If BCR is deformed at the BCR-to-Photoreceptor NIP area, the trace may appear as thin white streaks in the FS direction on the highlight area at intervals of Charging Roll Pitch.

This problem may occur with a New Drum Cartridge that has been stored for a long period, or in a machine that has had a long rest in a high-temperature environment. (Halftone Image)

Procedure

1. On a halftone image, check that streaks appear in the FS direction at 38mm-pitch intervals.
2. Make approx. 10 to 30 prints.
3. Check that no streaks appear.
