8.2.2.3 Target Temperatures by Mode
0011-2072
iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
This machine controls the fixing temperature according to the "media type" selected in the user mode and the "target temperature" set in the "special mode."
The correspondence between each mode and target temperature is as follows:
T-8-2
*1: Target fixing temperature at startup. When the initial temperature of the fixing unit is high, the target temperature is lowered. In the continuous copy mode, the
target temperature is lowered in 5 deg C steps.
*2: Number of sheets controlled at the initial target temperature. If it is exceeded, the target temperature is lowered. The prescribed number of sheets varies with
the paper size.
8.2.3 Detecting the Passage of Paper
8.2.3.1 Detecting the Passage of Paper
0011-1112
iR2016J / iR2016 / iR2020 / / iR2016i / iR2020i
The paper passage detection mechanism of the fixing unit is shown below.
F-8-4
If a delay jam is detected by the fixing delivery sensor (SR202), the fixing motor is stopped immediately to prevent paper from winding around the fixing roller.
