Paper feed mechanism
When the drawer is inserted, the lever is triggered to lower the pick roller. The motor (2500-sheet tray elevator) drives
and raises the main tray until the paper is engaged with the pick roller. When the pick roller is engaged with the paper,
the sensor (2500-sheet tray main tray elevator limit) detects the uppermost sheet.
The motor (2500-sheet tray feed) drives the pick, feed, and separator rollers to pick up and feed a sheet of paper into
the vertical transport roller. The pick roller pushes the sheet to the feed roller and the separator roller makes sure that
only one sheet is fed at a time. As the paper passes though the transport roller, the sensor (2500-sheet tray transport)
detects it. The motor (2500-sheet tray transport) then drives the transport roller to transport the paper into the printer.
