RAP 4.1 Document Transport Jams
Description
This RAP will help isolate document transport
jam problems in the FusionPunch II.
Initial Actions
Close all covers and doors and run the printer
to feed paper into the punch. When the paper
jams, open the punch top covers to determine
the location of the jam. Lift the Punch Tension
Strap Assembly (PL 4.3H) and ensure that the
Punch Assembly Side Guide (PL 4.3H) is
adjusted to the correct location, and that the
edge of the guide is situated under the Side
Guide Infeed Strip (PL 4.3H). To adjust the
Side Guide, refer to the User Manual and the
procedure entitled Setting the Side Guide in
Section 2.
If there is a jam indication, but the paper is NOT
jamming in the Punch, go to RAP 4.2 Punch
Jam Sensors RAP. If the paper is jamming at
the Punch Exit Sensor (or the Stacker Bypass
Exit Sensor, if installed) because of a problem
in the Stacker, go to RAP 5.3 Stacker Jams.
Procedure

Assembly.

output is on, go to Step 3.
Check the condition of the Document
Transport Main Drive Timing Belt.
The belt is loose or faulty.

When the motor activates, the infeed
belts in the Interface Assembly drive
smoothly.
Y N
Grasp the Document Transport
Main Drive Timing Belt and pull it
in a counterclockwise direction to
test its motion, and the motion of
the infeed belts in the subsystem
in which the jam is occurring. If
the belts in any area binding,
loose, or are not rotating
smoothly, check the belts,
pulleys, idlers and shafts to
ensure proper operation. Repair
as required (PL 4.1A - 4.1E).
Go to Step 1A.
Go to Step 1B.
1A. Check the Interface Assembly for
obstructions, burrs, bent or missing
components. Repair/replace as
required (PL 4.1A - 4.1E).

and recheck for jams. If the belt is faulty,
replace the Document Transport Main
Drive Belt (PL 1.1G).
2. On the Punch I/O PWB, disconnect P/J30.
Repeatedly activate and deactivate the
output.
LED L0A8 lights/extinguishes as the output
is activated\deactivated.
Y N
Reconnect J30. Check continuity and
for shorts to ground between P22-
OUTB1 on the Punch I/O PWB and
J1-HV08 on the Little Star Controller
PWB.
If the harness is faulty, replace it (PL
6.1A). If not, replace the Little Star
Controller PWB (PL 3.1).
