Damper Holder 4H - M504503 E302001 This is the original SeikoMimaki Spare Part Damper Holder 4H SKU: M504503 What this part is The ink damper sits in the line between the ink supply and the printhead, smoothing the pressure pulses as ink is drawn toward the nozzles and trapping air bubbles and debris before they reach the head. Stable back pressure and clean ink keep jetting consistent, so a tired damper is a common cause of banding and dropped nozzles. Specifications SKU M504503 Part Type Ink Damper Type Brand
