Mode Number/Name Function/[Setting]
By-pass Paper Size Display 007
Displays the by-pass paper width sensor output.

to exit the display.
Fusing Idling 103*
Selects whether or not fusing idling is performed.
[0 = No / 1 = Yes]
Normally disabled in this machine. However, enable this
mode if fusing is incomplete on the 1st and 2nd copies,
which may occur if the room is cold.

6.13.5 Fusing Temperature Control
Fusing Temperature Adjustment
1 Stand-by Adjusts the fusing temperature for standby mode.
[160 ~ 190 / 175 / 1°C/step]
105*
2 Low power level 2 Adjusts the fusing temperature for low power level 2.
[0 ~ 100 / 60 / 1°C/step]
Lower values cause the machine to take a longer time to
reach the ready condition.
Fusing Temperature Display 106
Displays the fusing temperature.
Press

to exit the display.
Fusing Soft Start Adjustment
1 Stand-by Adjusts the number of zero-cross cycles of the fusing
lamp AC supply needed to bring the fusing lamp power to
100% while bringing the lamp up to the standby
temperature. Increase this value if the machine is
experiencing sudden power dropouts.
[North Am.: 0 = 3 cycles / 1 = 10 cycles / 2 = 20 cycles]
[EU/Asia: 0 = 3 cycles / 1 = 10 cycles / 2 = 20 cycles]
☛
6.13.5 Fusing Temperature Control
107*
2 Copying Adjusts the number of zero-cross cycles for the fusing
lamp AC supply needed to gradually raise the fusing lamp
power to 100% during printing. Increase this value if the
machine is experiencing sudden power dropouts.
[North Am.: 0 = 3 cycles / 1 = 10 cycles / 2 = 20 cycles]
[EU/Asia: 0 = 3 cycles / 1 = 10 cycles / 2 = 20 cycles]
☛
6.13.5 Fusing Temperature Control
Fusing Soft Start Setting 108*
Selects whether the fusing temperature control cycle is
1 second or 3 seconds.
[0 = 1 / 1= 3 s]
Setting this item to “1” (3 s) reduces the power supply
fluctuation that occurs when the fusing lamp switches on.
☛
6.13.5 Fusing Temperature Control
Fusing Nip Band Check 109
Checks the fusing nip band.
[1 = Start / 0= Stop]
IAJ
AC Frequency Display 902
Displays the fusing lamp power control frequency (as
detected by the zero cross signal generator).
The displayed value is 1/5 the actual frequency: 10 = 50
Hz, 12 = 60 Hz.
