The toner nozzle might br clogged. Try cleaning or replacing it.

This might be stupid, but are you sure you are using the right toner? I've seen wrong toner cause the exact same problem enough times I had to ask.

Fixed!!!! Printed out full smc,decided to clear nvram again without reinstalling it,now working but had to reinput all the smc values,but hey ho-result.
Cheers for all the replies

Turning SP 3-045 to off (=0) and running copies (or rebooting), then switch back to on (=1) will also reset the 'toner empty' message. Won't have to re-input values like NVRAM! Glad you got it!
