- Light Scanning Optics for Compact Jitter-Suppressed Imaging
Specific imaging-lens and coupling-lens conditions suppress surface eccentricity jitter while shortening the optical path and preserving image quality.
- Charging Roller Speed Switching to Prevent Drum Black Spots
Variable drum and charging roller speeds during non-image cycles dislodge foreign matter and prevent recurring black spot defects.
- Replacement Unit Usage Memory Reset for Firmware Compatibility
Backed-up usage data and default-value reset let replacement units stay usable across firmware versions without losing tracking information.
