At this time, as MC203 (registration) turns off, the sheet is pressed against the conveyance rollers /U/L to form a loop.
MC203 turns on when a specified time has passed since PS201/PS206 turned on, and the drive force of M203 is transmitted to the conveyance rollers /U/L. This causes the sheet whose bend is corrected by loop formation to be conveyed into finisher. a Input signals 1 PS201 IN (PS201 to PIDB) Detection signal of sheet passage on upper tray L: Sheet passed H: Sheet not passed 2 PS202 IN (PS202 to PIDB) Detection signal of no sheet on upper tray L: Sheet detected H: Sheet not detected 3 PS203 IN (PS203 to PIDB) When the sheet turns PS206 off, MC203 turns off after a specified time.
With the same timing, MC203 changes its rotating speed to low-speed and comes into feeding operation for the next sheet. Detection signal of sheet setting on upper tray L: Sheet detected H: Sheet not detected 4 PS204 IN (PS204 to PIDB) d Detection of sheet size Detection signal of upper limit of up/down plate/U VR201/VR202 (sheet size/U/L) detect the sheet width. L: Positioned at upper limit Sheet length is detected by the combination of PS203/PS208 (sheet setting/U/L) and PS212 (sheet size/L).
