Regular Mimaki maintenance keeps nozzles firing and saves ink, media and print heads. The basics are the same on every Mimaki: test print daily, keep the wiper and cap clean with the right Mimaki maintenance liquid, and replace wipers, caps and dampers before they wear out.
Which Mimaki maintenance liquid do I need?

Always confirm with your printer manual or call us with your model and ink.
Mimaki daily and weekly maintenance
- Every day: print a test pattern before you start, and keep the printer powered on so its automatic cleaning runs.
- Every week (or as the manual says): clean the wiper, cap rubber and the area around the head with a cleaning stick and maintenance liquid; check and empty the waste ink tank.
- When printing white: shake white ink daily and use circulation if your model has it.
- Before a long shutdown: follow the storage cleaning in your manual so ink does not dry in the head.
Mimaki wipers, caps and dampers
The Mimaki wiper scrapes ink off the nozzle plate after cleaning; replace it when it is torn, hard, or leaves streaks. The cap seals the head when idle; replace it when the rubber lip is damaged. An ink damper steadies ink pressure just above the head; replace it when one color keeps dropping out after cleanings, or the damper is dented or leaking.
Mimaki maintenance FAQ

How do I change a Mimaki JV33 damper?
Power down, close the ink supply, and move the carriage out for maintenance. Disconnect the damper from the head and the ink tube, fit the new damper, then run an ink fill from the menu and print a test pattern. Wear gloves and keep ink off the head connectors.
How do I check the wash liquid on a Mimaki?
On models with a washing liquid cartridge or bottle, the printer shows its level on the panel and warns when it is low or expired. Replace it with the maintenance liquid listed for your ink type.
How often should I replace the Mimaki wiper?
Replace the wiper when it is torn, hardened or leaves streaks, and keep a spare. A worn wiper is one of the most common causes of missing nozzles.
