YINGHUA 10PCS DX6 UV Ink Damper (A) printer

10-Piece UV Ink Damper Kit

This pack contains ten DX6 UV ink dampers built from PP material. They are designed as replacement parts for large-format printers that use solvent, dye or pigment inks. The dampers fit a wide range of Forepson and Mutoh models including the 4900, 7900, 9900 and VJ1618 series. Print shops maintaining multiple compatible machines can standardise on this single part number.

Tool-Free Swap with Filter Care

Installation is a straightforward push-fit into the existing damper seat on the print carriage. The integrated imported filter handles negative pressure to prevent ink drop-out, but it must seat squarely or air bubbles will form. Technicians should purge the line fully after fitting; trapped air is the most common cause of missing nozzles on the first test print.

Steady Flow During Long Runs

The filter media maintains consistent negative pressure across extended print sessions, keeping ink delivery stable when the heads fire continuously. This reduces the frequency of mid-job cleaning cycles on high-coverage work such as banners or textile rolls. The PP housing resists solvent attack, so the damper does not degrade or leak after weeks of aggressive ink exposure.
