T-9-4Enter 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.9.2.1.4 Fixing film edge cooling control 0014-5559Color iR C3380G / Color iR C2880G / Color iR C3380i / Color iR C3380 / Color iR C2880i / Color iR C2880 / iR C3480 / iR C3480i / iR C3080 / iR C3080i / iRC2550In 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 fixingfilm 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 fixingfilm edge. Thanks to this, it prevents film deterioration by heating of the fixing film edge.1. Shutter Fan Position Drive ControlThe 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-closeto 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, homeposition).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) detectstemperature 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 theshutter is moved to a position corresponds to the paper size chosen.F-9-6MEMO:Entry -2 -1 0 1 2Temperature at Return 125 138 150 175 200Time Before Return 90 90 30 30 30PS28M15A4R LTR-R B4 EXE K8 LTRPS29M15FM7PS29PS28FM6Shutter Light-Blocking Platedirection of movement
