Can anyone give me informations how tell the different ProFlow systems from each other? There are casetty systems, refillable systems, refillable systems with temperature control, casette systems with software controlled pressure regulation and refillable systems with software controlled pressure regulation. It looks like DEK does not use article numbers for these systems and does not mark the print heads differently. Or do I just don't know where to look? Are there any rules like "if it has these two connectors it is this system..."?
