[sane-devel] Canon N656U w. plustek driver: scanner makes strange noises

[Florian Leeber]

Dear All,

my old canon N656U has no support for 64bit windows drivers, so I
decided to connect it to the linux box in my home. Works without any
problems, but only for one page.

Scanning a consecutive page leads to a stuck scanner with the stepper
motor hitting hard on the 0 position obviously. So far it has not been
damaged I think, but time will tell... I tried to fix this with various
changes to the plustek.conf, but only to find out that output without
calibration is unusable. And also I do not manage to get calibration
saved properly.

What could be wrong with this device, it seems to be configured somehow
by the first scan run, and then it gives up completly on the second one.
