Name of part Voltage (Current) during Print Cycle
Image Corona Wire About -5.8KV (-2.0mA +/-0.05mA)
Grid Plate -XV +/-20V
(It varies following the machine temperature.)
Developer Roller -YV +/-3V
(It varies following the detection by Density Sensor.)
Regulation Roller -100V +/-3V from the voltage of Developer Roller
(Center)
Regulation Roller +365V +/-3V from the voltage of Developer Roller
(Both sides)
Toner Supply Roller -350V +/-3V from the voltage of Developer Roller
Transfer Corona +520V +/-30V
(When the Insulated Drum is used.)
Separation Corona AC (11KVp-p) + DC (-250V +/-3V : Plain paper)
Cleaning Roller +800V +/-3V
Reference
When printing is going to finish or when the used Roll Deck is changed with other one, "Toner
Collection Process" is performed to take back the remained toner into the Developer Unit.
Refer to [3.4 Toner Collection Process] on the page 3-18 for the detail.
