Error Messages (Continued)
‘Last crease is too close to the end of the sheet’
‘Double sheet detected’
‘Overlap - Probable cause, double sheet’
‘Blade Home Failure 2’
‘Warning Blade pressure may be too high’
‘NV checksum error’
This indicates that the sheet has ended too close to the last crease position. This can
be caused by the sheet being too short (mistakenly), the sensor 'seeing' through the
sheet towards the end of the sheet (damaged sheet) or some sort of sensor error
(Calibration too close).
This indicates that the double detector, (If installed), has picked up a double sheet.
This indicates that the ‘Lead Edge Sensor’ has seen a sheet subsequent to the first
one as being longer. Again this could actually be a longer sheet, OR it could be a
sensor problem (if it is a recurring problem).
This indicates that the crease blade did not get back to its home position correctly or
at the correct time. Causes, can be excessive blade pressure (suspect a double), or
Some kind of jam which caused more than one sheet thickness to be creased.
This indicates that there may be some creasing errors, and that the creasing pressure
should be checked, (also check for a double that may have got through, causing this
error).
This error may appear when the machine is first turned on. It indicates that the
checksum in the stored data (tool settings) does not match the one expected. (i.e. The
software installed in the machine has been corrupted). This problem can only be
rectified by a factory trained Service Engineer.
