Chapter 1 Introduction
1. Features
This machine has following features. B4 Document Scanning: It can scan and transmit B4-size (10 x 14) documents. High Capacity ADF with High-speed Scanning: It scans one A4-size document page in 1.2 seconds (line density 8 dot/mm x 3.85 line/mm) and stores it into memory. A high capacity supply of up to 50 sheets of documents is possible. High-speed Transmission: The TF861 uses a V.34 modem designed for 33,600 bps communications. The TF831 has a standard V.17 modem that is capable of 14,400 bps communications. The V.34 modem is an available option on the TF831. Multi-Access: By the multi-access facility, multiple processes can be performed in parallel using the memory, such as a transmission reservation during a reception, copying during memory transmission/reception, etc. The most appropriate combination of the high-speed reading capability and the multi-access facility enables to accelerate business works. Patterns of the multi-access are as follows: (1) Scan to Memory during a Memory Transmission (2) Scan to Memory during a Reception (3) Scan to Memory during a Substitute Reception (4) Copying during a Memory Transmission (5) Reception during Copying (6) Reception during Memory printing (7) Reception during a List printing (8) Scan to Memory during a Memory printing (9) Scan to Memory during a List printing Laser Recording on Plain Paper: Recording is performed on fixed sizes of paper - A4, Folio, Legal, B4 - using a laser-beam printer. Halftone System: Photographic images are clearly recorded by the 64 grayscales using the error diffusion method. High Resolution Mode: The TF861 can transmit and receive in UF Mode (406 x 391). The UF Receive Mode must be selected by the operator, and will reserve 96 pages of PIX Memory. The TF831 can transmit in SF Mode (203 x 391), but will receive Fine Mode (203 x 203) only.

SERVICE MANUAL
TF831/TF861
Recording Paper Cassette Unit: A 250 sheet cassette (A4, Folio, Legal or B4) is installed as a standard feature, 1 or 2 optional recording paper cassette units can be added to enable automatic paper feeding with a maximum of three recording paper cassettes. All recording paper cassettes use a convienient front loading design. Maximum recording paper capacity is 750 sheets, A4, Folio, Legal or B4. Image (PIX) Memory Communication Function: Picture data can be stored in the image (PIX) memory. For a delayed transmission, the picture data created by scanning documents is stored in the image memory, and will be transmitted at the designated time. Other memory functions include multi-address transmission, substitute reception, ECM communication, etc. The memory contents will be retained by a backup battery for up to 60 minutes if a power failure occurs. The TF861 has a standard memory of 4.73 Mb, and an available optional MEMORY PBA with a 4 Mb capacity. The TF831 has .73 Mb of standard memory, and will accept 2 optional MEMORY PBA's.

RX Memory Lock RX Memory Lock allows reception to memory to secure documents during unattended periods. The user can select the specific time period, and all day operation on selected days. The feature can be activated and deactivated by using a 4 digit security code. Mailbox Transmission/Reception Functions: (TOSHIBA Exclusive Mode) Using information boxes and fax boxes (with 3-digit box numbers), mail-sending and mail-receptions are possible. Memory Transmission: Allows you to dial the remote party while storing the document in memory. The document 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. Alternate Number Dialing: If two telephone numbers are preset to one abbreviated dial number or one-touch dial key (one as the ordinary telephone number and the other as an alternate telephone number). The unit first dials the ordinary telephone number, then redials if the line is busy until the redialing limit count is reached. Then it will begin to dial the alternate number. (Except for Relay/Mailbox/Confidential/Polling) Public Fax Box: It can be set as a polling document that can be polled by remote stations any number of times. One of its merits is that any remote station with a non-TOSHIBA fax unit can poll such documents 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: As the unit flexibly supports communication applications using sub-address (SUB/SEP/PWD) commands conforming to ITU-TU. Sub-address communication is possible by keypad dialing, one-touch key dialing, and abbreviated dialing with sub-address data added. Communication in High Resolution Mode: The Ulrta Fine (UF) high resolution mode of 16 x 15.4 dots/mm for the TF861 is possible for both document transmissions and receptions, which realizes the expression of each document with high fidelity. The UF reception mode is normally set to OFF. If the operator sets it to ON, 96 pages of PIX memory will be reserved. The UF transmit and receive modes are not available on the TF831. G3 Dual-line Simultaneous Communications: By installing an optional NCU PBA, the unit works as two fax units. Accordingly, two-line simultaneous communications are realized.

Security Communication: For transmissions, the unit 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 unit checks if the telephone number of the remote party's TSI matches any number assigned to an abbreviated dial number. If it matches, the reception will start. Thus transmissions or receptions with any unnecessary party will be prevented at the earliest stage. Substitute Reception into Memory: When there is no paper remaining in the recording paper cassette(s) of the unit, or when a recording paper jam occurs, or 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 being stored will then be printed. Communication Options: If necessary, the function may be changed and options can be selected for low-speed communication, transmission verification stamp activation, security transmission, line monitoring, ECM communication, and turnaround polling, etc. On-hook Dialing Function: Manual transmitting procedure is possible with the handset on-hooked (i.e., without lifting up the handset), using keypad dialing, abbreviated dialing, or one-touch key dialing. Automatic Dialing Functions (1) Dialing with a time designated It transmits a documents to a designated party at a designated time. (2) 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 interval length programmed. By pressing the [REDIAL] key and selecting the desired item in the menu, redialing of that item will immediately be performed. Cover Sheet Function: This fax unit has a fax cover sheet preparation feature built in, allowing the operator to enter the destination name, sender name at the time of the document transmission. This cover sheet also allows image data, such as a a company logo, to be included. Account Code: By entering a different account code for each destination at the time of transmission, it can clearly inform when, for whom, and for what that fax data was sent. Department Code: Permits 50 assigned department codes to control access and track activity. These codes are setup beforehand, and must be used to access machine functions.
