IQ13 Unfused Copy/Toner Offset RAP
Initial Actions
• Replace the paper in use with fresh, dry paper of the correct specification.
• Check the post-Fuser transport areas for dirt.
• Ensure that the media being used matches the settings on the UI screen or print driver.
Using the next heavier setting may resolve the problem.
• If the Key Operator/Administrator has configured certain trays for a specific type of media,
ensure that the specified media is actually loaded in those trays.
Procedure
Check the following:
• Check the Sensor Assembly ( PL 7.2 ) for contamination or incorrect mounting. Clean,
repair, or replace as required.
• Check the Fuser ( PL 7.1 ) for damage, toner offsetting, paper wrap, or incorrect installa-
tion. Clean or replace as required.
After resolving the problem, make 10 blank copies (letter size, Black mode) to clean residual
toner from the Fuser Heat Roll and Fuser Belt. If the problem persists, or if Lead Edge contam-
ination is present, remove the Fuser Exit Chute (
PL 7.2 ) and clean any toner or paper residue
from the Exit Chute and the metal stripper baffle.
