8.15 Wrinkled and Torn Paper
The paper feeds and prints without jamming but wrinkles or skews (turns) in
the paper path. Inspect the following and fix, swap, or replace any damaged or
worn components:
1. Try some paper from a different source. Inspect the paper supply.
• Is the correct type of paper being used?
• Is the paper the correct size? The cassettes hold standard size paper
only. Nonstandard size sheets must be fed through the adjustable
paper tray.
• Is the paper wrinkled, damp, or is the stack compressed? Remove and
fan the stack. Paper should easily slide off the stack, not stick or bind
to the lower sheets.
• Is the paper tray guide adjusted correctly? Wrinkling and skew results
if the adjustable guide is too tight or too loose.
• Is the tray or cassette overloaded?
2. Clean and inspect the paper path guides. Look for broken or badly seated
components and clean up any contamination.
3. Clean the fixing unit rollers, using the procedure shown in Section 4.4.
Perform two or three cleaning passes if necessary. Replace the fixing unit
if the rollers do not clean.
4. Inspect or swap the following paper path rollers. Look for dirt, glazing,
nicks, or cuts. Replace any FRU that has deteriorated rollers.
• Tray pickup roller
• Cassette feed rollers
• Feed rollers
• Fixing rollers
• Faceup delivery rollers
