Carrier Sheet

hi,
is there a way to enable the carrier sheet without the interface ?
when i use :
this._twain32.ShowUI = true;
i can tick the carrier sheet mode and it scans perfectly,
but when i don't show the ui it blocks because the scanner detect it as multiple feed and stops as if the carrier sheet option was not ticked...

thanx

Edit :
with twain_32 Twacker

DG : DG_CONTROL
DAT : DAT_CUSTOMDSDATA
MSG : MSG_GET

If i modify the file with
CarrierSheetMode=1
And do a MSG_SET it works,
is there a way to set it with Saraff.Twain ?

Hello, neokeats.
You can read follow part of a documentation of the Saraff.Twain.NET: Strongly typed accessing to a capabilities, General (not strongly typed) accessing to a capabilities and Custom capability.
Also, you can read about follow capabilities in TWAIN Specification
  • CAP_FEEDERENABLED
  • CAP_AUTOFEED
  • CAP_FEEDPAGE
Try use follow code:
if(_twain32.Capabilities.FeederEnabled.IsSupported(TwQC.Set)) {
    _twain32.Capabilities.FeederEnabled.Set(true);
}
// or/and
if(_twain32.Capabilities.AutoFeed.IsSupported(TwQC.Set)) {
    _twain32.Capabilities.AutoFeed.Set(true);
}
// or/and
if(_twain32.Capabilities.FeedPage.IsSupported(TwQC.Set)) {
    _twain32.Capabilities.FeedPage.Set(true);
}
but I don't sure that is help to you, because your question related to specific scanner (ie that question don't related with a Saraff.Twain.NET). I advice send this question to a Support Service of your scanner.
