Hi,
So when you power on the printer, nothing happens? Is the power plug firmly inserted into the power brick? Was this a kit you assembled or purchased assembled?
Double check the connections going to the print head, those wires shouldn't pop out but it could happen....also, under the printer, is everything plugged into the electronics board?
More details please!
If it was working but was idled for some time, it should just work. BUT...use some sewing machine oil (you can get it at Sears, WalMart, etc) and lightly lubricate the rods. I left my machine idle for a few months and when I tried to do some printing, it was VERY noisy. Cleaning and oiling the rods fixed this.
