Fuser Controls
The printer switches the Heater Rod ON or OFF according to the Rated
Fuser Temperature parameters set in Configuration Code 9.
There are two Rated Fuser Temperature settings:
• Standby Mode Temperature – When thefuser is warming up or the Main
Motor is idle.
• Running Mode Temperature – During a print cycle or in the Recovery Routine. Runing Mode
temperature is slightly higher than Standby Mode Temperature.
Heater Rod Control
The printer switches the Heater Rod ON when the surface temprature of the
Heat Roll reaches the Low Temperature range.
The printer switches the Heater Rod OFF when the surface temperature of the
Heat Roll reaches the High Allowable Temperature range.
Fuser Warm-Up
Fuser warm-up begins whe the printer switches ON the Heater Rod. Fuser
warm-up ends when the Temperature Sensor thermistor senses the Heat Roll
surfaces has reached Standby Mode Temperature.
The Main Motor runs continuously during Fuser Warm-up.
Fuser Temperature Table
The table below shows the Heat Roll temperature parameters. The Rated Fuser
Temperature value is variable. You can change it using Configuration Code 9.
