Hi, and thanks for the offer, but I'm in Norway so not very practical. I've been in touch with Alge Norway and they reckoned a minimum of $500 plus the shipping back to Austria (but that's Norwegian prices).
So we bought a Timy2 instead - one without a printer, and I swapped the plug on the P5 that used to hang off the S4
I was just hoping that someone might say "oh, yeah, its the probably the x-y-z" and I could take a swing at fixing it (a schematic would be good, but I guess that's a big no-no).
