RICOH RS232 PC–FAX EXPANDER TYPE 100 SERVICE MANUAL

1. INTRODUCTION

The Ricoh RS-232 PC–FAX Expander Type 100 is a service-installed fax option kit that will add an RS-232 serial interface—the Digital Interface Unit (DIU)—to the Ricoh FAX2400L, FAX2700L, and FAX3700L fax machines. With a serial transmission cable provided by the customer, the DIU is connected from the fax machine to a personal computer serial communication port. When installed, it will allow the PC to use the fax machine to

TRANSMIT AND RECEIVE fax messages directly from the PC through the

FAX machine.

SCAN documents, from the FAX machine into the PC PRINT fax messages from the PC through the FAX machine.

NOTE: The PC–FAX Expander Type 100 will operate with the 300 dpi Type 100 Printer Interface option for improved print quality.

The option's new software will load a new User Parameter switch (14) to the fax machine's parameter switches; it will add a new fax function (16) to enable scanning from the fax machine to PC, and function (24) to reduce time the fax is occupied with redials.

The option kit includes

FIRMWARE that modifies the fax machine's System flash ROM, A FAXING APPLICATION (Ricoh Bitware by Cheyenne) to be installed in the

PC.

A TWAIN DRIVER (Ricoh CFM TWAIN) to be installed in the PC.

Not included in the option are

The RS-232 serial cable used to connect the fax machine with the PC. A null modem adapter. (The null modem function is built into the DIU.)

Foreign Language Capability

The standard base fax machine comes with multi-lingual capability. Space considerations for the PC-Fax Expander has forced the elimination of this ability. After the PC-Fax Expander option is installed, the fax machine will not display instructions or print reports in French or Spanish. Function 93, language selection, will not be available.

FAX WITH PC-FAX EXPANDER

RICOH RS232 PC–FAX EXPANDER TYPE 100 SERVICE MANUAL

The DIU is (Digital Interface Unit) connected directly to the fax machine's data/address bus. The signal flow is controlled by two settings: the PC modem setup, and a special PCFE Type 100 fax bitswitch, User Parameter Switch 14. The PCFE Type 100 is compatible with Class 1 and Class 2 communication modes. Either mode can be selected for PC modem setup.

When the PC modem is set for Class 1, the Parameter switch is inactive. When the PC modem is set for Class 2, The User Parameter switch governs the data flow through the fax machine. It can also restrict the sending the fax machine's TTI.

4.1 DIRECT TRANSMISSION Class 1 ALL Class 1 transmissions are direct transmissions, bypassing the fax

machine processes, such as data compression and ECM/SAF memory. The PC–FAX Expander will not use the communication protocol signals that are originated by a PC faxing application. The data that is faxed by the PC is sent directly through the fax machine modem. The resources of the fax machine are not used, except for it's modem.

The communications have the characteristics provided by the PC faxing application. For example, faxing applications use MH compression and the MMR technique resident in the fax machine DCR (Data Compression and Reconstructor) will not be available.

Class 1 communications will allow ECM and Binary File Transfer (BFT) from PC application files to remote devices capable of receiving such files.

Class 2 Direct Class 2 transmissions will bypass the fax machine DCR and

memory functions and use the fax machine as an external faxmodem. In Class 2, the fax machine modem originates and exchanges protocols with remote devices, resulting in more reliable communication than Class

1. Class 2 communications do not permit BFT.

MODEM

RICOH RS232 PC–FAX EXPANDER TYPE 100 SERVICE MANUAL

Class 1 and Class 2 receptions use the PCFE Type 100 fax machine as an external faxmodem. The process is similar to direct transmission—the fax data route will bypass the fax machine processes, such as DCR and ECM/SAF memory.

Signal flow is controlled by:

selecting Class 1 or Class 2 at the PC modem setup and the bitswitch settings of User Parameter Switch 14.

To receive a direct communication, the PC power must be on, and the PC faxing application must be running and set for Auto Receive.

Class 1 ALL Class 1 receptions are direct receptions. The fax machine DCR

and ECM/SAF processes are bypassed, UNLESS the PC is unable to receive. Then, the incoming fax data will be sent to the DCR as in a normal G3 reception. The message will then be reconstructed and printed by the fax machine.

The PC–FAX Expander will pass on the communication protocol signals that were originated by a PC faxing application.

Class 2 Direct Class 2 receptions will not use the fax machine DCR and memory

functions, UNLESS the PC is unable to receive. Then, the incoming message is printed by the fax machine.

The fax machine is used as an external faxmodem, exchanging protocols with remote devices.
