GENERAL PRECAUTIONS REGARDING THE SERVICE FOR
e-STUDIO190F
The installation and service should be done by a qualified service technician.
1) Transportation/Installation
- When transporting/installing the equipment, be sure to hold the positions as shown in the figure.
- The equipment is quite heavy and weighs approximately 22.0 kg (48.50 lb), therefore pay full attention when
handling it.
- Be sure not to hold the movable parts or units when transporting the equipment.
- Be sure to use a dedicated outlet with AC 120 V / 8 A for its power source.
- 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 80 cm (32") 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.
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).
- 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 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 wristband since the ICs
on it may be damaged due to static electricity.
Caution: Before using the wristband, unplug the power cable of the equipment and
make sure that there are no charged objects which are not insulated in the
vicinity.
- Avoid expose to laser beam during service. This equipment uses a laser diode. 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 exposure lamp, fuser unit, damp heater and areas
around them.
- Be sure not to touch high-voltage sections such as the chargers, 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/oper-
ating sections such as gears, belts pulleys, fans and laser beam exit of the laser optical unit).
- Be careful when removing the covers since there might be the parts with very sharp edges underneath.
