Paper Path and Paper Pick For paper picked from the document feeder, see the illustration on "Document Feeder Paper Path and Imaging" on page 2-6. Paper Pick for Tray 1 For Tray 1, the paper pick process is different than the pick process used by the other trays. To pick a sheet of paper, the Tray 1 solenoid is fired, and the drive gear rotates slightly to engage with the drive train. A bias force provided by the lift plate force against a cam causes the roller to rotate enough so the missing tooth gear engages the drive train. The pick roller rotates to pick the paper, and the separator pad assembly prevents multiple sheets from being picked by the pick roller. Key differences in the Tray 1 pick process include: ■ Lift plate force is optimized to support heavier paper ■ 100-sheet capacity ■ Pick roller creates the buckle for the deskew process ■ Pick roller drive disengages when the door is opened and closed ■ Pivoting separator pad to prevent it from binding Drive gear Cam Pick roller Spring loaded lift plate 2-18 Separator pad s8400-190 WorkCentre C2424 Service Manual
