Note: Selecting Phase control ("1") could cause the fusing temperature control
board to emit low pitched noise.
Fusing T Adj.
Allows adjustment of the hot roller temperature at the center and ends of the roller
for the quality or thickness of the paper. The hot roller in this machine has two
1105
fusing lamps: one heats the center of the roller, and the other heats both ends.
Each fusing lamp can be adjusted separately.
Use SP1105-03, 04 to adjust for feeding standard paper from the by-pass tray,
and use SP1105-07, 08 to adjust for feeding thick paper from the by-pass tray.

[120°C ~ 220°C / 190°C / 1°C step]
Adjusts the temperature for re-heating the center of the
hot roller:
Reload Temp. = Fusing. Temp – SP Value
[0°C ~ 60°C / 30°C / 1°C step]
When the fusing temperature exceeds this setting, the
machine can operate.
Do not set a reload temperature (Spec. Temp – SP
Value) higher than the SP1105-02 setting.
Adjusts the temperature for re-heating the ends of the
hot roller:
Reload Temp. = Fusing. Temp – SP Value
[0°C ~ 60°C / 30°C / 1°C step]
When the fusing temperature exceeds this setting, the
machine can operate.
Do not set a reload temperature (Spec. Temp – SP
Value) higher than the SP1105-02 setting.
