5050
5050=PrintGo distance is
shorter than Print length
The print distance specified in the JobEditor
between two print is shorter than the print
itself (i.e. the next print drops into first one).
Workaround: increase the PrintGo distance
Increase the PrintGo distance or
reduce stroke distance of the print
job.
5051
5051=Error.
A PrintGo occured while a
print was in progress. So
prints will be lost.
During an ongoing print, the next PrintGo
signal has been already received i.e. the
print out is longer than the distance between
two Print Go.
1. Adjust the print go sensor that
one product is sending only one
signal.
2. Reduce the distance from
sensor to print head.
3. Use print go hold function

overload.
"An overload situation of the charging
voltage amplifier (current)
Possible causes:
1. Short circuit on charge voltage line
(possibly head)
2. Coaxial cable or chassis under deflection
unit "flooded"
(check coaxial cable impedance, ohmic
resistances typical error <1MOhm
