- Ricoh Scanners
- RICOH.SYS
- ------------------------------------------------------------------------------
-
- You use the RICOH.SYS scanner driver with the Ricoh IS-11,
- Ricoh RS-312, and Ricoh RS-320 scanners. The RICOH.SYS driver
- works only with the ISI-8 scanner interface board.
-
- These scanners require a second device driver, available
- from Ricoh, called SCN8.COM. SCN8.COM accesses the port
- address for these scanners. Copy SCN8.COM to your system
- and add it to your CONFIG.SYS. SCN8.COM must appear before
- RICOH.SYS in your CONFIG.SYS.
-
- SCN8.COM creates a DOS device called "SCANNER." If you have
- other files or directories called SCANNER, they may be
- unavailable from DOS while the SCN8.COM program is installed.
- You should rename any files or directories with the name SCANNER.
-
- To add the device driver and SCN8.COM to your CONFIG.SYS, use
- a text editor to type the entry as it appears below. Be sure to
- include a path if the scanner driver is not in your root directory.
- Remember to include additional parameters when necessary.
-
- CONFIG.SYS entries:
-
- device = SCN8.COM
- device = RICOH.SYS /Sx /Rx
-
- where...
- /S0 for RS320 (default)
- /S1 for RS312
- /S1C for RS312 300dpi only (do not use a 'R' switch)
- /S2 for IS11
-
- when RS320 is selected...
- /R1 for 360, 300, 200, 150, and 100 dpi (default)
- /R2 for 345, 270, 255, 195, and 135 dpi
- /R3 for 315, 240, 210, 180, and 120 dpi
- /R4 for 285, 225, 165, 160, and 100 dpi
-
- when RS312 is selected...
- /R1 for 300, 200, 150, 120, and 100 dpi (default)
- /R2 for 240, 180, 150, 120, and 100 dpi
-
- when IS11 is selected...
- /R1 for 450, 400, 300, 200, and 100 dpi (default)
- /R2 for 435, 345, 240, 165, and 120 dpi
- /R3 for 420, 315, 225, 150, and 135 dpi
- /R4 for 390, 375, 270, 195, and 180 dpi
- /R5 for 360, 285, 255, 210, and 100 dpi
-
- NOTE: Either switch may be omitted without affecting the use
- of the other. BUT, when both are used, the 'S' switch
- MUST precede the 'R' switch, or neither will be recognized.
