I3200/4720/5113 Capping (Vertical Type – Aluminum Mesh) – High-Durability Seal for Industrial Printheads

This vertical-type capping unit features a rigid aluminum mesh core, engineered for use with Epson I3200, 4720, and 5113 printheads in industrial inkjet printers. Designed for upright installation, it delivers superior durability and consistent ink management under high-frequency operation.

Primary Functions

• Ink Absorption: The aluminum mesh structure wicks residual ink from the nozzle plate during cleaning cycles, effectively clearing minor clogs and maintaining stable ink ejection.
• Dust Prevention: Forms a tight seal over the printhead when idle, blocking dust, debris, and airborne particles from entering the nozzle area.
• Automatic Moisturizing: Maintains a sealed, humid micro-environment to prevent ink drying during standby, reducing startup failures and nozzle misfiring.

Design Specifics – Vertical Type with Aluminum Mesh

Installation Orientation: Optimized for vertical mounting (90°), commonly used in compact or space-constrained printer designs.

Core Material: Aluminum mesh – offers high mechanical strength, excellent heat dissipation, and long-term resistance to compression set.

Advantages of Aluminum Mesh:

• Resists deformation under repeated cap actuation
• Provides uniform capillary action for consistent ink absorption
• Easily cleanable and reusable in high-utilization environments
• Less prone to saturation and microbial growth compared to foam
• Conductive properties help reduce static buildup

Sealing Interface: Integrated elastomer lip ensures full contact with the nozzle plate while protecting sensitive orifice surfaces.

Compatibility

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

Capping Geometry: Matches CSG11/18/25 sealing profiles with adjustable alignment design

Mounting Type: Vertical (designed for side-mounted or upright capping stations)

Application

Ideal for industrial inkjet systems requiring high reliability and extended service life, including:

• UV flatbed printers
• Hybrid roll-to-roll signage systems
• Textile and dye-sublimation printers
• Custom-built digital decoration machines

Commonly used in environments with high print volume, frequent cleaning cycles, and demanding maintenance schedules.
