Once we sold a bunch of 110V DL2400 Fujitsu printers, with the adapters inline on the power cable. They were still cheaper than those made for european market.

One particular printer was in a place where they had three other such printers, but these others were made for 220V. And they actually needed six or seven, so the printers were borrowed between offices quite often, and often without the power cable - any table calculator uses the same cable, right? This one was fried seven times, and went to the repair shop six times. Yes, the numbers match - it was once fried after the repair, while tested, still in the repair shop.
