Specifies the paper size for tray 2. This specifies which size is detected for a sensor
output of 1011 (see section 6 for details).
[Machine Temp.] Machine Temperature Correction
Th: Threshold, Heating or Pressure roller
1912
Corrects the fusing temperature depending on the temperature inside the machine.
If the temperature inside the machine is too high or low, this may cause hot or cold
offset image at the fusing section. To avoid the offset image, the fusing temperature
is corrected depending on the temperature inside machine, which is monitored by
the thermistor located on the right side of the laser optics housing unit. If the
temperature inside the machine is detected as high or low (based on the settings of
SP1-912-001 or 002), the fusing temperature is decreased or increased by the
temperature specified in SP1-912-003 to 006.
Th:High Temp *BCU
[0 to 50 / 30
/ 1°C/step]
1912 001
Sets the threshold for entering the high temperature condition.
Th:Low Temp *BCU
[0 to 50 / 17
/ 1°C/step]
1912 002
Sets the threshold for entering the low temperature condition.
H: High Temp *BCU
[0 to 15 / 0
/ 1°C/step]
1912 003
Sets the fusing temperature decrease for the high temperature condition.
1912 004 P: High Temp *BCU
[0 to 15 / 0
/ 1°C/step]
H: Low Temp *BCU
[0 to 15 / 5
/ 1°C/step]
1912 005
Sets the fusing temperature increase for the low temperature condition.
1912 006 P: Low Temp *BCU
[0 to 15 / 5
/ 1°C/step]
H: Temp Control *BCU
[10 to 50 / 34
/ 1°C/step]
1912 007
Decreases the fusing temperature by 10 °C if the temperature inside machine,
which is monitored by the thermistor located on the left side of the laser optics
housing unit, reaches the set temperature in this SP.
