Information about a scanner's feeder. 0x0503  1283

IG_ISIS_TAG_FEEDER lets an application determine whether the scanner has a flatbed, feeder, or both, lets the application determine whether or not the scanner can detect whether there is paper in the feeder or flatbed, lets the application determine whether the scanner needs to scan a page to determine whether or not a page is in the feeder or flatbed, and further lets the application determine whether the scanner can safely stop a ScanAhead batch before pages run out in the feeder.

Drivers:

All scanner drivers.

Values:

The values for IG_ISIS_TAG_FEEDER are returned in a bit field whose bits can be checked for the following values:

Value Defined Constant Meaning
0x00000001 IG_ISIS_FEEDER_FEED Scanner has a feeder.
0x00000002 IG_ISIS_FEEDER_FLAT Scanner has a flatbed
0x00020000 IG_ISIS_FEEDER_TELLFLAT Scanner can detect whether or not a page is on the flatbed. (Currently no scanners support this ability.)
0x00010000 IG_ISIS_FEEDER_TELLFEED Scanner can detect whether or not a page is in the feeder.
0x00040000 IG_ISIS_FEEDER_TELLSCAN Scanner can detect whether a page is loaded in the feeder only by committing a page. Whenever a page is committed, it should also be scanned. You must call IG_ISIS_run_zone to actually get the data from the page that is committed.
0x00080000 IG_ISIS_FEEDER_CENTERFEED Scanner can center a page in the feeder.
0x00100000 IG_ISIS_FEEDER_CENTERFLAT Scanner can detect whether or not a page is centered on the flatbed. (Currently no scanners support this ability.)
0x00200000 IG_ISIS_FEEDER_PAUSE Scanner can safely stop a ScanAhead batch in the middle of the batch and recover all pages left in the buffer. Use this value in conjunction with IG_ISIS_TAG_SCANAHEAD.
