Repetitive
vertical
defects
appear on the
printed page.
If the repetitive mark occurs at equal
distance between occurrences, either the
toner cartridge or a printer roller is
damaged.
Use the defect ruler to identify the
spacing. Check the appropriate
component and replace if necessary.
(see “Repetitive image defect ruler” on
page 87.)
The internal parts have toner on them. If the defects occur on the back of the
page, the problem will probably correct
itself after a few more printed pages.
Otherwise, clean the printer. See your
HP LaserJet 1000 Series user guide.
