Composition/Operation
Temperature control during color printing (plain paper)
[1] During warm-up cycle
Heat the heating roller temperature to
178
°
C in average 45 seconds.
(100 V – 120 V area)
Heat the heating roller temperature to
178
°
C in average 49 seconds.
(220 V – 240 V area)
[3] During a print cycle
Heating roller temperature setting: 189
°
C
(if the heater roller temperature at the start of
the warm-up cycle is 60
°
C or less)
Heating roller temperature setting: 184
°
C
(if the heater roller temperature at the start of
the warm-up cycle is more than 60
°
C)
*b: Temperature control is performed accord-
ing to the temperature measured with the
temperature/humidity sensor. For details, see
“(2) color printing (1-sided).”
P.65
[2] In standby state
Heating roller temperature setting: 180
°
C
*a: If the heating roller temperature is 60
°
C or
less when the warm-up cycle is started, tem-
perature control is performed with the heating
roller temperature setting changed to 185
°
C.
(5 min.)
After the lapse of the 5 min. period, the tem-
perature stabilizes at 180
°
C.
