Wanted to share this from last week. Lost my print head Mutoh ValuJet 1624x last week after having it in top condition for 5 years.
Last week. Nozzle check – all lines present (after 5 years use)
Switched on printed. Did a clean. Lost the yellow nozzle check, then the cyan as well. Took printer apart. With syringe tested head. Head gone. End of story.
WHAT WORRIES ME: For these internal channels / pipes to break and join together (yellow and cyan in my case) this can be improved by manufacturer with thicker internal wall. My printer looks new, not abused. To lose head like this is shocking.
