GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND SERVICE FOR e-STUDIO3511/4511, e-STUDIO281c/351c/451c, e-STUDIO350/352/450/452, e-STUDIO200L/202L/230/230L/232/280/280S/282/282S AND GD-1150/1151/1200/1201/1160/1260

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

1) Transportation/Installation

- Be sure to transport the equipment with the number of people given in the following table holding

the positions as indicated below. Pay full attention when handling it because it is quite heavy.

Model Weight Number of people

e-STUDIO3511/4511 Approx. 112 kg (246 lb.) 4

e-STUDIO281c/351c/451c Approx. 113 kg (249 lb.) 4

e-STUDIO350/352/450/452 Approx. 83 kg (182.98 lb.) 2

e-STUDIO200L/202L/230/ 230L/232/280/280S/282/282S

Approx. 75 kg (165.34 lb.) 2

e-STUDIO3511/4511/281c/351c/451c e-STUDIO350/352/450/452/

200L/202L/230/230L/232/280/280S/282/282S

- Be sure not to hold the movable parts or units (e.g. the control panel, ADU or RADF) when trans-

porting the equipment.

- Be sure to use a dedicated outlet with AC 110/13.2A, 115V or 127V/12A, 220V-240V or 240V/8A

for its power source.

- The equipment must be grounded for safety.

Never ground it to a gas pipe or a water pipe.

- Select a suitable place for installation.

Avoid excessive heat, high humidity, dust, vibration and direct sunlight.

- Also provide proper ventilation as 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”) in the rear.

- The socket-outlet shall be installed near the equipment and shall be easily accessible.

08/03

2) Service of Machines

- Basically, be sure to turn the main switch OFF and unplug the power cord during service.

- Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the

damp heater and their periphery.

- Be sure not to touch high-voltage sections such as the chargers, transfer belt, 2nd transfer roller,

developer, IH control circuit, high-voltage transformer, exposure lamp control inverter, inverter for the LCD backlight 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.

- Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fan, etc.

- Be careful when removing the covers since there might be the parts with very sharp edges

underneath.

- When servicing the machines with the main switch turned ON, be sure not to touch live sections

and rotating/operating sections. Avoid exposure to laser radiation.

- Use suitable measuring instruments and tools.

- Avoid exposure to laser radiation during servicing.

Avoid direct exposure to the beam. Do not insert tools, parts, etc. that are reflective into the path of the laser beam. Remove all watches, rings, bracelets, etc. that are reflective.

- Unplug the power cable and clean the area around the prongs of the plug once a year or more.

A fire may occur when dust lies on this area.

3) Main Service Parts for Safety

- The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important

for safety. Be sure to handle/install them properly. If these parts are shorted circuit and/or made their functions out, they may burn down, for instance, and may result in fatal accidents. Do not allow a short circuit to occur. Do not use the parts not recommended by Toshiba TEC Corporation.

4) Cautionary Labels

- During servicing, be sure to check the rating plate and the cautionary labels such as “Unplug the

power cord during service”, “Hot area”, “Laser warning label” etc. to see if there is any dirt on their surface and whether they are properly stuck to the equipment.

5) Disposition of Consumable Parts, Packing Materials, Used Batteries and RAM-ICs

- Regarding the recovery and disposal of the equipment, supplies, consumable parts, packing

materials, used batteries and RAM-ICs including lithium batteries, follow the relevant local regulations or rules.

6) When parts are disassembled, reassembly is basically the reverse of disassembly unless

otherwise noted in this manual or other related documents. Be careful not to reassemble small parts such as screws, washers, pins, E-rings, star washers in the wrong places.

7) Basically, the machine should not be operated with any parts removed or disassembled.

8) Precautions against Static Electricity

- The PC board must be stored in an anti-electrostatic bag and handled carefully using a wrist-

band, because the ICs on it may become damaged due to static electricity.

Caution: Before using the wristband, pull out the power cord plug of the equipment and make sure that there are no uninsulated charged objects in the vicinity.

Caution: Dispose of used batteries and RAM-ICs including lithium batteries according to this

manual.

Attention: Se débarrasser de batteries et RAM-ICs usés y compris les batteries en lithium selon

ce manuel.

Vorsicht: Entsorgung des gebrauchten Batterien und RAM-ICs (inklusive der Lithium-Batterie)

nach diessem Handbuch.

1.3 Features

• A3/LD scanning Scans data across A3/LD width and transmits in A3/LD actual size.

• High-speed scanning Inputs an A4/LT-size transmitted document in about 0.7 seconds (A4/LT document transmitted widthwise).

• High-speed transmission

33.6 Kbps high speed modem Toshiba original high-speed communication modes EX and HS JBIG encoding system

• Dual Access

- FAX transmission

There are two types of FAX transmission: Page-by-page direct transmission and memory transmission that all pages are stored in the memory before being transmitted.

- FAX reception

Basically, all pages are input in the memory before being output. This reduces the time that the FAX communication occupies the machine, making Dual Access between the copying/faxing and printing operation possible.

Namely, the followings are possible:

- Memory input during the memory transmission

- Memory input during the memory reception

- Copying during the memory transmission

- Reception during the copying

- Reception during the memory output

- Reception during the list output

• Laser printing on plain paper Printing is made on the standard size paper (A3/LD, B4/COMP, A4/LT/LG, A4-R/LT-R, B5, B5-R, FOLIO, and A5-R/ST-R) with the laser system.

•Gradation 256 tones, error diffusion method

• Memory communication function Image data can be stored in the HDD. In the delayed transmission, image data read from an original are stored in the memory, then sent when the specified time comes. Other memory functions: multi transmission, memory reception, ECM communication, etc.

• Smoothing The smoothing process is applied to the received images so that they are changed from 8 × 3.85, 8 × 7.7, 8 × 15.4 or 16 × 15.4 to 24 × 92.4 (equivalent to 600 × 2400dpi), then printed out.

• Editing function Duplex transmission and duplex printing are possible.

• FAX data file storage capacity 360 MB file storage capacity is added (for transmission: 240 MB, for reception: 120 MB)

Note: Note:

Note: For hard drivers, GB means 1 billion bytes.

SPECIFICATIONS AND OUTLINE OF SYSTEM

• Phone Book (1,000 addresses) Up to 1,000 addresses can be registered in the Phone Book using the large LCD control panel.

• Multi-address transmission function Data are sent to multiple addresses (400 destinations) in sequence in a single operation. There are three ways to choose/enter the address

- Choose from the Phone Book (up to 400 destinations)

- Direct dialing (up to 400 destinations)

- Mix operation (Phone Book, Direct dialing, Group destinations: up to 400 destinations)

• Memory reception function When the recording paper has run out or a paper jam has occurred, the memory receives and stores the data.

• Auto-dialing function

- Delayed dialing

Documents are transmitted automatically to the preset number at the preset time.

- Redialing

When the receiving side is busy during the automatic dialing, the machine keeps dialing at a fixed interval for a specified number of times.

• Receiving tone/completion tone Sound notifies that the reception of a FAX document or printing of a received document has been completed.

• List output The following data stored in the RAM can be printed out

- Phone book information

- Function list

- Transmission journal

- Reception journal

- Memory transmission report

- Power failure list etc.

• Power saver mode During hours in which the reception amount is small, the weekly timer works to shut off the main power and the heater power to save power consumption.

• Drawer selection It is possible to choose a drawer on to whose paper the received images are to be printed.

[Options]

• 2nd line One extra line can be added by installing the 2nd line unit (option).
