If absence of papercannot be detected even at once, it is judged as a delivery stationary jam.NOTE:The margin is set to 20 mm. Bounce of paper is taken into consideration for the setting.● Pickup Stationary Jam during Auto DeliveryWhen the Paper Leading Edge Sensor (PS751) detects presence of paper at 1490 (2235)msec. after the start of auto delivery, and the Paper Leading Edge Sensor (PS751) detectspresence of paper after further feeding paper for 3835 (5555) msec., it is judged as a pickupstationary jam.NOTE:The above 3835 (5555) msec. paper feed period is the difference between the paperfeed time for the maximum paper size: "5325 (7790) – 1490 (2235) msec.".F-2-30● Delivery Stationary Jam during Auto DeliveryWhen the Paper Leading Edge Sensor (PS751) detects absence of paper at 1490 (2235)msec. after the start of auto delivery, and the Fixing Delivery Sensor (PS701) detectspresence of paper after further feeding paper for 1265 (1900) msec., it is judged as a deliverystationary jam.When the Paper Leading Edge Sensor (PS751) detects presence of paper at 1490 (2235)msec. after the start of auto delivery, and the Fixing Delivery Sensor (PS701) detectspresence of paper after further feeding paper for 5100 (7655) msec., it is judged as a deliverystationary jam.● Delivery Stationary Jam during CleaningWhen the Fixing Delivery Sensor (PS701) cannot detect absence of paper within 3445 msec.following the Main Motor (M1) rotation startup after finishing the cleaning process, it is judgedas a delivery stationary jam.■ Other Jams● Fixing Wrap JamOFFONOFFONFixing Wrap Jam Detection Period910(1360)msec70(110)msecPaper Leading EdgeSensor (PS751)Fixing DeliverySensor (PS701)When the Fixing Delivery Sensor (PS701) detects absence of paper from 70 (110) msec.after it last detected presence of paper until 910 (1360) msec. after the Paper Leading EdgeSensor (PS751) last detected absence of paper, it is judged as a fixing wrap jam.NOTE:The leading-edge detection margin is 8 mm, and the trailing-edge detection margin is20 mm.The above 910 (1360) msec. accounts for 70 (110) msec. calculated from 8 mm and thetime calculated from the "121.31 - 20" mm feeding distance of the trailing edge of paperfrom the Paper Leading Edge Sensor (PS751) to the Fixing Delivery Sensor (PS701).The leading-edge detection margin is set to prevent incorrect detection of a wrappingjam during chattering at paper entry.The trailing-edge detection margin is set longer than the leading-edge margin to allowfor detection time uncertainty due to bounce of paper, etc.F-2-31
