2.10.7 OVERHEAT PROTECTION
If the hot roller temperature becomes higher than 231
°
C, the CPU cuts off the
power to the fusing lamp. At the same time, SC543 is generated.
Even if the thermistor overheat protection fails, there is a thermofuse in series with
the common ground line of the fusing lamp. If the temperature of the thermofuse
reaches 169
°
C, the thermofuse opens, removing power from the fusing lamp. At
the same time, SC 542 is generated and the machine stops operating.
2.10.8 PAPER EXIT
The paper overflow detection sensor [A] is located at the paper exit section of the
fusing unit. When this sensor is activated, the machine detects that the paper stack
height exceeded a certain limit and stops printing.
