Dear Kind Folks!
Gaaah. So I managed to get the nozzles unclogged with Simple Green and now after printing a few pieces, I'm getting this code :
MAINTENANCE REQUEST CODE - 0010 - CHECK MANUAL
Of course, it's the weekend and I can't call Epson and I'm furiously catching up on my production.
I found this online: http://www.largeformatsupport.co.uk/4900.html
It says: MAINTENANCE REQ - 0010 - Communication with the AID Board is not established.
Arrgggh what is an AID board?
