1. Standby Mode, Sleep Mode
In standby mode or sleep mode, the heat discharge fan (front, rear; FM1/2) is at rest.
2. Printing
While printing is under way, the fans are switched between full speed and half speed depending on whether the machine is in full speed mode or half speed mode
and the reading of the environment sensor (HU1).
- Double-Side Printing
T-10-4
- Single-Sided Printing
T-10-5
Note 1:
While the machine is in continuous printing mode, the insertion of one or more double-sided prints will start the control used for double-sided printing.
Note 2:
The printing interval covers the interval up to when the fixing motor (M3) stops rotation.
