The machine turns off the IH coil unit (heating roller) and then turns on the pressure roller
lamp. The temperature of the pressure roller is kept at 150°C (adjustable with
SP1-105-012).
The machine also executes the idling rotation in the stand-by mode for 0.7 seconds
(adjustable with SP1-115-002) every 60 minutes (adjustable with SP SP1-115-001).
Print ready mode [5]:
The machine turns off the pressure roller lamp and turns on the IH coil unit (heating roller)
when the machine recovers.
The target temperature after recovery is 170°C (adjustable with SP1-105-083). But if the
machine does not get any printing job for 10 seconds (adjustable with SP1-113-002), the
machine turns off the IH coil unit (heating roller), turns on the pressure roller lamp, and then
returns to the stand-by mode.
If the machine gets a printing job, the machine uses the following formulas to decide the
actual heating roller target temperature for feeding paper and processing the image (this is
the print ready mode).
If the ambient temperature ≤ 17°C (adjustable with SP1-112-001)
Ta = Tb + Tc
Ta: Actual target temperature for printing
Tb: Heating roller target temperature for each paper type (adjustable with
SP1-105-030 to -080)
Tc: Environment correction (adjustable with SP1-112-003, default: 5°C)
If the ambient temperature ≥ 30°C (adjustable with SP1-112-002)
Ta = Tb - Tc
Ta: Actual target temperature for printing
Tb: Heating roller target temperature for each paper type (adjustable with
SP1-105-030 to -080)
Tc: Environment correction (adjustable with SP1-112-004, default: 0°C)
If 17°C (adjustable with SP1-112-001) ≤ Ambient temperature ≤ 30°C (adjustable
with SP1-112-002)
Ta = Tb
Ta: Actual target temperature
Tb: Heating roller target temperature for each paper type (adjustable with
SP1-105-030 to -080)
The machine starts to feed paper after an interval of S1 (Feeding wait mode [7]) after one
of the conditions below has occurred. However, the machine automatically starts to feed
paper if one of conditions below does not occur for 300 seconds after the machine has
