Backup RAM malfunction • Data written in the backup memory differs from what is recorded
NOTE
• The punch unit detects punch-related malfunctions and notifies the finisher of any
malfunction detected.
• The stapler drive home position sensor (PS19) is not blocked
even after the lapse of a given period of time after the clinch
operation has started.
• An encoder clock input is not detected within a given period of
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.
• No response is received to a request made by the finisher within
a given period of time during initial communications.
• No response is received to a request made by the finisher within
a given period of time during ordinary communications.
• There is no match in the checksum values of the backup data as
checked twice.
• The 24 V power source of the punch unit is OFF when an opera-
tion request is made from the finisher.
• The side registration home sensor (PS2) is not unblocked even
after the lapse of a given period of time after the punch side reg-
istration unit has started moving from its home position.
• The side registration home sensor (PS2) is not blocked even
after the lapse of a given period of time after the punch side reg-
istration unit has started moving from a position not the home
position.
• The home position is not detected within a given period of time
after the punch motor has been rotated a half turn.
• An encoder clock input is not detected even after the lapse of a
given period of time during operation of the punch motor.
• The setting value calculated during the initial operation falls out-
side the threshold value range.
• The light receiving voltage is 2.5 V or less when the illuminating
voltage is set to 4.4 V.
• The light receiving voltage is 2.5 V or more when the illuminating
voltage is set to 0 V.
• The illuminating voltage setting is 4.4 V or more after the adjust-
ment has been made.
