Check for damage or obstructions that would prevent the tamper assembly fromoperating correctly. If necessary, install a new tamper assembly, PL 11.112 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, may stall and cause the machine toshutdown. The resulting shutdown can cause un-clearable jams in the finisher and thetray 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. Makesure the tray settings are correct.• Check the condition and tension of the front tamper drive belt. Tensioning is achieved by aspring 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 the IQ1 Image Quality Entry RAP.– Check the operation of the paddle roll, refer to 11-024-120, 11-025-120 Paddle RollFailure RAP.– Check the operation of the bin 1 upper level sensor, refer to 11-030-120, 11-334-120,11-335-120, 11-336-120 Bin 1 Movement Failure RAP.– Refer to the 11J-120 Mis-Registration in Stapled Sets and Non-Stapled Sets RAP.– Check the 1K LCSS PWB DIP switch settings, refer to 11E-120 1K LCSS PWB DIPSwitch Settings RAP.ProcedureNOTE: All 1K LCSS interlocks must be made to supply +24V to the motors.NOTE: In diagnostics, actuating any 1K LCSS sensor or switch can change the displayed stateon the UI. Make sure that the correct sensor or switch is tested.Enter dC330, codes 11-004 and 11-006 alternately. The rear tamper moves between thehome and inboard positions, Figure 1.Y NGo to Flag 3. Check the rear tamper motor, MOT11-004.Refer to:• 11F-120 1K LCSS PWB Damage RAP.• GP 10, How to Check a Motor.• P/J9, 1K LCSS PWB.• 11C-120 1K LCSS Power Distribution RAP.Repair or install new components as necessary:• Tamper assembly, PL 11.112 Item 1.• 1K LCSS PWB, PL 11.124 Item 1.Enter dC330 code 11-311.
