Question about HP LaserJet 4345mfp Printer
HP Laserjet 4345MFP
Backlight on printer display does not light.
Counts up the 256MB memory then HP logo (3 sizes) appears (just visible)
The 3 lights keep cycling on the display. Thats it, does nothing else.
It has been left overnight and continues to display the logo and cycling 3 lights.
Rear DC Cont Fan is turning. No other fans or activity with machine.
When ADF/scanner/mfp or hard disk are disconnected it does recognise this and throws an error and asks for reboot.
I have tried cold reset, nvram init. and hard disk init. but no difference.
