Hole Punch Blanking Assembly Modification
The hole punch blanking assembly heats up as copies pass through. The increase in tempera-
ture causes the hole punch blanking assembly to bow. This bowing effect causes a reduction of
the paper path gap through the assembly, resulting in paper jams and misfeeds.
1. Remove the hole punch blanking assembly,
2. Figure 1. Dismantle the hole punch blanking assembly.
