Check for damage or obstructions that would prevent the tamper assembly fromoperating correctly. If necessary, install a new tamper assembly, PL 11.16 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 themachine to shutdown. The resulting shutdown can cause un-clearable jams in the finisherand 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. Makesure the tray settings are correct.• Check the condition of the front tamper drive belt and that it is correctly tensioned. Ten-sioning 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 IQ1 Image Quality Entry RAP.– Check the operation of the paddle roll, refer to 11-024-110, 11-025-110 Paddle RollFailure RAP.– Check the operation of the bin 1 upper level sensor, refer to 11-030-110, 11-334-110,11-335-110, 11-336-110 Bin 1 Movement Failure RAP.– Refer to the 11J-110 Mis-Registration in Stapled Sets and Non-Stapled Sets RAP.– Check the 2K LCSS PWB DIP switch settings, refer to 11F-110 2K LCSS PWB DIPSwitch Settings RAP.ProcedureNOTE: All 2K LCSS interlocks must be made to supply +24V to the motors.NOTE: In diagnostics, actuating any 2K 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:• 11G-110 2K LCSS PWB Damage RAP.• GP 10, How to Check a Motor.• P/J312, 2K LCSS PWB.• 11D-110 2K LCSS Power Distribution RAP.Repair or install new components as necessary:• Tamper assembly, PL 11.16 Item 1.• 2K LCSS PWB, PL 11.26 Item 1.Enter dC330 code 11-311, actuate the rear tamper home sensor Q11-311. The displaychanges.Y NGo to Flag 1 and check Q11-311.Refer to:• 11G-110 2K LCSS PWB Damage RAP.• GP 11, How to Check a Sensor.• P/J312, 2K LCSS PWB.• 11D-110 2K LCSS Power Distribution RAP.Repair or install new components as necessary:• Rear tamper home sensor, PL 11.16 Item 3.• 2K LCSS PWB, PL 11.26 Item 1.NOTE: The away home position is used for short edge feed small paper. This saves unneces-sary rear tamper travel.Enter dC330, actuate the rear tamper away home sensor Q11-319. The display changes.Y NGo to Flag 2 and check Q11-319.Refer to:• 11G-110 2K LCSS PWB Damage RAP.• GP 11, How to Check a Sensor.• P/J312, 2K LCSS PWB.• 11D-110 2K LCSS Power Distribution RAP.Repair or install new components as necessary:• Rear tamper away home sensor, PL 11.16 Item 3.• 2K LCSS PWB, PL 11.26 Item 1.Perform SCP 6 Final Actions.
