The following service tools have been de velo pe d to chan ge ROM a nd RAM dat a fo r F/ L serie s machines.

1. RRW ( Remote ROM Writer )

Software in ROM can be changed remo te ly sin ce a Flash ROM is use d fo r F/L series machines. The RRW is a software package that runs in a Personal Computer with an external class 1 modem of a type recommended by Ricoh and can change the RO M dat a in F/L series machines through th e te lephone network.

Please contact Ricoh to order t he RRW. It will be rele ase d in May 1995 .

2. RDS Version 2.0

The new RDS Version 2.0 runs in a Personal Comp ut er with an external class 1 modem of a type recommended by Ricoh and can change RAM data such as Quick Tel. Numb ers,

Bit switches, RTI etc. ... in remo te fax mach ines made by Ricoh through the tele phon e network.

This RDS can also change ROM data in Ricoh made fa x machines that use flash ROMs. Please contact Ricoh to order RDS Versio n 2.0. It will be rele ase d in Jun e 1995 .

3. Flash ROM/SRAM Copy Tool ( P/N: H5159100 ) This is an interface card between the FCE inside the machin e an d an FCE outside the machine.

There are three purposes for this tool.

[1] Transferring user data in the RAM su ch as Qu ick Tel. Numb ers, Bit Switches, etc. ...

in an FCE removed from a defective machine to a new FCE installed in the machine. [2] Updating the ROM inside the machine from an FCE or EPROM Board outside the machine

without replacing the ROM. [3] Copying the ROM data inside the machine into the ROM on an FCE outside the machine.

This tool is available at the Spare Parts Center.

SUBJECT: Introduction of the New Tools for ROM/RAM Data Change

4. EPROM Board

This is a tool for updating the ROM inside the machine without repla cing the ROM. Programmed EPROM(s) can be installed on the EPROM board .

The EPROM Board is connected to the Flash ROM/SRAM Copy Tool and the data in the EPROM is transferred to the Flash RO M inside the machine through the Flash ROM/SRA M Copy Tool.

Please contact Ricoh to order EPROM Board.

Note: In the LSO, the NCU Cover, Front Cover and Left Cover have to be removed to set the Flash ROM/SRAM Copy Tool.

The Flash ROM / SRAM Copy Tool [A] is inserte d int o the memory card slot [D], then the FCE [B] or EPROM Board [C] with new software is connected to the opposite side of the tool.

ROM Data Download

This function copies soft ware from an exte rnal medium to the Flash ROM on the machine’s FCE. The external medium for the new sof twa re can be an FCE [B] or an EP ROM Board [C].

ROM Data Upload

This function copies the soft ware from the machine’s built-in FCE to an ext ern al FCE [B ]. This function does not work with an EPRO M Boa rd [C] .

SRAM Data Download

This function copies all the dat a stored in the SRAM on an external FCE [B] to the ma chin e’s FCE. Use this after replacing a damaged FCE to save any previous settings that were programmed in the damaged FCE.

Note:

1) SRAM data upload is not available .

2) Refer to the service manual for the opera tio n pro cedure.

3) The blank EPROM (P/N H082 7110) wh ich is 150 ns or 120n s spee d fo r the CFO can be used for the FX4. However, it cannot be used fo r t he FX6 an d the LSO. The blank EPROM (P/N 19050020) which is 100ns spee d can be used fo r the FX6, the LSO, and the FX4.

In this case, it is assumed tha t th e pa pe r size senso r is out of position because of tra nsp ortation damage.

The drop test was checked up to a heig ht of 80 cm (our sp ecif ication) but no problem was fou nd . If it is dropped from a heig ht excee ding 80 cm, it is considered that the problem may occur

Problem:

Auto Service Call 0-05 (Fusing Unit Failure; see page 6-26 of the Service Man ual )

Cause:

There are two switches, for the 5V line and th e 24V line , in th e Safe ty Switch (Index no.133 on page 1-16 of Parts Catalog). If the Top Cover or Front Cover is not closed completely, there is a possibility that the 5V switch will turn on but the 24V switch will not. In this case, "Cover Closed" is detected but the fusing lamp is n ot turn ed on, and this is the cause of the Auto Service Call.

Action Taken:

1) Remove the Right Cover.

2) Disconnect the 5V lines and th e 24 V lines.

3) Remove the Safety Switch.

4) Turn the Safety Switch 180 degrees.

The FCE2 (Facsimile Control Engine) conta ins the FCIP (Facsimile Control and Image Processor), DRAM, SRAM, System ROM, R14 4E FXL mode m, and vide o processing memory, and controls the entire syste m through the FDU (Facs im il e Dri ver Unit).

There are two cpus in the mach ine: the main cpu (FCIP) on the FCE an d the energy saver cpu on the FDU. In energy saver mode, th e main CPU swit che s off and the energy save r CP U take s over.

The FCIP consists of the fo llowing component blocks:

• RU8 CPU - Main CPU • MDM - Modem

• LIF- Laser Interface • DMAC - DMA Controller

• PRIF - Printer Interface • DIP - Digital Image Processor

• DCR - Data Compression and Reconstruct ion

The modem inside the FCIP is used for V.29, V27.te r, and V.21 com muni ca tions . In addition, the Rockwell R144 EFX L modem is used for V.17 and V.33 communications.

The 1.5 MB DRAM contains the SAF memory, ECM buffer memor y, work area, and page memory. The SAF memory can be extended by 2 or 4 Mbytes with an IC car d. A 512 kB (4 Mbit) flash ROM is used for the system ROM. Software in this ROM can be rewritten from the IC card slot or by RDS. Another 128 kB mask ROM contai ns LCD wording data.

Immediate Transmission:

Scanned data from the contact imag e sen sor pa sses to the DI P blo ck in the FCIP. Aft er analog/digital vide o pro cessin g, the DCR block compresses the data for tra nsmission. The compressed data then passe s eith er to the FIFO memo ry o r to th e ECM memo ry b ef ore it is sent to the telephone line through the modem. If a data rate of 12,000 or 14,400 bps is used, the data passes through the E14 4E FL Mod em.

Memory Transmission:

First, the scanned data is sto red in the SAF memo ry aft er compression in the DCR block. At the time for transmission, the DCR block decompre sses th e data from the SAF me mory, then compresses it again after ha nd sha king with the other termin al is don e. The compressed data then passes either to the FIFO memory or to the ECM memory, before it is sent to the telephone line t hro ug h the modem.

Data from the line passe s to th e modem through the NCU and hyb rid IC. Aft er the modem demodulates the da ta , the decompressed data passe s to th e DCR b lock, through either the FIFO or the ECM memory, where th e da ta is decompressed to raster image dat a. At the same time, the compressed data passes to the SAF memo ry as a backu p in case of mech an ical problems during printing (substitute reception).

The raster image data is th en passe d to the pag e memo ry f or prin ting. After a page of data has been stored in the page memory, the data is sent to the LDDR thro ug h the LIF block.
