I finally got my scanner working with Ubuntu. It's a parallel-port Plustek 9636T which is supported by the Sane backend named plustek_pp:
http://www.sane-project.org/man/sane-plustek_pp.5.html This backend can operate either in "direct" mode (in user space), or as a kernel module. After getting poor results in direct mode I chose to build the module. With an awful lot of trial and error, I have found that it works nicely with the parallel port in EPP mode (which is recommended) EXCEPT that: (1) If I reboot or power down the machine while the scanner's lamp is turned on, then it no longer works, even if I power EVERYTHING off and back on again! There are no complaints from the software, but the scanner simply does not respond any more. (2) I can get it working again by going into the BIOS setup and switching the parallel port to SPP mode, changing the module's configuration to that mode, doing a scan, turning off the scanner's lamp, and then rebooting and changing it all back to EPP mode. How can this be? The only thing I can imagine is that it has something to do with the stepper motor position inside the scanner - where else might state information be preserved after a power-off? In case you are wondering, I don't want to stay in SPP mode because that causes scanning to become very slow. -- Rod _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
