Temperature Control

The fusing unit has these components for temperature control:

• The fusing thermistors [A] [B] send a signal when the fusing temperature goes past the threshold.
• The central thermistor [B] is the one that is used for fusing temperature control.
• The fusing thermostat [C] breaks the electric circuit when the fusing temperature goes past the threshold. The thermostat is on the same electrical circuit as the fusing lamp, so the fusing lamp goes off if the fusing thermostat breaks the electrical circuit.

• [A]: Idling ready temperature (80°C)
  The fusing unit starts to rotate (idling) until 3 seconds after stand by (a).
• [B]: Ready temperature (155°C)
  This is the temperature finish warm-up condition.
• [C]: Standby temperature (173°C)
  This is the temperature to wait for a print job.
• [D]: target temperature of 1st print (This depends on the target temperature of each paper type; see the table below)
  The machine keeps this temperature during printing.
• [E]: 10 seconds recovery temperature (150°C)
  This is the low power mode for printing. This temperature is lower than the stand by temperature [C] and saves power.
• [F]: Sleep mode
  The machine turns off power to the engine unit for sleep mode after the machine has not got a print job for 10 minutes (at the default setting).
