update: i hard-set the gamma byte (0x29) to 0x80, and the paper byte (0x35) to 0xC0, and then forced the lines:
set_WD_paper_width_X (buffer, s->page_width); set_WD_paper_length_Y (buffer, s->page_height); to always run, and the scanner runs. but now, the output images from the program 'scanadf' are truncated. any ideas? allan On Wed, 26 Mar 2003, m. allan noah wrote: > just got a Fujitsu fi-4120C scanner. was previously using an M3091DCd. i > am running latest cvs snapshot. i use the scsi port, not usb. i get the > following error: > > [fujitsu] Window set > [fujitsu] 000: 00 00 01 2c 01 2c 00 00 00 00 00 00 00 00 00 00 > [fujitsu] 016: 25 00 00 00 24 e8 00 80 00 00 01 00 00 00 00 00 > [fujitsu] 032: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 a0 > [fujitsu] 048: 20 00 00 00 00 84 00 00 00 00 00 00 00 00 00 00 > [fujitsu] <cmd< > [fujitsu] 000: 24 00 00 00 00 00 00 00 48 00 00 00 00 00 00 00 > [fujitsu] 016: 00 40 00 00 01 2c 01 2c 00 00 00 00 00 00 00 00 > [fujitsu] 032: 00 00 25 00 00 00 24 e8 00 80 00 00 01 00 00 00 > [fujitsu] 048: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 > [fujitsu] 064: 00 a0 20 00 00 00 00 84 00 00 00 00 00 00 00 00 > [fujitsu] 080: 00 00 > [fujitsu] 5/38/0: Invalid field in parm list > [fujitsu] offending byte is 49.
