embarking on a ressurection of a 7800 that has sat for some years. Even though purge fluid was loaded, there were several nozzle problems before shutdown. It had been a Piezo printer that worked fairly well before sitting.
Hoping some experienced piezo/ printer doctors here may have some input.
I plan to do several piezoflushes, instal new dampers, thoroughly clean cap and wiper, or replace if necessary.
Order of things- dampers first then flushes? The reverse? Maybe force fluid through the lines when they are disconnected for damper replacement?
The head, while the dampers are off for replacement, would it be useful to syringe some piezoflush into the head, maybe let that soak… etc., even force fluid through? Is there a possibility of damaging the head?
Thanks for any advice, Tyler
