I have a pair of Paragon 1200 A3 Pro SCSI scanners, which are
Under WinXP, the Mustek-supplied TWAIN dialog shows a maximum y-axis
(length) of 429mm (or 16.9"). Screenshots for metric and imperial:
I have tested this (I placed a yardstick on the bed and scanned it)
and it does scan very close to 429mm.
The Mustek 1.0-138 backend included in 1.0.23 backends limits the
y-axis to 424mm. I have recently found that I need that extra 5mm ;)
There is a note in mustek.CHANGES:
* Released Mustek backend 1.0-137
* Reduced scan area of Mustek Paragon 1200 A3 Pro.
Removed warning message.
Increased support level to complete.
I assume that there was a good reason to do this, but I do not know
what it was.
[ Henning Meier-Geinitz kindly added the --lamp-off --dont-scan
options for me for the release after that one, and I use them quite a
bit, so using a backlevel backend is not a good option here. ]
a) Can the reason for reducing the scan area for this model be found?
b) Is it possible & reasonable to allow y-axis of 429.23mm for this
The relevant line in mustek.c is #1562 :
dev->y_range.max = SANE_FIX (424);
I'd like to try that with a value of 430.
I'm unable to compile this myself, as I do not have a setup that will
let me do this. I'm willing to be the tester.
