I3200/4720/5113 Capping (Vertical Type – Plastic Mesh) – For Consistent Nozzle Sealing & Ink Management

This vertical-type capping unit features a plastic mesh structure designed for use with Epson I3200, 4720, and 5113 printheads. Engineered for upright installation orientation, it provides reliable nozzle plate sealing and efficient ink management during idle and cleaning cycles.

Primary Functions

Ink Absorption: The plastic mesh core effectively wicks residual ink from the nozzle surface during cleaning, helping to clear minor blockages and maintain stable ejection performance.

Dust Prevention: Forms a tight seal over the printhead when not in operation, preventing dust, paper fibers, and airborne particles from contaminating the nozzle area.

Automatic Moisturizing: Maintains a sealed, humid micro-environment to prevent ink drying during standby, reducing startup failures and misfiring.

Design Specifics – Vertical Type with Plastic Mesh

Installation Orientation: Designed for vertical mounting, suitable for printers where the capping station is positioned on the side or upright rail.

Core Structure: Utilizes a rigid plastic mesh (as opposed to foam) for controlled ink absorption and improved structural stability under repeated compression.

Advantages of Plastic Mesh:

• Resists deformation over time
• Offers consistent capillary action for uniform ink removal
• Easier to clean and maintain in high-utilization environments
• Less prone to saturation compared to traditional foam pads

Sealing Interface: Precision-molded elastomer lip ensures full contact with the nozzle plate while protecting delicate orifice surfaces.

Compatibility

Printhead Models: Epson I3200 (CSG11), 4720 (CSG18/CSG21), 5113 (CSG25)

Capping Standard: Adapts to CSG11/18/25 sealing geometries with adjustable alignment design

Mounting Type: Vertical (90° orientation relative to printhead travel direction)

Application

Ideal for industrial inkjet systems utilizing vertical capping mechanisms, including certain UV flatbed, hybrid roll-to-roll, and custom-built printing platforms. Commonly found in environments requiring long-term reliability and reduced maintenance frequency.
