Hi.
I've attached a patch for microtek.c which lets me use the ADF on my
ScanMaker IIG. A couple of notes:
1. The line where the paper length is calculated generated strange
numbers for me - my patch includes a change which fixes it, but I have
only tested it with my scanner :-(
2. My scanner gets this message:
scsi0 : weirdness
STATUS_REG: 00
BASR: 08
ICR: 00
MODE: 00
many times while the scan head is returning after a scan. Does anyone
know what causes this?
