To prevent these symptoms, one Arch Sensor (PS11) located at the inlet of the Fixing Unit detects the slack of paper and adjusts
the the rotation speed of the Fixing Motor. This keeps an appropriate level of paper slack.
The Arch Sensor (PS11) detects a paper arch between the transfer nip and fixing nip, and changes the drive speed of the Fixing
Motor as follows:
1. When the paper leading edge passes 23 mm in front of the Fixing Nip Assembly, the Fixing Motor drive speed is decelerated
by 4.5% (for A4/LTR plain paper) relative to the process speed. The decelerated speed is maintained until the paper leading
edge passes over 12 mm from the fixing nip.
2. When the Arch Sensor (PS11) is ON:
After the Arch Sensor has been detected ON for consecutive 20 ms or longer, the Fixing Motor drive is accelerated by
0.1% (for A4/LRT plain paper) relative to the process speed.
When Arch Sensor (PS11) is OFF:
After the Arch Sensor has been detected OFF for consecutive 20 ms or longer, the Fixing Motor drive is decelerated by
3.9% (for A4/LTR plain paper)relative to the process speed.
3. The Fixing Motor drive speed is switched as the Arch Sensor (PS11) repeatedly turns ON and OFF.
4. When the paper trailing edge passes 20 mm in front of the secondary transfer nip area (for A4/LTR plain paper), the Fixing
Motor drive returns to constant speed.

■ Fixing Unit Detection
During warm-up rotation (at power-on/recovery from sleep mode/closing of the cover), the Fixing Unit detection signal is input to
the DC Controller to detect the Fixing Unit.
When it is judged that the Fixing Unit is absent, the machine displays the message "Set the Fixing Unit." on the Control Panel
and stops operation.
