Sensors Item No. Purpose Proof Tray Exit Sensor 1 Detects paper when it is fed out to the proof tray. Shift Tray Exit Sensor 3 Detects paper when it is fed out to the shift tray. Shift Tray Position Sensor 5 Detects when the shift tray is at the correct height to receive paper. Rear Booklet Tray Full Sensor 6 One of two sensors that the ma chine uses to determine when the booklet tray is full. Front Booklet Tray Full Sensor 7 One of two sensors that the ma chine uses to determine when the booklet tray is full. Proof Tray Full Sensor 8 Detects when the proof tray is full. Exit Guide Plate HP Sensor 9 Detects when the exit guide plate is at home position Entrance Sensor 10 Detects when paper comes into the finisher Staple Tray Exit Sensor 12 Detects paper leaving the bottom of the stapler Lower Limit Sensor 19 Detects when the shift tray has moved to its lowest possible position (the shift tray is full). Upper Cover Sensor 20 Detects when the upper cover is open Shift Motor HP Sensor 24 Detects when the side-to-side motion of the shift roller is at home position
Component Layout SM 35 B793 B793 Booklet Finisher Item No. Purpose Stopper S HP Sensor 28 Detects when the ‘stopper S’ me chanism is at home position. Stack Feed Out HP Sensor 29 Detects when the stack feed- out belt is at home position Staple Unit HP Sensor 30 Detects when the side-to-side motion of the stapler unit is at home position Jogger HP Sensor 34 Detects when the jogger unit is at home position Staple Tray Paper Sensor 35 Detects when paper is fed into the stapler tray Stapler Safety Sensor 37 Stops side-to-side movement of the stapler until stopper S and the stack feed-out pawl mechanisms are at home position, to prevent damage to the machine. Fold Unit Exit Sensor 38 1) Detects the folded edge of the stac k as it feeds out from the nip of the fold rollers so the fold feeds back into the nip, 2) when the folded booklet finally emerges from the nip of the fold rollers, detects the leading and trailing edge of the booklet to make sure that it feeds out correctly. Lower Clamp Roller HP Sensor 39 Detects when the lower clam p roller is at home position Fold Unit Entrance Sensor 41 Detects 1) the leading edge of the stack during booklet stapling, and 2) also used to signal an alarm if a paper is detected at the entrance of the fold unit when the copier is turned on. Bottom Fence HP Sensor 42 Detects when the bottom fence of the booklet folding mechanism is at home position Fold Cam HP Sensor 43 Along with the fold plate HP sens or, this sensor controls the movement of the fold plate. T he actuator mounted on the end of the roller that drives the folder plate forward and back makes three full rotations, i.e. the actuator passe s the sensor gap twice and stops on the 3rd rotation and reverses. This accounts for the left and right movement of the fold plate. Fold Plate HP Sensor 45 Along with the fold plate HP sens or this sensor controls the movement of the fold plate. The fold plate has arrived at the home position when the edge of the plat e enters the gap of this sensor. Punch Encoder Sensor 49 Controls the timing for activating t he punches, to punch holes in the paper at the correct position.

Shift Motor 23 Moves the shift tray from side to side. Stack Feed Out Motor 25 Controls the stack feed-out belt Jogger Motor 26 Controls the jogger in the stapler tray Upper Retraction Motor 27 Controls the ‘stopper S’ mechani sm. Also moves the upper clamp roller into contact and away from the stack of paper in the stapler tray. Upper 33 Rotates the upper clamp roller.
