• Down sequence when switching paper size
Purpose:
This down sequence prevents temperature rise of non-feeding area: there can be
possible fixing offset or wrinkle of the succeeding paper due to increased temperature
of non-feeding area of the preceding paper when continuously making prints or
feeding wider length of paper than the preceding paper.

Starting conditions:
If the detected temperature of sub thermistor 1 or 2 exceeds the specified temperature
(250~260 deg C) when switching to the paper which has longer width than the
preceding paper.
Operation:
Pickup of the succeeding paper and power distribution to the heater are stopped as
well.
Completion conditions:
This down sequence is completed if any of the following conditions is satisfied:
• When the detected temperature of sub thermistor 1 or 2 reaches the specified
temperature or less.
• When the specified period of time*
1
has passed since the preceding paper went
through the fixing nip.
*1: Specified period of time differs whether the fan has cooled the preceding paper or not.
• If the preceding paper is A4R or larger and A3 or smaller (the fan has cooled the
paper)
→ 15 seconds
• If the preceding paper is smaller than A4R (the fan has not cooled the paper)
→ 30 seconds
