Reducing the Copying Speed
0006-2922
The machine is not equipped with a paper width detection mechanism; for this reason, if paper with a limited width
is used in continuous printing, the ends of the fixing heater would overheat. To prevent overheating, the machine
switches among 3 copying speeds with reference to the readings of the sub thermistor.
1. Normally, the machine reduces the speed to 4 ppm when the reading of the sub thermistor reaches 245 deg C/473
deg F or higher.
2. The machine will further reduce the copying speed to 3 ppm if the reading of the sub thermistor reaches 255 deg
C/491 deg F or higher after it has reduced it to 4 ppm.
3. The machine will further reduce the copying speed to 2 ppm if the reading of the sub thermistor reaches 260 deg
C/500 deg F or higher after it has reduced it to 3 ppm.
