PAPER FEED Q3228A 1.2.3 Original size detection A. Normal copy mode Main scanning direction is detected by the resistance value of the size VR (VR301) interlocked with the guide plate position on the paper feed tray. Sub-scanning direction is detected by the combination of the original size sensor/S (PS309) and original size sensor/L (PS310) when they are turned on and off. B. Mixed original copy mode Maximum original size in the main scanning direction is detected by the resistance value of the size VR II UNIT EXPLANATION (VR301) interlocked with the guide plate position on the paper feed tray.
Sub-scanning direction is detected by the time when the original passes by the timing sensor (PS302). Allowed size combinations are as shown in the table below.
