6. Detailed Function Descriptions
• This idling keeps the heating roller warmed up equally while it is heated. This temperature is
controlled with SP 1912 5, and the durations of fusing idling are controlled with SP 1912 6,
and 8 to 14
• You can also adjust this with SP 1912 2 and SP 1105 43
2. At the end of a job: [F]
• This prevents the heating roller's overheating. After printing, the machine turns the heating roller
with no heating. You can adjust the setting with SP 1912 7
3. At intervals of 4 hours if the machine is not used for a long time
• This prevents the deformation of the hot roller and pressure roller.
• Controlled by SP 1912 3 (interval) and 4 (duration)
• Enable/disable this idling feature: SP 1912 1
For fusing idling at the start of a job, the duration and the fusing unit temperature during idling are also
corrected for ambient temperature. SP 1917 controls all the corrections. The temperature/humidity sensor
measures the room temperature. Corrections are made at the following times:
• Room temperature is below 18ºC (L threshold, controlled by SP 1917 8)
6
• Room temperature is above 30ºC (H threshold, controlled by SP 1917 7)
Idling Ready Temperature before First Print Job: [A]
This is the idling ready temperature for the heating roller before the first print job. You can adjust the setting
with SP 1912 5. The default is 100°C. If the heating roller temperature does not reach this temperature
within 15 seconds after the heating lamp turns on, SC 542 occurs.
Machine Ready Temperature: [B]
You can adjust the setting with SP 1913 2. The default is 150°C.
Print ready temperature: [C]
You can adjust the setting with SP 1105 22. The default is 160°C.
Target Printing Temperature: [D]
This is adjusted by the value stored in SP 1104 23. This value is added to the print ready temperature. The
default is "10°C".
