Temperature/Humidity Sensing System
The printer has a temperature/humidity sensor board installed under the
far end of the toner release assembly.
The DC controller monitors this sensor and adjusts the following high-
voltage values if a change in temperature or humidity is sensed.
• Primary charging
• Transfer bias
• Attraction bias
• Discharge AC bias
• Separation discharge
In addition to the intervals specified on the previous page, tempera-
ture/humidity sensing is performed every 30 minutes while the power is
turned on.
Note The separation discharge value can be forced on or off manually
by means of the density control panel .
