be replaced.

Repeating defects
Either the print cartridges are 
defective, the image transfer unit 
and transfer roller are defective, or 
the fuser is defective.
Marks occur repeatedly only in one color and 
multiple times on a page:
• Replace the cartridge if the defects occur every:
– 48 mm (1.9 in.)
– 97 mm  (3.8 in.)
Marks occur down the page repeatedly in all 
colors:
• Replace the transfer roll if the defects occur every 
60 mm (2.4 in.)
• Check the first transfer bellcranks and springs or 
replace the image transfer unit if the defects occur 
every 101 mm (4 in.)
• Replace the fuser if the defects occur every 
148 mm (5.8 in.)
Marks occur on every third or sixth page in any 
color:
Replace the image transfer unit.
Color 
misregistration
Color has shifted outside of the 
appropriate area or has been 
superimposed over another color 
area.
Re-seat the cartridges by removing them from the 
printer and then reinserting them.
If you still have the problem, refer to the Color 
Alignment section under the Utilities Menu.
