2.1.1. Mechanisms
1. Document Detection
The document sensor [A] detects when a document is placed in the ADF. The
fold-out extension [B] helps support longer documents.
2. Pick-up and Separation
When the document pick-up solenoid [A] is turned on, it allows the tray lifting
cam [B] to rotate. This allows the document plate [C] to be pushed up by a
spring under the plate. The document pick-up roller [D] feeds the top sheet of
the document into the scanner. The separation pad [E] prevents the docu-
ment pick-up roller from feeding more than one sheet at the time.
