I wouldnt connect your printer to the computer just yet....Have you tried to push the tray all the way back in til it clicks then hit the power button? If so does it run its warm up sequence? Has the printer ever ran the warm up sequence?
i think there is a troubleshooting guide on the net for these printers....i ll see if i still have it on my computer..
Mine is a 1400 not 1430 but i was told the 1430 can be more difficult....EKRIp does have a trial... I would email them for the trial and see if you get anywhere through that software...
