Fuji Acuity Old Printheads

[Jesse P]

Hello, Does anyone know of a way that you can clean old print heads after they've been replaced and the old ones have been sitting out for a bit? we got all new print heads and now the old ones have dried but id like to try and salvage them. Any suggestions ? or know of anyone who does this ?


Thanks in advance

NMP is the preferred toshiba head cleaner here.

Many years ago I was cleaning 6 CA3 heads (taken from the oldest Acuity printer model) in the ultrasonic cleaner using original flushing solution. The result was perfect - 100% nozzles recovered, but after 10 months all these printheads died within 20 days. Generally they don't like ultrasonic cleaners, sitting in the flush etc. It's random - you can get result like me or you can kill the head immediately. Since than I don't do it anymore, especially when we talk about CE2 heads. Problem is that the flush doesn't dissolve cured ink or sediments. It's possible to find more aggresive fluid, but it will damage the head itself.
