Ink Capping for Epson i3200/4720/5113 Printhead – Sealing Unit for Nozzle Maintenance

This ink capping unit is designed for Epson i3200, 4720, and 5113 printheads, providing reliable sealing performance in industrial inkjet printing systems. It plays a critical role in daily maintenance by protecting the nozzle plate from contamination and drying during printer standby or cleaning operations.

Primary Functions

Ink Absorption: Effectively absorbs residual ink from the nozzle surface during automatic or manual cleaning cycles, helping to clear minor blockages and restore consistent ink ejection.

Dust Prevention: Forms a tight physical seal over the printhead when not in use, preventing dust, paper fibers, and airborne particles from entering the nozzle area and causing clogs.

Automatic Moisturizing: Maintains a sealed, humid micro-environment around the nozzle plate to prevent ink from drying out during extended idle periods, ensuring smooth startup and stable print quality.

Compatibility

Printhead Models: Epson i3200 (CSG11), 4720 (CSG18/CSG21), 5113 (CSG25)

The unit is engineered to match the nozzle plate geometry and sealing pressure requirements of all three models, enabling cross-compatibility in multi-head printer platforms.

Design Features

• High-porosity absorption pad (foam or mesh) for efficient ink wicking
• Precision-molded housing ensures accurate alignment with the printhead
• Elastic sealing lip provides consistent contact without damaging the nozzle surface
• Durable materials resistant to aqueous, eco-solvent, and UV inks
• Designed for integration into automated capping and maintenance systems

Application

Suitable for wide-format inkjet printers used in digital signage, textile printing, UV flatbed systems, and industrial decoration. Helps extend printhead life and reduce downtime caused by nozzle clogging or dry-out.
