cleaner for the cleaning of the TDC sensor could cause electrostatic damage,
therefore, use a blower brush or cotton swab for the cleaning of these parts. Before vacuuming the
developer unit remove the TDC sensor.
- When handling the drum, the precautions listed in section 3.4. should be followed.
- Make sure to use the correct screw sizes.
- Use toothed lock washers for the installation of ground wires to ensure electrical continuity.
- To re-assemble, reverse the sequence of disassembly, unless otherwise specified.
- Blown fuses should only be replaced with fuses of the same specified rating.
4. Precautions for Handling Lasers
The laser optical system employed by this photocopier is completely sealed by a protective housing
and an external cover. Therefore, the laser beam will not stray or leak during photocopier operation.
However, when servicing the photocopier, take the following precautions:
1. Do not insert into the path of the laser, any screwdrivers or other tools that have high reflectance
properties.
2. Before servicing the photocopier, take off any watches, rings, or other metallic objects that you may
be wearing. (This is to avoid the danger of the laser entering the eye by reflecting off the metallic
objects being worn.)
Since the laser beam cannot be seen with the naked eye, please follow the above precautions for
maximum safety.
5. Precautions for Maintenance, and Disposal (Data Security)
1. The Service Mode Password is essential to maintaining the security of the machine.
Service technicians must change the factory default password using the Service Mode "F7-09:
Service Mode Password", record the new password and store it in a safe place out of the reach of
others. (Refer to the Service Manual Section 5.1.6.)
