Fusing Temperature Control: Temperature Feedback During Copying
This machine uses the feedback of the hot roller thermistor and two pressure roller thermistors, one at the
center and one at the end of the pressure roller, to control the fusing temperature. The SP codes settings
shown in the tables and illustrations below determine how fusing temperature is controlled for the paper
thickness modes (Mode 1 to 5) for each type of paper.
Here is a quick summary of the SP codes that are used to maintain optimum fusing temperature.
• These SP codes are set at the factory and normally should not require adjustment in the field.
1931 TTemp:HotRol
Sets the target temperature of the hot roller.
1932 TTemp:PreRol
Sets the target temperature of the pressure roller
1934 LTemp:HotRol
Sets the minimum difference in temperature allowed between the actual
temperature and the target temperature of the hot roller
1935 LTemp:PreRol
Changes the stepped adjustments of SP1932 (Target Temp: Pressure
Roller) by using the sum of the settings of SP1932 (Target Temp:
Pressure Roller) +SP1935 (Press FB Control Steps).
1941 PreFB:TDiff
Sets the temperature differential that determines when the machine
switches to the supplement mode for pressure roller feedback control.
(See description below.)
1942 PreFB:THI:NP
Sets the interval between temperature samplings for pressure roller
feedback control.
1943 PreFB:HT:SP
This SP sets the high temperature used by pressure roller feedback
temperature control for Custom paper.
1944 PreFB:LT:SP
Sets the low temperature used by pressure roller feedback temperature
control for Custom paper.
1948 PreRol TTemp
This SP determines when inching starts.
Here are more details about the settings of these SP codes.
