time during a clinch operation.
• The folding home position sensor (PS11) is not blocked even
after the lapse of a given period of time after the folding unit has
started moving from a position out of the home position during
an initial operation.
• The folding home position sensor (PS11) is not unblocked even
after the lapse of a given period of time after a folding operation
has been started during an ordinary operation.
• The folding home position sensor (PS11) is not blocked even
after the lapse of a given period of time after a folding operation
has been started and the sensor has been unblocked during an
ordinary operation.
• An encoder clock input is not detected within a given period of
time during a folding operation.
