Suggested Solutions
• Perform Initial Actions.
• Acquire your measuring tool from the Nationalization Kit and
check the frequency of the spot intervals:
• If the defect occurs every 44 mm on the prints, do not replace
the drum. This interval is caused by a damaged or defective
Developer Housing.
• If spots or bands occur every 147 mm on the prints, the Yellow,
Magenta, Black or Cyan Drum is damaged or light-shocked.
Run your Halftone Test Pattern to determine which color drum
is affected. Replace or swap the appropriate Drum cartridge.
• If the defect occurs every 374 mm on the prints, replace the
Fuser Belt Assembly.
• Perform Initial Actions.
• Check for Drum failure. Acquire your measuring tool from the
Nationalization Kit . Run the Halftone Test Pattern to determine
which color drum is affected. Replace or swap the affected
color Drum cartridge.
• Perform the Clean ROS Windows procedure.
If you run multiple width papers, refer to Fuser Hints and Tips and
Extended Fuser Life for more information.
• Perform Initial Actions.
• If problem continues, contact the Customer Support Center.
Unfused dry ink/toner collected on the ROS windows located above
the Drum Cartridge Drawer prevents the image for that color to
be captured. Streaks will display on the output if the ROS windows
are contanimated. Perform the ROS Window Cleaning procedure.
Use the provided wand to remove dry ink/toner that has collected
on the ROS window.
• Check the status of the CRUs/Supplies screen by pressing the
Home button on the Control Panel. Shake or replace the af-
fected dry ink/toner cartridge.
• Adjust the 2nd transfer settings using media profile in the Stock
Library.
• Determine if the drum is contaminated or light shocked by
running a set of Halftone Test Patterns to identify which color
is affected and then replace or swap the appropriate drum.
