DX7 UV Ink Dampers — 20-Pack

This 20-piece set supplies replacement dampers for DX7 printheads on compatible wide-format UV printers. Each unit features a 4x3mm connection with an integrated nut for secure installation. The parts are new and intended for routine maintenance or printhead servicing.

Replaces worn or clogged dampers on listed models

The pack restores ink flow on Witcolor Ultra 9100, Ultra 9200, Xuli, Taimes, Titanjet, Skycolor and Aifa machines using DX7 heads. It is not suited for printers with different printhead interfaces or for users needing individual dampers rather than a bulk set.

Questions about this item

What printhead models does the 4x3 mm damper with nut fit?

The damper is designed for Epson DX7 printheads and matches the 4x3 mm port size used on Wit Color Ultra 9100 and 9200 printers.

What is the correct way to seat the damper on the DX7 printhead, and what step is often missed?

Push the damper straight onto the printhead inlet until the nut threads engage, then tighten the nut by hand until snug — skipping the hand-tighten step causes air leaks.
