Paper feed
The pick roller pushes the topmost sheet to the feed roller. The separator roller makes sure that only one sheet is fed
at a time.
For tray 1, the feed roller moves the paper directly to the registration section. For trays 2 to 4, the paper is fed from
the feed roller to the transport rollers before going into the registration section.
The motor (paper feed) controls the pick, feed, and separator rollers. The motor (transport) drives the roller that moves
the paper upward to the registration section. The sensor (paper feed) and sensor (pass through) detect the position of
the paper.
