Fusing Temperatures
When the main switch turns on, the CPU turns on the fusing lamp. The lamp stays
on until the thermistor detects the standby temperature. Then the CPU raises the
temperature to the printing temperature.
The fusing temperature for each mode is as follows.

The heating and pressure roller temperatures for fusing are stored in SP1-105-004
to 028 and SP1-105-051 to 054.
When the machine is switched on, the fusing lamp temperatures increase to those
specified by SP1-104-025.
The print ready temperature is slightly less than the fusing temperature. The
difference is specified by SP1-105-001 and 002.
