Room Temperature
From when the main machine is switched on until fusing
temperature reaches 175°C, the time required to reach the copy
ready temperature is determined by SP1937-2 (Default: 2 min.)
This is the "prescribed time" to reach the target hot roller
temperature..
! If hot roller reaches the target temperature within the time
prescribed by SP1937-2., copy ready temperature is at
! If hot roller does not reach the target temperature within the
time prescribed by SP1937-2, copy ready temperature is
not set at . Rather, after the temperature reaches
inching starts with rotation of the pressure roller. When the
pressure roller reaches 60°C at
temperature.
If warm-up reaches the target fusing temperature within the
prescribed time (SP1937-2), this is the copy ready temperature.
Temperature of the hot roller is monitored and controlled within
±5°C of target hot roller temperature.
Temperature of the pressure roller is monitored and controlled
within ±5°C target pressure roller temperature.
