Marks occur repeatedly only in one
color and multiple times on a page:
• Replace the toner cartridge if the defects
occur every:
– 45.1 mm (1.78 in.)
– 60 mm (2.4 in.)
• Replace the photodeveloper (black
alone or all other colors at once) if the
defects occur every:
– 31.5 mm (1.2 in.)
– 94 mm (3.7 in.)
Marks occur across the page repeatedly
in all colors:
• Replace the transfer belt if the defects
occur every 27 mm (1.1 in.)
• Replace the fuser if the defects occur
every 140 mm (5.5 in.)
