4. Measure the AC voltage at the problem
Stacker Power Switch/Circuit Breaker,
across the brown and blue wires.
The voltage is within 108 VAC to 120 VAC
tolerance.
Y N
Unplug the Stacker from the wall
outlet. Disconnect the Line Filter from
the Stacker Main Power Switch/
Circuit Breaker. Reconnect the
Stacker to the wall outlet. Check for
108 VAC to 120 VAC between the
Line Filter and the Main Power
Switch/Circuit Breaker.
There is 108 VAC to 120 VAC
between these two points.
Y N
Verify the wall outlet voltage.
Check continuity on the Power
Cord, replace if necessary. If the
problem still exists, replace the
problem Stacker Main Power
Switch/Circuit Breaker (PL 1.2A).
Replace the Line Filter (PL 1.2A).
Replace the harness between the Stacker
1 Main Power Switch/Circuit Breaker and
the Stacker 1 AC/DC Distribution PWB (PL
6.2C).
5. This is a dual Stacker configuration.
Y N
Go to Step 6.
The failure is occurring in Stacker 1.
Y N
On the Stacker 2 AC/DC Distribution
PWB, check +24 VDC to Stacker 2 by
placing the meter leads across P/J
13-24V and P/J13-0V.
There is +24 VDC at this point.

Y N
On the Stacker 1 AC/DC
Distribution PWB, check +24
VDC across P/J 13-24V and P/
J13-0V. If there is +24 VDC at
this point, replace the harness
between P/J 13 on Stacker 1 and
Stacker 2 (PL 6.2B). If +24 VDC
is not present, go to Step 6.
Replace the Stacker 2 AC/DC
Distribution PWB (PL 3.2).
Go to Step 6.
6. On the Stacker 1 AC/DC Distribution PWB,
check +24 VDC to Stacker 1 by placing the
meter leads across P/J 14-24V and P/J14-
0V.
There is +24 VDC at this point.
Y N
Go to RAP 1.5 Stacker +24 VDC
Power.
Replace the Stacker 1 AC/DC Distribution
PWB (PL 3.2).
7. On the problem Stacker AC/DC Distribution
PWB, disconnect P/J 7 to the Stacker Tray
Motor. Activate the Stacker Tray Motor
using the information in the table below.

With the output active, Check for 108 VAC
to 120 VAC between J7-NUI and J7-FWD,
and then J7-NUI and J7-REV.
NOTE: Check voltages across both
J7-FWD and J7-REV with the Stacker
Direction output in both positions.
With the outputs active, there is 108 VAC to
120 VAC between J7-NUI and J7-FWD,
and between J7-NUI and J7-REV.
Y N
Replace the Stacker AC/DC
Distribution PWB (PL 3.2) in the
problem Stacker.
Check continuity between P7 and the
Stacker Tray Motor. If the harness is OK,
replace the Stacker Tray Motor (PL 1.2B).
8. On the problem Stacker AC/DC Distribution
PWB, disconnect P/J 8 to the Stacker O-
Ring Motor. Activate the Stacker O-Ring
Motor using the information in the table
below.

With the output active, check for 108 VAC
to 120 VAC between J8-NUI and J8-RMT2.
There is 108 VAC to 120 VAC between
these points.
Y N
Replace the Stacker AC/DC
Distribution PWB (PL 3.2) in the
problem Stacker.
