GENERAL PRECAUTIONS REGARDING THE SERVICE FOR e-STUDIO2007/2307/2507

The installation and service shall be done by a qualified service technician.

1. Transportation/Installation- When transporting/installing the equipment, employ two persons and be sure to hold the

positions as shown in the figure.The equipment is quite heavy and weighs approximately 28.5 kg (62.83 lb.), therefore pay full attention when handling it.

- Be sure not to hold the movable parts or units (e.g. the ADU or RADF) when transporting the equipment.

- Be sure to use a dedicated outlet with AC 120 V / 12 A, 220-240 V / 8A 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 accessible.- Be sure to fix and plug in the power cable securely after the installation so that no one trips over

it.- 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 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.

- 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 fuser unit, damp heater and areas around them.

- Be sure not to touch high-voltage sections such as the chargers, 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, 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.

- When servicing the equipment with the power turned ON, be sure not to touch live sections and rotating/operating sections. Avoid exposing your eyes to laser beam.

- 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.

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 these parts are short-circuited and their functions become ineffective, they may result in fatal accidents such as burnout. Do not allow a short-circuit and do not use the parts not recommended by Toshiba TEC Corporation.

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.

5. Cautionary Labels- During servicing, be sure to check the rating plate and cautionary labels such as Unplug the

power cable during service, CAUTION. HOT, CAUTION. HIGH VOLTAGE, CAUTION. LASER BEAM, etc. to see if there is any dirt on their surface and if they are properly stuck to the equipment.

3.4 Copy Process

3.4.1 General Description of Copying Process

Fig. 3-11

(1) Charging: Applies negative charge on the surface of the photoconductive drum.

(7) Separation: Separates paper with the toner image from the photoconductive drum.

(2) Data reading: The images on the original

are converted into electrical signals.(8) Fusing: Fuses the toner image onto the

paper by applying heat and pressure.

(3) Data writing: The electrical signals are converted into light signal (laser emission) which exposes the surface of the photoconductive drum.

(9) Cleaning: Scrapes off the residual toner from the drum.

(10) Discharging: Eliminates the residual

negative charge from the surface of the photoconductive drum.

(4) Development: Negatively-charged toner

adheres to the photoconductive drum and forms visible image.

(5) Transfer bias: Improves transfer efficiency.

(6) Transfer: Transfers the visible toner image

on the photoconductive drum onto paper.
