Rap 4.1 Document Transport Jams - GBC FusionPunch II Service Manual

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
