i cant find the user manual on the net and i don't know what happened to mine, i don't think it was a pdf when i had it.
what do you hope to do with it.
as a cutter i still use my 10 year old jx every day its still superb
as a printer it has not printed anything for 7 years since the day i got a epson 9500.
if i remember your drops of ink only is a poorly primed system but the carts were so unreliable.
was it working before you got it
