Problem Sample Cause Solution
The printed page contains
wrinkles or creases.
NOTE: Orientation of the defect
depends on which way the page
travels through the paper path.
The paper is too light weight. If using paper lighter than 16lb/
80gm), try using heavier paper.
The roller or paper feed guide is
dirty.
Clean any dirty components.
A feed roller is deformed or has
deteriorated.
Replace any deformed or deteriorated
rollers.
The paper feed guide is
damaged.
Replace the paper-feed-guide unit.
Damaged fuser or registration
secondary transfer assembly.
Stop the product (by opening a
door) as the page is going
through the fuser. Check to see if
the crease occurs before
entering or after exiting the
fuser, and then do one of the
following:
●
If the creases occurs before
the page enters the fuser,
replace the registration
secondary transfer
assembly
●
If the creases occur as the
page is going through the
fuser, replace the fuser.
The front of the page is dirty.
The photosensitive drum is
dirty.
Replace the toner cartridges.
The fuser roller or pressure
roller is dirty.
Execute a Pressure roller clean mode
procedure. If the dirt does not come
off, replace the fuser.
NOTE: Cleaning the fuser with HP
tough paper provides better results
than with plain paper. The cleaning
process might need to be executed
several times to remove all
contaminants on the fuser.
Repetitive horizontal lines appear.
See repetitive image defect ruler.
Clean the indicated roller. If the
contaminant does not come off,
replace appropriate roller or
assembly.
