GENERAL PRECAUTIONS REGARDING THE SERVICE FOR
e-STUDIO5540C/6540C/6550C, e-STUDIO5560C/6560C/6570C
The installation and service shall be done by a qualified service
technician.
1. Transportation/Installation
- When transporting/installing the equipment, employ four persons and be sure to move it by the
casters while lifting the stoppers.
The equipment is quite heavy and weighs approximately 245 kg (540.12 lb) or 246 kg (542.33
lb), therefore pay full attention when handling it.
- Be sure not to hold the movable parts or units (e.g. the control panel, ADU or RADF) when
transporting the equipment.
- It is recommended to plug two power cables into two separate outlets. Be sure to use a
dedicated outlet with AC 115 V / 20 A <for NAC/NAD>, 220-240 V / 10 A <for ASU, ASD, ARD,
AUC/AUD, CND>, 220-240 V / 13 A <for <MJC/MJD> for its power source. If two power cables
are plugged into a single outlet, be sure to use at least a 20 A one.
- The equipment must be grounded for safety.
- Select a suitable place for installation. Avoid excessive heat, high humidity, dust, vibration and
direct sunlight.
- Provide proper ventilation since the equipment emits a slight amount of ozone.
- To insure adequate working space for the copying operation, keep a minimum clearance of 30
cm (11.8") on the left, 80 cm (32") on the right and 10 cm (4") on the rear.
- The equipment shall be installed near the socket outlet and shall be easily accessible.
- Be sure to fix and plug in the power cable securely after the installation so that no one trips over
it.
- If the unpacking place and where the equipment is to be installed differ, perform image quality
adjustment (automatic gamma adjustment) according to the temperature and humidity of the
place of installation and the paper to be used.
- When the equipment is used after the option is removed, be sure to install the parts or the covers
which have been taken off so that the inside of the equipment is not exposed.
2. General Precautions at Service
- Be sure to turn the power OFF and unplug the power cables during service (except for the
service should be done with the power turned ON).
- 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 a 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.
