Down sequence control
■ Down sequence when feeding small size paper
Purpose
To prevent temperature rise of non-feeding area in the case of continuous print of small size paper (less than A4 of length in width
direction), fixing offset or deterioration of fixing film.
Starting conditions
1. Normal down sequence
(1) When the detected temperature of sub thermistor (front) or (rear) reaches 255 deg C or higher for 400 msec continuously
during printing
(2) Whenever the thermistor detects 255 deg C or higher for 400 msec continuously, the down sequence is carried out with
the maximum 4 steps.
2. Heavy paper down sequence
(3) When one minute have passed with the heavy paper mode 1/2/3/4, or when the detected temperature of sub thermistor
(front) or (rear) reaches 255 deg C or higher for 400 msec continuously
(4) When the detected temperature of sub thermistor (front) or (rear) reaches 255 deg C or higher for 400 msec continuously
with the heavy paper down sequence, the productivity is compared with the normal down sequence. If the productivity of the
normal down sequence is low, the sequence is shift to the normal down sequence.
Operation
The fixing temperature is reduced by making wider sheet-to-sheet distance to control the temperature at lower than the target
temperature for normal print.

Completion conditions
(5) When the fixing temperature reaches 175 deg C and lower for 400 msec continuously, the productivity returns to normal.
(6) When the fixing temperature reaches 175 deg C and lower for 400 msec continuously after shifting from the heavy paper
down sequence to the normal down sequence, the sequence is shifted to the heavy paper down sequence.
