Theory of Operation
2-24
Fuser Warm-Up
The halogen lamp is turned on when the fuser warm-up begins. When the
surface temperature of the heat roller (detected by the thermistor) reaches the
fuser control temperature (standby temperature), the fuser warm-up is ended.
Fuser Temperature Cycling
The fuser temperature does not remain at a single, constant value, but varies
within a temperature range. There are several ranges, which are summarized
in the table. Except for Standby, the setting is determined by the media type
selection.
