Possible cause Solution
1 The print cartridge or fuser is damaged. The
circumference of the photoconductive drum inside of
the print cartridge is 94.2 mm (3.7 inches). If the
defect repeats at this interval, the defect is
associated with the drum.
Repetitive defects caused by the fuser roller repeat at
94.0 mm (about 3.7 inches) Because the fuser roller
is just 2 mm (0.07 inch) smaller than the
photoconductive drum it can be difficult to distinguish
defects that the photoconductive drum causes from
those that the fuser roller causes.
1 Inspect the drum for scratches or other damage.
Replace the print cartridge for defects that repeat
at 37.7 mm (1.5 inches), 62.8 mm (2.5 inches),
54.0 mm (2.1 inches), or 94.2 mm (3.7 inches).
2 Process a cleaning page. See Cleaning the fuser.
3 If the problem persists, and the defect repeats at
the 75.0 mm (2.95 inches) or 94.0 mm (about
3.7 inches), replace the fuser (see
Fuser).
For more information about repetitive defects, see
Repetitive defect ruler.
2 The rollers are dirty. A dirty roller in the paper path
can cause a repetitive defect.
Examine and clean (or replace) the rollers in the
paper path.
3 The media does not meet specifications. Try a different media type or quality.
4 Preprinted form paper is used. Some preprinted forms (for example, letterheads) use
an ink that cannot withstand the high temperatures in
the fuser. Check the media for type and quality.
Replace the media, and advise the customer to use
the HP-recommended media and to store it correctly.
See
Media specifications.
