Ricoh adc1scn Service Manual

SCANNER KIT

(Code: B359)

The B359 scanner kit option has a network interface, but there is
no SCSI interface.

Both hardware and software are completely different from the
A695 scanner option for the NAD30/40.

Therefore, the only comparison with the A695 in this manual is
the specification table, which compares the B359 with the A695.

The scanner controller contains image input and network interface circuits.
The image data from the BICU is compressed in the image input circuit, then the

data goes to the network through the network interface circuit.
Each circuit has a CPU and flash memory IC. The functions of each major

component are as follows.
