Status Indicator RAPs
11-050-110, 11-360-110 Staple Head Operation Failure RAP
11-050-110 The staple head fails to cycle.
11-360-110 The staple head is not at the home position.
NOTE: The home position is with the jaws of the staple head fully open.
NOTE: Staple head operation faults can be caused by offline stapling failures. The user may
be attempting to staple a set that exceeds the number of sheets/weight capacity. There may
also be an offline stapling problem, refer to 11A-110 Offline Stapling Fault RAP.
WARNING
Take care not to topple the LCSS.
The LCSS is unstable when un-docked from the machine.
Do not show the customer how to un-dock the LCSS.
Initial Actions
Switch off the machine, then switch on the machine, GP 14.
Check the following:
• Figure 1, the spring and cam are correctly located.
• Figure 1, the switch support bracket is correctly located.
• Figure 1, the safety gate switch connector is fully seated on both sides of the frame.
• The 2K LCSS PWB DIP switch settings, refer to 11F-110 2K LCSS PWB DIP Switch Set-
tings RAP.
• Figure 1, the staple head unit is correctly installed.
NOTE: Figure 1 shows the switch cam in the auto stapling position. To enable offline stapling,
the paddle motor is run in the reverse direction to lower the safety gate, this rotates the switch
cam in a counterclockwise direction, actuating the safety gate switch.
Procedure
NOTE: After repairing the fault using this RAP, switch off the machine, then switch on the
machine, GP 14, to enable operation of the staple head.
NOTE: All 2K LCSS interlocks must be made to 24V to the motors.
NOTE: In diagnostics, actuating any 2K LCSS sensor or switch can change the displayed state
on the UI. Make sure that the correct sensor or switch is tested.
Enter dC330, code 11-050 to cycle the staple head once, and 11-051 to reverse the staple
head to the home position. The staple head operates as expected.

Repair the wiring.
Go to Flag 3 and check the SU1 safety gate switch, S11-365. Refer to:
• 11G-110 2K LCSS PWB Damage RAP.
• GP 13, How to Check a Switch.
• Figure 1.
• P/J311, P/J308, 2K LCSS PWB
• 11D-110 2K LCSS Power Distribution RAP.
• Ensure that the SU1 safety gate switch is correctly actuated by the switch actuator,
PL 11.8 Item 3.
NOTE: The switch is closed and su24V to the staple head when the cam is
positioned either fully counterclockwise or fully clockwise. During off line stapling
when the safety gate is partly down, the cam is in the mid position, the switch is open
and +24V is not supplied to the staple head.
Install new components as necessary:
• Staple head unit, PL 11.20 Item 5.
• 2K LCSS PWB, PL 11.26 Item 1.
• SU1 safety gate switch, PL 11.8 Item 1.
