Hello Alberto,

I have several of these units but must confess that I never opened one. Doesn't seem difficult though. I found a picture of the inside on this website from the Netherlands: http://www.vintage-calculators.nl/P1000679as.jpg

You can see that there are four (!) cables coming from the secondary side of the transformer which either means three different voltages of two completetly separate supplies (which would be rather uncommon I guess). I don't think it will be easy to find a transformer of the correct size with the exact same windings. You will probably need to get one made...
However if you are lucky Ti used the same transformer for 110 and 220V and it actually has two primary windings. This is not visible in the picture above and will of course require to open the printer and remove the transformer...
