Digital BW, The Print

both ink light are on and the paper light is flashing - supposedly 
this signifies a paper jam but there is none.

I tried re-setting the rom - by disconnecting the usb cable, holding 
paper and ink buttons in and switching on - waiting 5 sec (until the 
paper light flashes, then release both buttons and press the paper 
button once.

No apparent reason for this, it worked ok yesterday but displayed 
these symptoms today.

Alas, no luck. I'm jammed & can't print :-( 
Any ideas?
