A friend has inherited an AcerScan 320U scanner, but the power
supply is missing, and so is any manual that may have come with it
originally. The power input is marked 16V, but no indication
whether it's AC or DC, and if DC, what the polarity is.

Can someone who uses this scanner shed some light on this situation?
We would like to use some inexpensive wall wort, and just need to
know what to get.

Thanks very much.

George,

Acer Peripherals is now BenQ; you can purchase replacement
power adapters directly from BenQ:
