procedure

1. Personal computer operating environment

•OS: Windows 95/98 (Desk-top/Note)

*If the version of the Windows 95 is OSR2 or earlier, download a patch from

Microsoft’s home page, and update the ISO.VDX.

• SCSI host adapter supporting ASPI

•This function is assured with the following SCSI host adapters:

PCI: AHA-2940 made by Adaptec

AHA-2910B made by Adaptec
PCMCIA: APA-1460 made by Adaptec
CardBus: APA-1480 made by Adaptec
ISA: AHA-1520B made by Adaptec

AHA-1510B made by Adaptec

•Driver software:

Ver.4.57 or a higher version is required for the ASPI driver software. If the version
is lower than Ver.4.57, the newest SCSI driver software and the ASPI driver
software should be downloaded from the Adaptec Co. Web site
(http://www.adaptec.com) and installed in the PC.

•SCSI cable

•Utility Software used by the ROM writing function of the ICU PWB.

•ICU Flash ROM PWB for writing new data.

2. Procedure
[1] Confirm whether the machine can start up using the Flash ROM which has been

installed in the machine.

[2] The machine is in the Sim26-44 mode.

In this Sim26-44, set the channel (A channel) where the SCSI cable will be
connected to ‘‘1’’ (SC PRINTER).
*If the AR-PB2 printer kit has already been used, since the channel setting has

already been completed, the above operation is not necessary. That is, the channel
where the printer kit has already been connected automatically becomes a channel
for the SCSI cable.

*If the version of the ICU ROM installed in the AR-280/285/335 is 2.xx, setting the

Sim26-44 is not necessary.

[3] Turn off the power and remove the cabinet of the Copier.

•Remove the rear cabinet, the flywheel, and the shield line guide.

•Remove the glass holder right, the table glass, and the dark box cover.

•Open the front cabinet , and remove the ROM cover from the frame cover A.

•When rewrite the flash ROM, can be operate without flash ROM PWB on the

OPE PWB and PCU PWB.
*1) When the flash ROM is rewritten using the ROM writer function described above,

it is essential that the flash ROM (program) of the ICU PWB is loaded to ICU
PWB socket-1. The targeted ROM is loaded to socket-2.
