Subject: Plustek 4831P scans binary mode incorrectly
From: Phoenix
Date: 05 Jun 2003 16:21:36 -0400

First the particulars...

Redhat 9 on an Intel PII board

using Redhat's kernel-2.4.20-13.9
using Redhat's sane-frontends-1.0.9-2
using sane-backends-1.0.9-5
using sane-backends-devel (no /backend directory, btw)


printer port setup to use EPP



built plustek-module-0 42 9

- it did not automatically create /dev/par* entries, they had to be
entered manually

- it does not automatically load the drivers after reboot, had to be
done manually (/sbin/modprobe /dev/pt drv



when using xsane the grayscale works as expected and stops the scanner
where indicated by prescan dialog

now if the scanning mode is switched to binary the results are like the
Star Wars introduction with the text "tilted" back. Also the overall
length is 2/3 the orignal with the rest being black. Finally the head
goes beyond the end boundary.

in short grayscale works, binary (b/w) does not

if you need any more information just ask... if test are required, I can
handle a walkthrough.
