did you contact the vendor that sold you the printer. With my 1st HAP printer, a Z3100 i had several problems related to firmware that i could not resolve. I called up the vendor and complained, about the printer and HPs response. The vendor sent out his technican and spent 5 hours(for free) getting things worked out. I eventually got HP to extend the buy back period an extra 2 months. I now have a Z3200 and this one has been nearly trouble free, and when service was needed it was quick and painless.
