1.7.2 Document Pick-Up Mechanism
The document pick-up mechanism consists of the Document Pressure
Pads, Document Stopper Guide Plate and Document Take-Up Roller.
When documents are loaded on the document feed table, they are pressed
against the Document Take-Up Roller by the Document Pressure Pads,
then they are taken up by the Document Take-Up Roller one by one,
commencing with the one from the bottom of the stack.
The Document Stopper Guide Plate determines the leading edge position of
the documents loaded in the ADF. It is normally in the raised position, and
is lowered at the start of pick-up motion.
