Section: SANE Scanner Access Now Easy (5)
Updated: 08 Feb 2005
The sane-geniusvp2 backend supports EICI 091000 based parallel port flatbed scanners. This ASIC can be found on some Primax devices, and on the Genius ColorPage-Vivid Pro II scanner (which is actually a Primax OEM device).
The following scanner should work with this backend:
Model: ColorPage-Vivid Pro II
FCC ID: EMJFB308C
MODEL NO: FB601C
ASIC ID: 0xE1
Product ID: 0x06
ASIC: EICI 091000
AFE: Wolfson WM-8143-12
This section decribes the backend's configuration file entries. The file is located at:
For a proper setup, you will need at least this entry:
<DD CLASS="c1|device parport0:
PARALLEL PORT MODES
- The backend configuration file:
- The static library implementing this backend.:
- The shared library implementing this backend (present on systems that support dynamic loading).:
- This environment variable specifies the list of directories that may contain the configuration file. Under UNIX, the directories are separated by a colon (`:'), under OS/2, they are separated by a semi-colon (`;'). If this variable is not set, the configuration file is searched in two default directories: first, the current working directory (".") and then in /etc/sane.d. If the value of the environment variable ends with the directory separator character, then the default directories are searched after the explicitly specified directories. For example, setting SANE_CONFIG_DIR to "/tmp/config:" would result in directories "/tmp/config", ".", and "/etc/sane.d" being searched (in this order).:
- If the library was compiled with debug support enabled, this environment variable controls the debug level for this backend. Higher debug levels increase the verbosity of the output.
Example: export SANE_DEBUG_GENIUSVP2=10
To obtain debug messages from the backend, set this environment variable before calling your favorite frontend (e.g. xscanimage).
Example: export SANE_DEBUG_GENIUSVP2=10 ; xscanimage
KNOWN BUGS AND RESTRICTIONS
Scan may sometimes timeout due to the scanner's buffer not being filled after some reasonable time, and you get a truncated image. Just try scanning again and it should work.
Scans at high resolutions (e.g. 600 dpi.) may also be truncated if the selected scan area is too large. Just scan at lower (<= 300 dpi.) resolutions for now if you want a larger image.
The lamp carriage may sometimes go out of its maximum distance (297 mm), forcing the motor engine. You can detect this when the scanner produces a "strange" noise and the carriage is at its maximum distance from home. In this situation, turn off scanner power imediately, or you may risk damage your device. This seems to happen more often when scanning full pages at high resolutions.
