IQ18 Print Damage RAP
Use this RAP when the prints have nicks, tears, creases, folds, curled edges or wrinkles.
Procedure
WARNING
Switch off the electricity to the machine. Disconnect the power cord from the customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.
WARNING
Do not touch the fuser while it is hot.
NOTE: If necessary, refer to GP 20 for the acronym list and cross reference lists of more com-
monly recognised part names.
1.
Make 10 copies. Inspect the copies for damage.
2.
If the copies have indentations that are repeated approximately every 57mm (2.25
inches), perform the following:
a.
Remove the ELA HOU - fuser assembly, PL 10.15 Item 1. Manually rotate the fuser
pressure roll. Carefully inspect the teflon coating for damage or evidence of imma-
nent failure.
NOTE: The teflon coating of the pressure roll can fail before the ELA HOU - fuser
assembly reaches 100K prints. The customer may also report orange or black frag-
ments of the teflon coating coming from the machine.
b.
If necessary, install a new ELA HOU - fuser assembly, PL 10.15 Item 1.
3.
Check the paper path for the following:
•
Obstructions.
•
Damaged guides and rolls. Pay particular attention to the areas that align with the
damage on the prints. For example, fuser stripper fingers.
•
Check the ribs on the ELA HOU - pickup assembly, PL 8.25 Item 1. Worn ribs can
cause damage to the prints. If necessary, install a new ELA HOU - pickup assembly,
PL 8.25 Item 1.
•
The edges of the paper path for protruding objects.
•
Ensure that paper path sensor actuators move freely.
4.
If the paper path is good, check that the paper and other media used is of the correct
weight and size. Refer to GP 22 Paper and Media Specifications.
5.
Install new components as necessary.
IQ19 DADF Lead Edge Offset RAP (M20F/2218)
Use this RAP when the printed image is offset 25-75mm (1-3 inches) from the lead edge of the
paper. Also use this RAP if the machine makes multiple blank copies after a single good copy.
Procedure
WARNING
Switch off the electricity to the machine. Disconnect the power cord from the customer
supply while performing tasks that do not need electricity. Electricity can cause death or
injury. Moving parts can cause injury.

monly recognised part names.
This error can be caused by the machine scanning the document too early or too late. Refer to
Wiring Diagram 5 (M20F) or Wiring Diagram 17 (2218). Perform the following:
