GENERAL PRECAUTIONS REGARDING THE SERVICE FOR e-STUDIO165/167/205/207/237 AND GD-1220/1221

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

1) Transportation/Installation

- When transporting/installing the equipment, remove the drawer, employ two persons and be sure to hold the positions as shown in the figure. The equipment is quite heavy and weighs approximately 32.5 kg (71.65 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 110 V / 13.2 A, 115 V or 127 V / 12 A, 220-240 V or 240 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/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) 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 or do not use the parts not recommended by Toshiba TEC Corporation.

4) 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.

5) Disposal of the Equipment, Supplies, Packing Materials, Used Batteries and IC-RAMs

- Regarding the recovery and disposal of the equipment, supplies, packing materials, used batteries and IC-RAMs including lithium batteries, follow the relevant local regulations or rules.

Caution:

Dispose of used batteries and IC-RAMs including lithium batteries according to this manual.

Attention:

Se débarrasser de batteries et IC-RAMs usés y compris les batteries en lithium selon ce manuel.

SPECIFICATIONS AND OUTLINE OF SYSTEM

• Alternate number dialing It is possible to assign two facsimile telephone numbers to one abbreviated dial number or one touch dial key (one as the primary telephone number and the other as an alternate telephone number). The facsimile first dials the primary telephone number, then redials if the line is busy until the redialing limit count is reached. It will then begin to dial the alternate number. (Except for Relay/Mailbox/Confidential/Polling)

• Multi-address transmission function Transmissions of the same original to multiple addresses (up to 375 addresses) are possible using one operation sequence, in which preset abbreviated dial numbers (300), and one touch dial keys (75) can be used. When the multi-key is specified, key pad dialing of up to 100 locations, is also possible.

• Multi-polling reception Polling receptions from multiple remote parties (up to 375 parties) are possible using one operation sequence, in which preset abbreviated dial numbers (300), and one touch dial keys (75) can be used. When the multi-key is specified, key pad dialing of up to 100 locations, is also possible.

• Relay transmission request function The GD-1220/1221 can originate a relay transmission or serve as a relay station in relay transmission transactions.

• Secure RX Secure RX allows reception to memory to secure Originals during unattended periods. The user can select a specific time period and all day (24-hour) operation on selected days. The feature can be activated and deactivated by using a 4-digit security code.

• Memory transmission Allows you to dial the remote party while scanning the original in memory. The original page data is cleared as the sending of each page is completed. Therefore, the memory is utilized effectively for transmissions. A maximum of 100 jobs of memory transmission are possible.

• Public fax box An original can be reserved in image memory to be polled by remote stations multiple times. One of its merits is that any remote station (even one with a non-TOSHIBA facsimile) can poll such originals without a password.

• Program continuous polling By designating the starting interval, time, and day-of-week, an endless polling can be set. Once set, polling receptions are repeated at the same time on the designated day-of-week.

• Sub-address communication The GD-1220/1221 support communication applications using sub-address (SUB/SEP/PWD) commands conforming to ITU-T. Sub-address communication is possible by keypad dialing, one touch key dialing, and abbreviated dialing using the sub-address settings in Comm. Options.

• Security communication For transmissions, the facsimile checks if the telephone number of the remote party’s facsimile CSI matches the number dialed on the unit itself. If it matches, the transmission will start. For receptions, the facsimile checks if the telephone number of the remote party’s TSI matches any number assigned to an abbreviated dial number or one touch key. If it matches, the reception will start. Thus transmissions or receptions with any authorized party will be prevented at the earliest stage.

1 - 6

• Substitute reception into memory When there is no paper remaining in the drawer(s), when a recording paper jam occurs, the toner is empty, or printing is already in progress, the received data is stored into memory instead of being output to recording paper. When the trouble is corrected, or the active printing job is completed, the received data in memory will then be printed.

• Communication options If necessary, the function may be changed and options can be selected for page number, line monitoring, turnaround polling, ECM communication and security transmission, etc.

• Automatic dialing functions

- Dialing with a time designated

Transmitting a original to a designated party at a designated time.

- Redialing

When an automatic dialing has been performed and the destination party is busy, redialing will be repeated as many times as programmed with a certain time interval also programmed.

• Cover sheet function This facsimile has a facsimile cover sheet preparation feature built in, allowing the operator to enter the destination name, sender name at the time of the original transmission. This cover sheet also allows image data, such as a company logo, to be included.

• Account code By entering a different account code for each destination at the time of transmission, account codes will identify when, for whom, and to whom a particular facsimile message was sent.

• Department code Permits assigning 99 department codes to control access and track activity. These codes are set up beforehand, and must be used to access machine functions.

• Separator page function GD-1220/1221 have the feature which divide print jobs (received original) using separator page. Also the customer can program the specified paper drawer for this function.

• List output This allows the operator to print data stored in the memory (reservation list, preset dial number lists, function list, communication journal, transmission report, etc.).

• Power saver mode This feature turns off virtually all power to minimize power consumption. Only the sub-MPU remains operation sensing for ringing signals, original insertion, or activation of the [ENERGY SAVER] key.

• Sleep mode Reduces power consumption by cutting off power for the fuser during periods when printing is not expected. The fast warm up time ensures the printer section will be ready before a full page of image data can be received.

• Recovery transmission Originals that have gone through the redial count limit will not be cleared, but stored for a programmed period of time. Such originals can be recovered to be transmitted again.

• F-code mailbox/relay box communication Bulletin board F-code mailbox transmissions using ITU-T standard protocol is possible. Permitting confidential communications with any other similarity equipped facsimile made by TOSHIBA or some other company.

2.4 Recording paper selection algorithm and print algorithm

2.4.1 Recording paper selection algorithm

Capable of identifying the above-mentioned recording paper size of a received image, this machine prints on the recording paper of the same size as when sent, as a rule. If no recording paper of the identified size is not available, it selects recording paper for printing according to the set mode. The mode is set by using Func. 15 bit 3.

1) Automatic reduction mode (Func. 15 bit 3 = 0, Default) Selects recording paper on which the received document can be printed and prints on it.

2) Reduction OFF mode (Func. 15 bit 3 = 1) Selects recording paper on which the received document can be printed in a full size.

2.4.2 Print algorithm

A reception print image is basically printed on one page. Consequently, the algorithm of reception print is in the order of same size print, discard extra, vertical reduction print, and divided print. (Refer to the reception print flowchart.)
