If you have a PCB layout software package that produces Gerber photoplotter files for the artwork for the different layers, and Excellon drill-control files, try submitting a ZIP file containing them, to the freeDFM service at the Advanced Circuits link, above.
They later determined that the circuit board was fried and that a replacement board from the manufacturer would take several MONTHS to arrive. Anyway, I couple of questions come to mind that you may be able to answer: If you want to feel safe, will mostly print in full color, expect great results and are not price sensitive - go for OEM cartridges!
