Free Me

Often, cartridges dry out in places other than the nozzles, for example, also under the De-Bubble and in the nozzle inlet chambers. Making filling no longer possible. This results in the cartridge needing to be returned and leads to very poor revenues. This is now changing with 42 FreeMe! Make your own refills with the equipment available in your shop, such as an ultrasound and suction unit. Even heavily dried up HP ink cartridges become easily and quickly usable again with 42 FreeMe!

How it works
  • Due to its composition, this liquid attracts dry coloured in particles merges with them and passes through the nozzles and the spindle, which expand due to the ultrasound heat (45 º). This feature thoroughly cleans the rinse nozzles and not only the cartridge.

    For use in: Color cartridges

  • After opening the cartridge and having taken out the ink sponge, rinse with water and then fill the chambers with 42 FreeMe!

    ❶ Put the cartridge in the ultrasonic bath filled with U-SonicFluid and let 42 FreeMe! act accordingly.

    ❷ Place the cartridge on a paper towel. Repeat the process until you can see the imprints clear and clean. Then suck FreeMe with your suction unit (e.g Aspiramax) through the nozzles. If the print only shows pastel colors the cartridge is ready to be refilled again. Then attach the lid of the cartridge with hot glue. Suck the colours in to the print head with your suction unit until the print of the nozzles are clear.
