Paper Take Up Retry Control

To minimize the occurrence of a paper misfeed, 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. The paper take-up sequence is then per-
formed again. These paper take-up sequences are repeated a given number of times.
