Function/[Setting]
Displays the by-pass paper width sensor output.
Press ! to exit the display.
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
Adjusts the fusing temperature for standby mode.
[160 ~ 190 / 175 / 1°C/step]
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.
Displays the fusing temperature.
Press ! to exit the display.
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
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
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
Checks the fusing nip band.
[1 = Start / 0= Stop]
IAJ
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.
