Post subject:  Printer with Step-up transformer not working
I have an HP 2100tn printer that works on 220V and I use a 500W step
up & down transformer between it and my outlet.

The other day when I turned the transformer on the printer light came
on, but then went out.

Now the transformer vibrates slight as if there is a fan on inside,
but I never noticed this when everything was working.

I'm thinking that power is not getting to my printer and I wanted to
get advice on how to narrow the problem down.

If anyone is familiar with it, I have a Fluke 8060A digital multimeter
and would appreciate ideas on what and how to check first.

Thanks.

** Errr - the fuses ?

Unplug the printer and check the AC voltage on the output of the transformer
first.

That's what I was thinking, but up until now I've only checked output
voltages from computer and arcade game power supplies with this
Multimeter, and I wanted to be sure I was doing this correctly.

I assume that I set the multimeter on 750 AC(which is one step above
it's 200 AC setting), and with the step-up transformer I am to place
one test lead into the output's ground, and one lead into one of the
other two positions, correct?

Thanks.
