Resets the temperature at which job is restarted and the amount of time required before the restart when the paper size is changed to larger sizes (A4R or wider)

during down-sequence control.

Enter a greater entry if reducing the downtime during paper size switchover is desired. Enter a smaller entry to prevent hot offset immediately after the switchover.

In the case of continuous prints of the size paper (the width less than A3NC, and as large as A4NC or more), if the sub thermistor detection temperature of the fixing

film reaches to the specified temperature, it executes temperature control to prevent the edge temperature rise by feeding air from the 2 cooling fans to the fixing

film edge. Thanks to this, it prevents film deterioration by heating of the fixing film edge.

1. Shutter Fan Position Drive Control

The duct that passes air has a shutter mechanism to enable sending air to the ideal area of the fixing film by opening/closing the shutter by 6 steps (from full-close

to full-open) according to the paper size. The shutter opening/closing position that corresponds the paper size has 7-point (A4R, LTRR, B4, EXE, K8, LTR, home

position).

Open/close positions of the shutter is detected by the fan shutter HP sensor (PS28) and fan shutter position sensor (PS29). When sub-thermistor 1 (TH2) detects

temperature listed below, fan shutter motor (M15) is rotated until the fan shutter HP sensor detects the shutter. And then, positive rotation of the fan shutter motor

(M15) is initiated and the shutter is moved to a position corresponds to the paper size chosen. The fan shutter motor is reversely rotated in the last-rotation period,

and the shutter is returned to the home position. If paper size is changed during continuous printing, the shutter is returned to its home position first and then the

shutter is moved to a position corresponds to the paper size chosen.
