Control Logic does not detect the signal Staple Head Home (L) within 450msec since the start
of Staple Head Close operation.
Initial Actions
Refer to BSD 12.13 for the following procedure:
•
Ensure that connector
P/J1092
is seated correctly to the Stapler Assembly, that connec-

P/J1044
is seated correctly to the Finisher PWB and that there are no obvious
crimped or broken wires on either connector.
•
Check for staple jams.
Procedure
Remove the Stapler Cover Assembly
(REP
Staple Assembly toward the rear of the Finisher until the semicircular cam on the front of the
assembly is facing forward. Manually rotate the cam in a clockwise direction until the flat por-
tion of the cam is facing up. Enter dC330 012-273 Staple Ready Sensor. The display indi-

•
Stacker Full (H) is detected during the Stacker Tray height adjustment (descending).
•
Stacker Full (Mixed Size) (H) is detected during the Stacker Tray height adjustment
(descending) while ejecting mixed-size sets.
•
A mixed-size set is ejected after Stacker Full (Mixed Size) (H) is detected.
Initial Actions
Refer to BSD 12.15 for the following procedure.
Ensure that the Stacker Tray is empty. If the fault is declared with an empty Stacker Tray, pro-
ceed with this RAP.
