1937 Low Temp Environ Detect Control
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
C
(68
o
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 Temperature 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
o
C)
In a low temperature environment copying will not begin at the normal copy ready temperature.
[0 to 50/20/5]
2 Low Temperature Time Setting
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.
