I'm experiencing a problem with a 4200n printer. The printer displays two rows of asterisks and no status lights.

After resetting the printer it will go through the normal post, memory status check 64K then all status lights go blank and the astericks will display no ready indication. Unable to do anything else with printer.

Removed jetdirect restarted and received load file and execute. Pressed the check mark then receive a download file message. Unable to progress any further. Powered off reseated everything and restarted back to the astericks. Help if you can please!!!
