Repeating defects
1. Print a few more pages to see if the problem corrects itself.
2. The print cartridge or fuser is damaged. The circumference of the photoconductive drum inside of
the print cartridge is 96 mm (about 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.
Inspect the drum for scratches or other damage. Replace the print cartridge for defects that repeat
at 44 mm (1.7 inches) or 58 mm (2.3 inches).
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.
3. Clean the inside of the device and then run a cleaning page. See
Clean the device on page 98.
4. 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.
5. 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.

This type of defect might occur when using preprinted forms or a large quantity of narrow media.
1. Print a few more pages to see if the problem corrects itself.
2. Make sure that type and quality of the media you are using meet HP specifications.
3. If the distance between defects is 47 mm (1.9 in), 62 mm (2.4 in), or 96 mm (3.8 in), the print
cartridge might need to be replaced.
