Ricoh A156 - Factors Affecting Process Control

1.1.2 Factors Affecting Process Control
In this copier, the following items are controlled during the copy process to
maintain good copy quality:
•
Exposure lamp voltage
•
Drum charge roller voltage
•
Development bias voltage
•
Toner supply
The machine controls the items listed above by monitoring the following
electrical components:
•
Operation panel (manual ID selection and reproduction ratio)
•
ADS sensor
•
TD sensor
•
ID sensor
•
Drum charge thermistor
•
Paper size detectors
•
RAM board (drum rotation time, SP mode data, and paper size data)
