Hi all! I have an HP ScanJet 3200C parallel port scanner, which seems to work with the umax_pp backend. I am using Debian GNU/Linux (testing branch), which includes SANE version 1.0.19.
During a scan with $ scanimage -d umax_pp --format tiff --mode Color --resolution 300 > out.tiff I accidentally issued the following command: # scanimage --help --device-name umax_pp on another terminal and got the following errors: [umax_pp_low] PS2registerRead: found 0x20 expected 0x0 (umax_pp_low.c:7554) [umax_pp_low] sendData failed got 0xE8 instead of 0xC0 or 0xD0 (umax_pp_low.c:5564) [umax_pp_low] Blindly going on ..... [umax_pp_low] sendWord failed got 0xE8 instead of 0xC0 or 0xD0 (umax_pp_low.c:4711) [umax_pp_low] Blindly going on ..... [umax_pp_low] Unexpected reg19: 0xE8 instead of 0xC0 or 0xD0 (umax_pp_low.c:5611) [umax_pp_low] cmdSetDataBuffer(initbuf) failed ! (umax_pp_low.c:7812) scanimage: open of device umax_pp failed: Invalid argument Meanwhile, the terminal where the scan was going on spat out many other (more or less) similar errors, so I thought "oh no! I screwed my scan up! oh well, let's restart from scratch..." and killed the scanimage process with [Ctrl+C]. Worse! I got a great number of errors identical to [umax_pp_low] ppdev ioctl returned <Invalid argument> (umax_pp_low.c:4377) and pressed [Ctrl+C] again to stop them. At that point, the lamp was about halfway in the bed and there it stayed. I thought it would be brought back to the ready position at the next scan, so I restarted from scratch: $ scanimage -d umax_pp --format tiff --mode Color --resolution 300 > out.tiff The lamp was *not* reset to the ready position: it went on and, after some time, the scanner started to make a scary clicking noise. Ahhh! I unplugged the scanner. OK, after replugging the scanner, the lamp was not reset to the ready position; if I start another scan, I get the noise again and have to unplug the scanner. I searched the web, the SANE documentation, the SANE mailing lists, but failed to find a command to force the lamp to go back to the ready position! This scanner has no hardware power button. I already tried the procedure described at http://umax1220p.sourceforge.net/tips.html but unsuccessfully (the only difference is that I didn't use any printer). Can someone please help? How can I recover my currently unusable scanner? -- http://frx.netsons.org/doc/index.html#nanodocs The nano-document series is here! .....................................................
