Paper Pick For Tray 1 - Xerox Phaser 8400 Service Manual

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
Spring loaded lift plate
