Hi,
It's incredible... but i'd just solve this problem
Please be aware.... it seems that when i was cleaning my printer i accidentally moved the case of the main button slightly to one side... and this leaves the main button without working... but only it dissables the press action and not the dial action...
This of course leaves the printer innaccesible...
So, please be aware of this...
I solved it... taking out the main button, loosing the case... re-aligned the case...and tighten it with the screwdriver and thats it...
Of course that you will fell that the mechanical Click is very different... when it works... and when it doesnt.. the issue is that you still have a slight click when it doesnt work.... so that confuses you.... but if this happens re-align again until you see that the mechanical click is really good.. and there you go!!!
Thanks a lot...
