I stupidly moved my laser printer with me overseas without checking whether it would take 220V. I assumed it would be like my desktop computer and accept both.
Anyway, here I am with a 110V printer in a 220V country. The label says 110V 50/60Hz.
I've opened the printer to look at the power supply, and I also found the service manual.
On the board, there is a 250V fuse, a 125V fuse, and a smaller fuse. According to the schematics, the AC input first goes through the 250V F1 fuse, then the 125V F2 fuse, then the smaller one (F3).
There is also a somewhat large capacitor that says 200V 270uF.
Do you think it's possible this power supply would accept 220V without modification, but it's not labeled as such for whatever reason? I think Sony did that on the PlayStation for instance to try and curb the grey market.
Here are pictures of the board, and the service manual.
