ADJ 10.1 Fuser Temperature (NVM)
Purpose
The purpose is to adjust the temperature of the Fuser Heat Roll in order to obtain the correct
fusing temperature for the media type that is being used. The actual surface temperature of the
Heat Roll will be 20 degrees hotter than the set point values.
Introduction
The fusing temperature is limited to a range of 300 to 400 degrees Fahrenheit (149 to 204
degrees Celsius). The SETPOINT value displayed in [1060], [1062], and [1063] is the last two
digits of the Fahrenheit temperature. For example: 1060 FUSER TEMPERATURE SETPOINT:
50 is 350 degrees Fahrenheit which correlates to a heat roll surface temperature of 370
degrees F (187.7 C). The fusing temperature can be adjusted in 1 degree increments from 300
to 400.
Adjustment
1. Ensure that the Fuser Thermistors are in contact with the Fuser Heat Roll.
2. Enter diagnostics.
3. (Figure 2): Enter code [1060] in order to adjust the Fuser Temperature for bond paper to
350. The following message is displayed.
Figure 1 Fuser Set point Screen
a. Use the Previous button to decrease the Set Point, lowering the fusing temperature.
b. Use the Next button to increase the Set Point, raising the fusing temperature.
c. Press the Enter button in order to store the value in NVM.
d. Press the Exit button two times.
4. (Figure 3): Enter code [1062] in order to adjust the Fuser Temperature for vellum to 350.
The following message is displayed.
