Fusing Temperatures - Ricoh G133 Service Manual

Fusing Temperatures

[A]: Heating roller temperature
[B]: Pressure roller temperature
[C]: Heating roller target temperature for the ready condition
[D]: Extra idling target temperature
[E]: Idling target temperature
[F]: Heating roller target temperature for the print condition
[G]: CPM down threshold temperature
[H]: Pressure roller target temperature
Warm-up mode [1]:
The machine uses the following formulas to decide the actual heating roller target
temperature for the warm-up mode.
If the ambient temperature ≤ 17°C (adjustable with SP1-112-001)
T1 = T2 + T3
T1: Actual target temperature
T2: Heating roller target temperature for the ready condition (adjustable with
SP1-105-001, default: 138°C)
T3: Environment correction (adjustable with SP1-112-003, default: 5°C)
If the ambient temperature ≥ 30°C (adjustable with SP1-112-002)
T1 = T2 - T4
T1: Actual target temperature
T2: Heating roller target temperature for the ready condition (adjustable with
SP1-105-001, default: 138°C)
T4: Environment correction (adjustable with SP1-112-004, default: 0°C)
If 17°C (adjustable with SP1-112-001) < Ambient temperature < 30°C (adjustable with
SP1-112-002)
