Mimaki UJF-3042 Cap Assy – M012112 Replaces M011160/M010546

Mimaki UJF-3042 Cap Assy MP-M012112 Description

The Mimaki Cap Assembly (Part No.: M012112) is a 100% genuine OEM component engineered specifically for the Mimaki UJF-3042 UV flatbed inkjet printer. This upgraded assembly replaces legacy part numbers M011160 and M010546, offering improved design, enhanced sealing performance, and greater durability in high-utilization environments.

As a core element of the printer’s automatic maintenance system, the cap assembly ensures long-term printhead reliability by forming an airtight seal during idle periods and enabling effective vacuum cleaning cycles.

Primary Functions

Airtight Capping: Prevents oxygen and ambient UV light exposure at the nozzle plate, stopping premature curing of UV ink—a common cause of clogs and misfiring.

Nozzle Protection: Maintains a stable, humid micro-environment to preserve ink fluidity and prevent drying during standby.

Effective Ink Suction: Interfaces seamlessly with the maintenance pump to remove degraded ink, air bubbles, and debris during cleaning cycles.

Contamination Shield: Blocks dust, substrate particles, and overspray from entering the printhead area during non-printing operations.

Key Features

Genuine Mimaki OEM Part: Guaranteed fit, function, and compatibility—no risk of leaks or misalignment

Direct Replacement: Upgraded part M012112 supersedes M011160 and M010546—ideal for retrofitting older systems

UV-Resistant Materials: Sealing components engineered to withstand aggressive UV-curable inks and repeated exposure

Precision Fit: Ensures full-face contact with the UJF-3042 printhead without causing wear or damage

Durable Construction: Built for thousands of actuation cycles in industrial print environments

Plug-and-Play Installation: No modifications required—direct replacement for existing capping station

Compatibility

Primary Model: Mimaki UJF-3042

Replaces: M011160, M010546 (verify physical fit if used in earlier revision units)

Note: Not compatible with UJF-3042MKII, UJF-6042, or other UJF series models without verification. The M012112 is specific to the original UJF-3042 platform.

Application

Recommended for:

• Scheduled maintenance and preventive replacement
• Printhead replacement or system rebuilds
• Resolving suction errors, cap seal leaks, or frequent nozzle checks

Ideal for UV flatbed print shops, industrial decorators, service technicians, and maintenance teams who require authentic components to ensure maximum uptime, print consistency, and printhead longevity.
