- Do not use an ozone generator near the MFP. Or, place any ozone generator as far away from the
MFP as possible.
2. General Precautions at Service
- Be sure to turn the power OFF and unplug the power cable during service (except for the service
should be done with the power turned ON).
- After the power cable is disconnected, an electric charge may remain in the boards of the
equipment. Therefore, be sure to disconnect or connect the connectors when about 1 minute (e.g.:
the time for taking off the rear cover) has passed after the power cable is disconnected.
- The fuse could be in the neutral. The mains supply shall be disconnected to de-energize the phase
conductors.
- Unplug the power cable and clean the area around the prongs of the plug and socket outlet once a
year or more. A fire may occur when dust lies on this area.
- When the parts are disassembled, reassembly is the reverse of disassembly unless otherwise
noted in this manual or other related documents. Be careful not to install small parts such as
screws, washers, pins, E-rings, star washers, harnesses in the wrong places.
- Basically, the equipment should not be operated with any parts removed or disassembled.
- The PC board must be stored in an anti-electrostatic bag and handled carefully using an antistatic
wrist strap since the ICs on it may be damaged due to static electricity.
Caution: Before using the antistatic wrist strap, unplug the power cable of the equipment and
make sure that there are no charged objects which are not insulated in the vicinity.
- e-STUDIO2515AC/3015AC/3515AC/4515AC/5015AC uses a laser diode. Avoid expose to laser
beam during service. Be sure not to expose your eyes to the laser beam. Do not insert reflecting
parts or tools such as a screwdriver on the laser beam path. Remove all reflecting metals such as
watches, rings, etc. before starting service.
- Be sure not to touch high-temperature sections such as the fuser unit, damp heater and areas
around them.
- Be sure not to touch high-voltage sections such as the chargers, transfer belt, 2nd transfer roller,
developer, high-voltage transformer and power supply unit. Especially, the board of these
components should not be touched since the electric charge may remain in the capacitors, etc. on
them even after the power is turned OFF.
- Make sure that the equipment will not operate before touching potentially dangerous places (e.g.
rotating/operating sections such as gears, belts pulleys, and fans).
- Be careful when removing the covers since there might be the parts with very sharp edges
underneath. Avoid exposing your eyes to laser beam in e-STUDIO2515AC/3015AC/3515AC/
4515AC/5015AC.
- When servicing the equipment with the power turned ON, be sure not to touch live sections and
rotating/operating sections.
- Use designated jigs and tools.
- Use recommended measuring instruments or equivalents.
- Return the equipment to the original state and check the operation when the service is finished.
- Be very careful to treat the touch panel gently and never hit it. Breaking the surface could cause
malfunctions.
- Do not leave plastic bags where children can get at them. This may cause an accident such as
suffocation if a child puts his/her head into a bag. Plastic bags of options or service parts must be
brought back.
- There is a risk of an electric shock or fire resulting from the damage to the harness covering or
conduction blockage. To avoid this, be sure to wire the harness in the same way as that before
disassembling when the equipment is assembled/disassembled.
3. General operations
- Check the procedures and perform them as described in the Service Manual.
- Make sure you do not lose your balance.
- Avoid exposure to your skin and wear protective gloves as needed.
4. Important Service Parts for Safety
- The breaker, door switch, fuse, thermostat, thermofuse, thermistor, batteries, IC-RAMs including
lithium batteries, etc. are particularly important for safety. Be sure to handle/install them properly. If
