TONER MASS AMOUNT CONTROL
6.3 TONER MASS AMOUNT CONTROL
6.3.1 OVERVIEW
This machine automatically controls the toner mass quantity on the transfer belt.
The control procedure has four phases:
1. ID sensor calibration
2. Test pattern processing
3. Reference equation processing
4. Development bias adjustment
NOTE: The machine does not check the toner density on the paper.
6.3.2 ID SENSOR CALIBRATION
[A]
1. The cyan development unit makes a
rectangular image (patch) [B].
2. This cyan image on the transfer belt [A]
reflects the light from the ID sensor [C].
3. The controller examines the signal level
from this sensor, and calibrates the ID
sensor.
