Troubleshooting. Image Quality. IQ02 Charging Roll Pitch White Streaks-1
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
- On a halftone image, check that streaks appear in the FS direction at 38mm-pitch intervals.
- Make approx. 10 to 30 prints.
- Check that no streaks appear.
