Check the harness between P10 on the
Stacker AC/DC Distribution PWB and the
Stacker Bypass Motor. If the harness is
OK, replace the Stacker Bypass Motor (PL
1.3A).
20. On the Stacker AC/DC Distribution PWB in
the problem Stacker, check for 110 VAC
across P/J 1-NEU and P/J 1-LINE. There
is 110 VAC at this point.
Y N
Go to RAP 1.2 AC Power to the
Stacker.
Replace the Stacker AC/DC Distribution
PWB (PL 3.3).
21. On the Stacker I/O PWB in the problem
Stacker, disconnect P/J 1 to the Bypass
Exit Sensor. Observe the Control Panel
display.
With P/J 1 disconnected, the Jam Bypass
(2) Sensor dialog is still present on the
Control Panel display.
Y N
Ensure that there is no paper blocking
the Bypass Exit Sensor. If the sensor
is unobstructed, replace it (PL 1.3 A).
Go to Step 22.
22. Depending upon where the jam is
occurring, refer to the table for Stacker 1 or
Stacker 2 below. Enter the Diagnostic
Mode (GP1) and select the Bypass Exit
Sensor input.

Sequentially block and unblock the sensor
and observe the Control Panel for a change
in state (0 to 1, or 1 to 0).
There is a change in state when the sensor
is blocked and unblocked.

Go to Step 23.
Go to Step 24.
23. Using the following table, on the Stacker
I/O PWB check the LED that corresponds
with the sensor. Sequentially block and
unblock the sensor and observe the LED
for a change in state (Blocked = Off,
Unblocked = On).

Replace the cable between the
Stacker I/O PWB P/J 25 and the
Punch Daughter PWB P/J 25 (PL
6.2A).
Replace the Punch Daughter PWB (PL
3.1). If the problem is still present, replace
the Little Star Controller (PL 3.1).
25. On the Stacker I/O PWB disconnect P/J 1.
Check LED LIB8 to see if it is lit when the
connector is disconnected.
NOTE: In this step, you are checking
to see if the LED remains LIT when the
P/J is disconnected, NOT flashing.
LED LIB8 remains lit when P/J1 is
disconnected.
Y N
Leave the connector disconnected
and go to Step 26.
Leave the connector disconnected and go
to Step 27.
26. Check the continuity of the cable between
the Stacker I/O P25-INB8 and the Punch
LIB8
Daughter PWB P/J25-8
The continuity is OK.

Replace the cable between the
Stacker I/O PWB P/J 25 and the
Punch Daughter PWB P/J 25 (PL

the Little Star Controller (PL 3.1).
27. On the Stacker I/O PWB, place a jumper
between the P/J 1-INB8 and P/J1-0V. With
the jumper in place, LED LIB8 should
extinguish.
