Hey everyone. I recently acquired a zcorp z400 from Dalton State College. As recently as 2 months ago it was used weekly and cleaned after every use. The last 2 months it hasnt been used. I dont know anything about these. It powers on and scrolls through a bunch of commands but stops and says binder tank not filling. Im positive its an easy fix i just dont have a clue where to start. If you are interested in purchasing for $760 contact me at jpgantt78@gmail.com. It is in good cosmetic conditions. If it requires shipping we can work something out bc the only means I have would be expensive. Also, i have plenty of current pics upon request…thanks! (Local pickup encouraged - Atl GA)
