Abstract

Apparatus for feeding sheets of media to a media processor may include a take-away roller for engaging a first sheet of media. It may further include a first sensor for detecting a movement of the first sheet of media past the take-away roller. The apparatus may include a feed roller and a second sensor for detecting a movement of the first sheet of media past the feed roller. The apparatus may further include a second motor for driving the feed roller. Also, the apparatus may include an ejection roller, a third sensor for detecting the movement of the first sheet of media past the ejection roller, and a third motor for driving the ejection roller.

Claims (9)

1. A method for feeding media to a media processor, comprising:

engaging a first sheet of media using a take-away roller being driven by a first motor;

feeding the first sheet of media using a feed roller being driven by a second motor;

upon detecting a trailing edge of the first sheet of media past the take-away roller, engaging a second sheet of media;

upon detecting the trailing edge of the first sheet of media past the feed roller, feeding the second sheet of media; and

ejecting the first sheet of media using an ejection roller when the first sheet of media has been digitized.

2. The method of claim 1 , wherein the ejection roller is being driven at a different rate of rotation from a rate of rotation of the feed roller.

3. The method of claim 1 , further comprising:

sending a signal to a processor upon detection of the trailing edge of the first sheet of media past the take-away roller.
