Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
WARNING
Take care not to topple the LCSS. The LCSS is unstable when undocked from the
machine. Do not show the customer how to undock the LCSS.
• Check for damage or obstructions that would prevent the tamper assembly from operating
correctly. If necessary, install a new tamper assembly,
PL 12.45 Item 1 .
• Jams can be caused by removing prints from bin 1 before the machine has finished print-
ing. If the tampers are touched while they are moving, they may stall and cause the
machine to shutdown. The resulting shutdown can cause un-clearable jams in the finisher
and the tray 3 and tray 4 to paper path interface.
• Jams can also be caused if the tray settings do not match the paper in the trays. Make
sure the tray settings are correct.
• Check the condition and the tension of the front tamper drive belt. Tensioning is achieved
by a spring on the motor, the motor should be free to move.
• If there is a large jam of paper above bin 1 that has obstructed the tampers, this has prob-
ably been caused by poorly stacked sets failing to actuate the bin 1 upper level sensor.
Perform the following:
– Check the paper for defects that could degrade the tamping operation e.g. curl,
paper condition, buckling or paper type. Refer to
IQ 1 Image Quality Entry RAP.
– Check the operation of the paddle roll, refer to 12-024-00-110, 12-025-00-110 Pad-
dle Roll Failure RAP.
– Check the operation of the bin 1 upper level sensor, refer to 12-462-00-110 Bin 1
Movement Failure RAP.
– Refer to the 12J-110 Mis-Registration in Stapled Sets and Non-Stapled Sets RAP.
– Check the LCSS PWB DIP switch settings, refer to 12F-110 LCSS PWB DIP Switch
Settings RAP.
Procedure
NOTE: All LCSS interlocks must be made to 24V to the motors.
NOTE: With reference to WD 12.3 component control codes;
Code 12-226 moves the front tamper to the home position.
Code 12-228 moves the front tamper inboard (away from home).
Code 12-230 moves both tampers to the A4 LEF position.
Code 12-231 moves both tampers to the 8.5 x 11 LEF position.
Code 12-232 Cycles the tampers in and out until time-out.
