I bought a printer from China that stopped working a number of months ago. I have had a new printhead and motherboard installed already but no printing. It is an ACHI A3. It uses an Epson 800 (or L800?) Printhead. You can find the printer online at Ebay and Amazon. I have the specs I can send. Any advice on someone who can fix it? I paid $3500 and have had troubles since the day I got it. Lesson learned, buy American!!
