I have a pair of Paragon 1200 A3 Pro SCSI scanners, which are large-format.
Under WinXP, the Mustek-supplied TWAIN dialog shows a maximum y-axis (length) of 429mm (or 16.9"). Screenshots for metric and imperial: http://asavage.dyndns.org/ftp/hosting/SANE/TWAIN_01b.jpg http://asavage.dyndns.org/ftp/hosting/SANE/TWAIN_02b.jpg 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: 2004-06-08 * 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? Regardless: b) Is it possible & reasonable to allow y-axis of 429.23mm for this model? 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. -- Regards, Duvall, Wash. Al S. http://nissandiesel.dyndns.org
