Mimaki Cap Head Assy – M905240 for JV5, JV33, CJV30 Series Printers

Cap Head Assy for JV5/JV33/CJV30 Description

This is the original equipment manufacturer (OEM) Cap Head Assembly (Part No.: M905240, replaces SPA-0133) designed for Mimaki JV5, JV33, and CJV30 series wide-format inkjet printers. As a genuine Mimaki component, it ensures precise integration with the printer’s maintenance station for reliable printhead sealing and long-term performance.

The Cap Head Assy is a core part of the capping system, responsible for forming an airtight seal over the printhead during idle periods and enabling effective cleaning cycles to maintain optimal nozzle condition.

Primary Functions

Secure Capping: Forms a precise, leak-free seal over the printhead when parked, preventing ink evaporation and nozzle drying.

Dust & Debris Protection: Shields the nozzle plate from airborne contaminants, paper fibers, and ink mist during standby.

Efficient Ink Suction: Interfaces seamlessly with the maintenance pump to support vacuum-based cleaning, removing degraded ink, air bubbles, and residue.

Printhead Longevity: Maintains a stable, humid environment at the nozzle interface, reducing clogs and misfiring for consistent print quality.
