In this case, the paper cut mode will be automatically changed to the Preset/Variable cut mode. It is not necessary to press the cut key at the trailing edge of the original from the 2nd copy paper. Before the 2nd original is inserted in the original table, the cut length in the cut length counter can be changed with the "+"/"-" keys within the range of the semi-synchro cut (410 mm ~ 2,000, 16.5' ~ 80.0'). Selects the speed of the original feed motor 0: 200 mm/s in returning original mode. A slower speed 1: 150 mm/s may be effective for the thinner original. 2: 100 mm/s Selects the Roll Feeder start timing, just 0: Trailing edge is after the original entrance sensor detects the detected. trailing edge of the original, or just after the 1: Original insertion original entrance sensor detects the insertion of the original. The setting change from 0 to 1 makes the first copy faster and 1 to 1 CPM increases. If the emergency stop key is pressed while the original is being transported to the scanning start position from the original insertion, it is necessary to check for paper left between the copier and roll feeder. Whichever setting is selected, the first copy and 1 to 1 CPM are within specification.
