That you are typing at an angle isn't relevant. The computer doesn't know or care.

TDATE is not set. That is why it is not working. You have to set it or inherit it from somewhere. It won't just appear because you want it to.

I must assume you are setting it somewhere else, or attempting to set it from somewhere else. This is the bit you haven't explained. You also haven't explained how you are running this program - manually, from cron, whatever.

NAME

       sane-sp15c - SANE backend for Fujitsu ScanPartner 15C flatbed scanner

DESCRIPTION

       The  sane-sp15c	library  implements  a	SANE  (Scanner Access Now Easy) backend which provides access to the Fujitsu flatbed scanners.	At
       present, the following scanner is known to work with these backend:

	      Vendor:  Model:		Rev:
	      -------- ---------------- -----
	      FCPA     ScanPartner 15C	1.01

       The ScanPartner 15C driver supports lineart (1-bit), halftone (1-bit), grayscale (4-bit and 8-bit), and color (3 x 8-bit) scanning.

       Other scanners in these families may work.  The ScanPartner 15C seems to be a repackaging of the ScanPartner 600C.  People  are	encouraged
       to try these driver with the other scanners and to contact the author with test results.

CONFIGURATION

       A  modest effort has been made to expose the standard options to the API.  This allows frontends such as xscanimage to set scanning region,
       resolution, bit-depth (and color), and enable the automatic document feeder.

LIMITATIONS

       Testing limited to a Linux 2.2.5 kernel
       Can't quite get the scan page/minute performance in ADF modes.  This may be due to limited system buffer size.

BUGS

       I'm sure there are plenty, and not too well hidden, but I haven't seen them yet.
       Both scanners claim to have separate control of resolution in X and Y directions.  I confess I haven't tested this yet.	I have found  that
       xsane doesn't even display this capability.
       Threshold settings on the SP15C don't seem to affect the results of lineart mode scans.
       It  might  be possible to merge these two drivers without much effort since the SP15C driver was derived from the M3096G driver.  They were
       split so as to keep the second driver development from breaking the working first driver.  Watch this space for changes.
