DG-48134-J-14 - Capping guide bracket

Capping guide bracket – Mutoh ValueJet 626UF – DG-48134 (J-14)

The DG-48134 capping guide bracket (part number J-14) is a mechanical component of the capping station (Head Cap Assy) on Mutoh ValueJet UF series flatbed UV printers. It guides and holds the capping unit in position as it moves past the print head.

During standby and maintenance phases, the capping station covers the surface of the nozzles to prevent the UV ink from drying out. The guide bracket maintains the precise alignment of the caps relative to the print head, which is essential for a watertight seal. This precision ensures consistent capping and effective suction during cleaning cycles.

This part is a genuine Mutoh (OEM) component, sold individually as a replacement part for the Head Cap Assy DG-48134. It fits directly into the existing capping station without the need for any modifications.
