Maintenance plan
Depending on the consumables used the terms for cleaning and maintenance procedures can be
different. A fixed service plan can only be rolled out after observation. A possible service and
maintenance plan could look like described below:
Example service plan:
A)
Once each shift:
Cleaning of nozzles with a cleaner soaked cloth and a purge.
B)
Cleaning of nozzle plate with cleaning needle or ultrasonic bath when particles clog
the orifices.
C)
After a longer period out of service the print head needs to be cleaned as described
in chapter
D)
Should the print quality not be OK after cleaning please send the print head back to
REA Elektronik for in house service.
The maintenance plan has to be adapted to your
individual needs. Should you need any assistance in
setting up such a plan feel free to contact us.
9.3
Flushing of print head
To swap ink types or when putting the printing system out of operation for a longer period of time
the print head needs to be flushed. For flushing procedures the cleaner corresponding the ink that
is processed has to be used.
Never mix different ink types and different cleaners.
Different fluids might react with each other and could
cause damage to the system. Flush all components and
hoses thoroughly before changing ink types.
