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.

Type:

IG_ISIS_TAG_TYPE_LONG

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.
