Just for your amusement - and to help people who might once grep the list archives to find the solution if they're as stupid as me... I just carried a LA120 upstairs into my screenprinting/collection room. And I wanted to test it because it had stayed many months on a pallet under a cloth. After power on it just worked fine. And than the paper ran out. It made a lot of sound with blinking and all that. So far... But when I power-cycled it - it played dead. All LEDs on and all digits lit. I was kinda confused because the digits are processor controlled. So it could not be completely dead. But why didn't it complain and blink and just SAY something?!? Severe firmware corruption? All voltages were there. No fuse blown. Nothing disconnected. The manual helped me: If the cover is open or paper out on power-on, the LA120 will just play dead. Without any further complaints. Many of you out there might know that. But I can imagine that there are some potential future victims of this behaviour: You have been warend now :-) Kind regards Philipp
