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. Product Details Specification Detail Part number M905240 (replaces SPA-0133) Component type Capping unit / cap head assembly — nozzle face seal and cleaning suction chamber Compatible printhead platform Epson DX5-based Mimaki printheads Ink compatibility Eco-solvent and solvent inks Recommended replacement interval Yearly, or sooner if seal integrity fails 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.

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 Generic Replacement vs. OEM Original Capping Unit Specification Generic Replacement (this listing) OEM Original Mimaki Fit and function Direct drop-in replacement — same seal geometry and mounting Direct fit Rubber compound Solvent-resistant rubber engineered for long service life Solvent-resistant rubber Price point Lower — significant savings over OEM Higher Availability In stock, same day shipping Often longer lead times Best for Routine yearly maintenance and budget-conscious print shops Shops requiring branded OEM parts only Mimaki DX5 Printer Maintenance Checklist • Capping unit (this listing) — replace yearly, or sooner if seal integrity fails • Wiper blade — replace with the capping unit as a single maintenance event • Ink dampers — inspect for clogging during capping station service • DX5 printhead — available separately at Digiprint USA Why Buy from Digiprint USA • Direct drop-in fit across the full Mimaki DX5-based lineup, from the original JV33/JV5 through current TS3/TS34 models • Solvent-resistant rubber compound built for long service life • In stock in Doral, Miami FL — same day shipping before 2PM EST • We also stock DX5 printheads, dampers, wiper blades, and other Mimaki spare parts — contact us to bundle your order • Ideal for Latin American Mimaki eco-solvent and solvent operations using Miami freight forwarders Browse our full range of industrial inkjet printer spare parts including printheads, dampers, and filters.

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.
