mounting screws were loose
[Case in the field]
Description
During punch or non-punch jobs, the Professional Puncher drive does not turn on and the jam code 1F77
is logged. The Professional Puncher controller has 3 lite green LED's, indicating AC voltage is present and
the power on remote signal is being received from the Integration unit.
Field Remedy
In this case, the Professional Puncher front door latch mounting screws were loose and tightening the
screws corrected the problem. The following image shows the latch on the punch door.
The hook on the main body that the door latch catches may cause the same problem. The following image
shows the hook on the punch front frame.
