Important Notice
To prevent costly buyer return requests, it is critical to explicitly state what this head does NOT fit:
This is the MS Italy proprietary variant complete with the factory MS head cable harness. It WILL NOT FIT and is NOT interchangeable with the "Standard" or "EFI Reggiani" versions of the KJ4B-0300 printhead. Do not buy this if you own a non-MS machine (such as EFI Reggiani, DGI, Homer, or Hanway). Additionally, this is an Aqueous (Water-Based) printhead—it is completely incompatible with UV or Solvent ink setups. No returns will be accepted if the factory seal is broken due to incorrect compatibility ordering.
