1937 LTemp:EnCtrl
These SP's are used to modify fusing temperature control sequence in a low temperature
environment where room temperature is below the optimum room temperature of 20
o
(68 F).
Note
• At optimum room temperature, the machine should reach the target fusing temperature
within 2 min.
• If the hot roller does not reach the target fusing temperature within 2 minutes, the machine
issues SC542 (Fusing Temperature Warmup Error).
1 Low Temp Setting
The machine monitors the time required for the hot roller temperature to reach the critical
temperature defined by this SP:
Copy Ready Temperature (SP1105) - This SP Value (Default: 20
In a low temperature environment copying will not begin at the normal copy ready temperature.
[0 to 50/20/5]
2 LTemp Time
This SP sets the length of time within which the hot roller temperature should reach the target
temperature set with SP1937-1. If the hot roller does not reach the SP1937-1 temperature
within this time limit, the machine will not allow copying to start when the temperature reaches
the ready temperature.
[0 to 120/120/1 sec.]
3 Inch Temp
If the inching target temperature (set with SP1948) is higher than 65
the hot roller temperature reaches this target hot roller temperature. If the pressure roller
temperature is less than 60
