Mechanical drive
In order for the print media to move through the paper path, there are several drive motors that supply the
mechanical power to the rollers discussed previously. The drives for these components are illustrated and
discussed in the following paragraphs.
Paper pick mechanism drive
When printing from Tray 1 or Tray 2, the paper pick motor drives the paper pick gears which causes the pick
roller to turn. During an MPF print, the paper pick motor drives the swing arm assembly for the MPF and causes
the MPF paper pick roller to turn.
