11E-171 Copy Damage in the HVF BM RAP
Use this RAP to identify and correct the causes of copy damage in the HVF BM.
Procedure
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Check the following:
• Check the alignment between the IOT and the HVF BM, ADJ 11.1-171 .
• Look for paper fragments in the HVF BM paper path. Paper fragments can move through
the IOT and HVF BM paper path without causing a problem until they finally wedge them-
selves at some point. A likely place for a fragment of paper to be wedged is at the hole
punch assembly, where the top and bottom guides form the narrowest part of the paper
path.
• Ensure that the exit diverter gate solenoid, PL 11.150 Item 4 , operates correctly and has
it’s full movement.
• Ensure that the hole punches park at the fully open position. If they protrude, even
slightly, a jam will occur in the narrow paper path of the hole punch. Refer to the
11-044-
171 to 11-047-171 Punch Head Position RAP.
• Check that all the idler rolls in the HVF BM paper path are free to rotate, particularly those
on the jam clearance guides. Refer to
ADJ 4.1 Machine Lubrication.
• Make sure that the jam clearance guides 5a, 5b and 5c close and latch correctly.
• Check that the paper path ribs of the jam clearance guide 5b, PL 11.161 Item 7 and the
exit path PL 11.168 are free of scores and nicks. Check also for contamination and glue
from label stock.
• Make sure that the compiler carriage tampers move to the correct paper size.
• Check that the paper size reported on the user interface corresponds to the actual paper
size loaded in the trays, refer to the
07E Tray 1 and 2 Wrong Size Paper RAP.
• Make sure that the BM tampers move to the correct paper size, refer to the 11-066-171,
11-384-171 HVF BM Tamper Failure RAP.
• Ensure that the BM paper guide, PL 11.161 Item 7 , closes and latches correctly.
• If the top sheet of paper is being been torn from booklets, check that the components in
the lower crease roll gear and clutch assembly are correctly installed. Refer to the
replacement procedure in
REP 11.52-171 BM Crease Rolls, Gears and Bearings.
• If heavy-weight paper is used, the paper can stop in the vertical transport and cause a 10-
126 fault. The fault is caused when the vertical transport motor is over loaded. Check the
position of the jam clearance guides 5a, 5b and 5c. Check the vertical transport rolls and
bearings for contamination. If necessary remove and clean the drive shaft and the bear-
ings. If the problem continues then install a new transport motor,.
