Vertical Repetitive Defects
If marks repeatedly appear on the printed side of the page:
•The toner cartridge is damaged. The circumference of the toner
cartridge drum is 3 3/4 inches (95 mm). If a repetitive mark occurs
every 3 3/4 inches (95 mm) on the page, replace the toner cartridge.
•The developer roller is defective. If a repetitive mark occurs every 2
inches (51 mm) on the page, replace the toner cartridge.
•The charger roller in the toner cartridge is defective. If a horizontal
black line occurs every 1 1/2 inches (38 mm), replace the toner
cartridge.
•The transfer roller has toner on it. If the defects occur every 2 1/16
inches (53 mm) on the back of the page, the problem will likely
correct itself after a few more pages.
Improperly Formed Characters
If characters are improperly formed, producing hollow characters, your
paper stock may be too slick. Try a different paper.
If characters are improperly formed, producing a wavy effect, the laser
scanner needs service. Call your authorized HP dealer or HP service
representative.
Vertical Line at Edge of Paper
If a vertical line appears on the page’s margin (usually the right
margin) after printing about 10,000 pages, the drum in your toner
cartridge is wearing out. The line will grow wider, with cross-hatching.
Replace the toner cartridge.
