A. Warm-up
• Four different types of warm-up control are employed for varying the set temperature of
each roller, thereby preventing fusing performance from being degraded due to environ-
mental changes.
• Priority is given to the high humidity control.
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)

pleted (machine interior humid-
ity is 70 % or more)

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
112
and resumes the print cycle
for the rest of printed pages
to be produced after the
Fusing Pressure Roller tem-
perature reaches 130 °C.

Priority is given to this mode
155 if the humidity is 70% or
more.
Temperature control during
Power Save is 165 °C for the
Heating Roller and 155 °C
