7Place a jumper from pin 9 to pin 10 (ground). Using the printer’s power cord in place of the unit’s power cord, plug the printer’s power cord in the stacker unit, then into the wall outlet.
8With the power applied to the stacker unit, the exit roller motor
9Remove the jumper from pin 9 and pin 10.
10Lift the paper tray full actuator to enable photosensor OLLS to signal the output con- trol board to cause the elevator motor
11As the output tray guide reaches its lowest allowable position, photosensor OELS is enabled and signals the output control board to turn the elevator motor
12Releasing the paper tray full actuator then enables photosensor OULS to signal the output control board to turn the elevator
13As the output tray guide reaches its highest allowable position, the paper tray full actu- ator enables both photosensor OLLS and photosensor OULS, which in turn signal the output control board to turn the elevator motor
14Disconnect the power cord from the stacker, then place a jumper from pin 3 to pin 6 and a second jumper from pin 2 to pin 7.
15Reconnect the power cord, then (from the printer side of the unit) insert a folded piece of paper into the unit to trigger the actuator and enable photosensor OEPS. This will signal the output control board to turn the jogging rear motor
16After jogging has occurred, remove the piece of paper then reinsert it. This will again trigger the acturator and enable photosensor OEPS. This will signal the output control board to turn the jogging front motor
17The procedure is completed. Disconnect the power cord, remove the jumpers, then reinstall the unit into the printer.
