Agfa Snapscan e25: AC Adaptor

I've got an old Agfa Snapscan e25 but I can't remember which one of all
the AC adaptors lying around here accompanied the scanner. Since the
output voltages vary (12V, 16V, ...), I guess I'll have to pick the right
one. But I can't find this in the documentation nor on the web. Anyone who
can help me out here?

The site I just looked at said:
Voltage Required AC 110/220 V ± 10% ( 50/60 Hz ).

Yes, the adaptors are all 110/200V input, but what should be the output
voltage? Is it that 10% ?

OK. Start with the lowest voltage adapter you`ve got say 9 or 12 volt,
and work your way up through them.

Ok, I'll try that. Would too low a voltage just make the scanner not work?

It might also result in the lamp being off-hue even if the
other electronics did work, but it is definitely safer than
overshooting the correct voltage too far. Also remember
that these lamps need several minutes to warm up to a
normalized color, a test right after it's been powered up is
not necessarily indicative of the correct color, though it
might be used for comparison purposes to prior scans you'd
made if you always scanned right after it'd come out of
sleep mode (lamp just turned on). Scanners may do a
"warmup" period but that is not long enough for the lamp to
reach best color.

It appears to use a CCFL lamp, and the typical CCFL lamped
scanner uses about 12-15V, 1-1.5A adapter, almost always a
switcher (thin and lightweight relative to an unregulated
type per same voltage and current).

The device itself should have the input required somewhere on the
device. It's a requirement of UL.

No. That's tolerance for input voltage. Meaning that in North
America, the adapter can handle 99V to 121V (ie. 110-[110*0.1] and
110+[110*0.1]) going into it without it malfunctioning.

Have a look at the adapter hole (probably in back) and at the specs
sticker (usually underneath).

The specs sticker will usually tell you what voltage and current it
actually runs on. This information is usually (but not always) also
found near the adapter hole in the device. Near the adapter hole, you
should find a symbol that will tell you what the polarity should be.
It's a symbol that looks like a ball joint. The ball indicates what
the tip polarity should be.

Of course, it's also possible that the manufacturers put absolutely no
useful information at all on the device.
