Repeating defects
Example Cause Solution
If marks occur repeatedly only in one color and
multiple times down a page, a toner cartridge
or photoconductor may be defective.
Replace the toner cartridge if the defects occur
every:
• 33.5 mm (1.32 in.)
• 35.7 mm (1.41 in.)
Replace the photoconductor if the defects
occur every:
• 28.3 mm (1.11 in.)
• 72.4 mm (2.85 in.)
If marks occur down the page repeatedly in all
colors, the fuser may be defective.
Replace the fuser if the defects occur every
116.2 mm (4.58 in.).
