Mimaki JV33/JV5 Capping Unit

The Mimaki JV33/JV5 Capping Unit (M905240, replaces SPA-0133) is a replacement cap head assembly for Mimaki's Epson DX5-based eco-solvent and solvent printer platform. It seals against the DX5 printhead nozzle face when the carriage parks at the home position, preventing ink from drying in the nozzle channels during idle periods, and provides the sealed chamber through which the ink pump creates suction during cleaning and purge cycles.

About the Mimaki DX5-Based Printer Platform

The Epson DX5 printhead has been the workhorse of Mimaki's eco-solvent and solvent lineup for over a decade, carried forward across generations of wide-format roll printers and print/cut combos. It powers the original JV33 and JV5 series as well as their successors — the JV150, JV300, CJV30, CJV150, and CJV300 — and continues in current production models like the TS3-1600 and TS34-1800A. Because the capping station design has stayed consistent across this family, a single capping unit part number (M905240) covers a wide range of Mimaki machines spanning multiple generations.

Why Does the Capping Unit Need Replacing?

When the printhead carriage parks at the home position between print jobs and overnight, the capping unit presses against the nozzle face to create an airtight seal. Solvent-based ink evaporates quickly on air exposure, so this seal is what keeps nozzles primed rather than drying out overnight. Every capping cycle presses the rubber cap top against the nozzle plate, and over months of daily use the rubber compresses, hardens, and picks up dried ink residue along the seal edge. Once the rubber loses its shape or ink builds up on the contact surface, the cap can no longer form a complete seal — air reaches the nozzles during idle periods and ink dries inside the channels. At that point, cleaning and purge cycles also lose suction, since the capping unit doubles as the sealed chamber the pump draws through, so nozzles that would normally recover with a standard cleaning cycle stay blocked instead. Technicians who keep running cleaning cycles on a worn cap frequently waste ink and still see the same nozzle dropout return within days, mistaking it for a printhead problem when the capping unit is the actual cause.

Signs the Capping Unit Needs Replacing

• Nozzle dropout appearing after idle periods — cap no longer sealing nozzle face

• Cleaning cycles failing to recover nozzles — insufficient suction from a failed seal

• Ink drying or crusting on the cap top surface — preventing correct seal contact

• Visible cracking, deformation, or hardening of the cap rubber

Frequently Asked Questions

What is the JV33/JV5 capping unit (M905240)?
The M905240 capping unit seals the DX5 printhead nozzle face on Mimaki JV33, JV5, and related solvent printers during idle periods — preventing solvent ink from drying in the nozzle channels — and provides the suction chamber for cleaning and purge cycles. Replace it yearly, or whenever the seal is worn or compromised.

Which Mimaki printers is this capping unit compatible with?
This part fits the full DX5-based Mimaki lineup, including the JV33, JV34, JV5, JV150, JV300, CJV30, CJV150, CJV300, TPC-1000, and TS3/TS34/TS5/TS500 series. It replaces the original Mimaki part number SPA-0133.

Is this an OEM part or a generic replacement?
This is a generic replacement capping unit, not an original Mimaki-branded part. It uses the same seal geometry and mounting as the OEM cap head assembly, made from solvent-resistant rubber, and installs as a direct drop-in replacement at a lower cost than OEM with faster availability.

How often should the capping unit be replaced?
Digiprint USA recommends replacing the capping unit yearly as part of routine maintenance, or sooner if you notice nozzle dropout after idle periods, failed cleaning cycles, ink crusting on the cap top, or visible cracking and hardening of the rubber — any of which indicate the seal has failed.

Do you ship this capping unit to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Digiprint USA is the closest US supplier to Mimaki DX5-based printer operations in Colombia, Mexico, Brazil, Peru, Chile, Argentina, and the Caribbean.
