Problem
Repeating Defects at Regular Intervals on Prints
The prints show any defect type that repeats at intervals that can be measured.
Suggested Solutions
Measure the frequency of the spot intervals.
Note
A measuring tool is provided in the nationalization kit that came with your press.
• 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. Contact the Customer Support Center.
• If spots or bands occur every 147 mm on the prints, a drum cartridge is damaged or light
shocked.Replace or swap the appropriate drum cartridge; refer to Replacing a Drum Cartridge.
• If the defect occurs every 374 mm on the prints, replace the fuser belt assembly. Refer to
Fuser Assembly Procedures.
Problem
Streaks or Lines on Prints
The prints show solid color streaks or lines running from lead-edge to trail-edge (LE/TE) on the
prints.
Note
For image quality defects that run in the inboard-to-outboard (IB/OB) direction, refer to Banding
on Prints.
Suggested Solutions
• Perform Cleaning the Raster Output Scanner (ROS) Window Areas.
• If streaks or lines continue after cleaning the ROS windows, check for drum failure:
- Acquire or print the measuring tool.
A measuring tool is provided in the nationalization kit that came with your press.
- To determine which drum cartridge is affected, run the Halftone Test Pattern.
- Replace or swap the appropriate drum cartridge; refer to Replacing a Drum Cartridge.

stock.
