Solution
This print quality issue is most likely caused by a damaged Imaging Unit. Multiple components in the imaging unit can produce a frequency based repeating failure. For example, the photoconductor drum found in the imaging unit can be damaged due to improper handling when contacting a hard surface, Electrostatic discharge (ESD), or extended exposure to light.
Note: Do not touch the photoconductor drum or expose it to direct light for more than 10 minutes. Click here to see image.
