But hopefully more reliable. Here's two typical TWAIN conversations (with an
HP):

Do you have a feeder? -Yes
Can you tell me if the feeder is loaded? -Yes
Is the feeder loaded? -I don't know


Is the feeder enabled? -No
Please enable the feeder. -OK
Is the feeder enabled? -Yes
Please disable the feeder. -OK
Is the feeder enabled? -Yes
