11.2.2 Controlling the Fixing Roller Temperature
11.2.2.1 Overview
The temperature control mechanism of the fixing roller is as follows:
See the next and subsequent pages for details of the temperature control mechanism for the following:
(1) at power-on
(2) in standby
(3) during printing
(4) in response to overheating of the ends
(5) in response to overheating of the fixing tension roller
(6) during recovery from low-power mode
(6) during recovery from sleep mode
11.2.2.2 At Power-On(Fixing belt less than 100 deg C)
While the machine is starting up, the fixing start-up sequence is based on the mechanism used when the fixing
belt temperature is less than 100 deg C.
In fixing start-up sequence, the fixing belt target temperature and the pressure target temperature are used as
target temperatures while the machine starts up, supplying the IH heater with power to turn on the pressure
heater until the start-up end condition*1 is satisfied, at which time the machine moves to standby sequence.
The machine also drives the fixing motor while it starts up to rotate the fixing belt and the pressure belt at 32
mm/sec. The pressure belt is not in contact with the fixing belt (i.e., away).
Note 1: The condition of setup completion varies depending on the environment and model (iR C5180, iR
C4580, or iR C4080). See the following:
