Send the old part label, printer model, photos of the installed area and the current fault symptom if you are not fully sure. Pumps, filters, valves and tube assemblies can look similar but may use different connectors, flow direction, pressure rating or ink compatibility.
Install with a trained technician or experienced operator. After replacement, check ink flow, air leakage, suction, pressure, filter direction, tube routing and pump/valve operation before production.
Can this fit another Mimaki model? Only if the part number or official compatibility list matches your machine.
Why do filters and valves need strict confirmation? Wrong pore size, connector type, flow direction or valve specification can cause ink starvation, leakage, pressure errors or printhead damage.
