Capping Unit for Epson I3200, 4720, and 5113 Printheads – Ink Absorption, Dust Protection, Moisture Retention

This capping unit is designed for use with Epson I3200, 4720, and 5113 printheads in industrial inkjet printing systems. It supports printhead maintenance by providing sealed protection during idle and cleaning cycles.

Primary Functions

Ink Absorption: The porous foam core absorbs residual ink from the nozzle plate during automatic cleaning, helping to resolve minor nozzle clogs and maintain consistent ejection performance.

Dust Prevention: Forms a physical seal over the printhead surface when not in use, blocking dust, paper fibers, and contaminants from entering the nozzle area.

Automatic Moisturizing: Creates a stable micro-humidity environment to prevent ink from evaporating and crystallizing in the nozzles during standby periods.

Compatibility

Printhead Models: Epson I3200, 4720, 5113

Capping Standards: CSG11 (I3200), CSG18/CSG21 (4720), CSG25 (5113)

The unit is engineered to match the nozzle plate geometry and sealing requirements of these printhead types.

Design Features

• High-porosity absorption pad for efficient ink collection
• Precision-molded housing for accurate alignment
• Elastic sealing lip for reliable airtight contact
• Chemically resistant materials compatible with aqueous, eco-solvent, and UV ink environments
• Designed for integration into automated head maintenance systems

Application

Suitable for wide-format printers used in digital signage, textile printing, UV flatbed systems, and industrial decoration. Ensures long-term printhead reliability and reduces downtime due to nozzle blockages.
