IQ-15 Photoreceptor Pitch Color Stripes
Vibrations during the Imaging Unit CRU transportation may cause scrapes and
friction in the BCR and the Photoreceptor, resulting in leftover electrostatic
memory on the Photoreceptor that generates thin white streaks in the FS direction
on the highlight portion at the Photoreceptor Pitch.
Cause
This problem may occur right after the replacement of Imaging CRU (occurs at
Halftone image quality).
Initial Actions
• Check the paper transfer path.
• Ensure there are no debris on the transfer path.
