Mutoh 1204 Value Jet Lifetimes Pump

Discussion in 'Mutoh' started by Wesley Spiggle, Sep 8, 2019.

  1. I have a Mutoh Valuejet 1204. I am getting an error message that the life times pump needs to be replaced. However my ink is still printing other than the black. I can print Magenta, Cyan, and Yellow with zero issues however the black will not print.

    I do a nozzle test and out of the two blocks for black one is completely missing. Does anyone know if this is a separate issue from the life times pump error or is this due to the pump?
