Allows the Application to set scan parameters depending upon the type of feeder.
If the Source has a general type of the feeder only, default scan parameters can depend upon the type of scan (general document or photo). In this case, negotiating this capability will allow the Source adjusting the settings accordingly. It is advised, therefore, that this capability be negotiated prior to the capabilities related to specific Source settings (like ICAP_ RESOLUTION, ICAP_PIXELTYPE, etc.) but after the other feeder-related capabilities (CAP_FEEDERENABLED, CAP_FEEDERLOADED).
MSG_GET provides a list of available feeder types. MSG_SET specifies which type of feeder to use.
Use this capability to report either the types of feeders available or (in the case where there is a general type feeder only) the scan types supported through the feeder.
