Have a Falcon Outdoor 62. We are in the same boat except mine worked until I neglected it. I am in touch with Mutoh. I will share with you what I learn.
There are only several major mechanical components that crap out due to use:
printheads, dampers, pump, capping station, supply lines and waste ink lines.
Electronics, motors, heaters, steel belt, motherboard not withstanding...most problems on the ink side.
Keep ya posted. Wanna use third party ink? Another point to ponder!
