Paper Take Up Interval Control

To minimize the occurrence of a paper misfeed due to improper paper separation, the
paper take-up sequence is temporarily halted if the paper fails to reach the Paper Take-Up
Detecting Sensor within a given period of time after the sequence has been started. After
another given period of time, the paper take-up sequence is performed a second time,
thereby ensuring a good interval between two paper take-up sequences.

Double Feed Paper Take Up Control

If double feed has not occurred, the copier starts the paper take-up sequence for the sub-
sequent sheet of paper as soon as the Paper Take-Up Sensor is deactivated.
If double feed occurs, the Paper Take-Up Sensor is not deactivated. In this case, the copier
starts the paper take-up sequence for the subsequent sheet of paper when the Paper
Leading Edge Sensor is deactivated.
