Warm-up completed state
First-in-the-morning warm-up
completed (Fusing Pressure
Roller temperature is 60 °C or
less)
Ordinary warm-up completed
(Fusing Pressure Roller tem-
perature exceeds 60 °C)
High humidity warm-up com-

ity is 70 % or more)
Recovery from Power Save
B. During a copy cycle
• To achieve the intended level of fusing performance, the set temperature of each roller is
varied according to the paper type.
Paper Type
Plain paper (165 mm/s)
Plain paper (100 mm/s)
Plain paper (60 mm/s)
Thick paper 1
Thick paper 2
Thick paper 3

OHP (humidity during a color print cycle exceeds 60%)
C. In standby
• The fusing temperature in the standby state is prevented from being dropped.
Standby State
Ordinary standby
When the Power Switch is turned ON
Machine interior humidity 70% or higher
(high humidity)

Remarks
If a multi-print cycle is run
immediately after the warm-
up cycle has been com-
pleted, the machine pro-
duces one printed page only
97
and resumes the print cycle
for the rest of printed pages
to be produced after the
Fusing Pressure Roller tem-
perature reaches 130 °C.
130
Priority is given to this mode
150 if the humidity is 70% or
more.
Temperature control during
Power Save is 160 °C for the
Heating Roller and 150 °C
150
for the Fusing Pressure
Roller.
