The danger with too low a voltage is the low voltage circuit kicking in which
will stop whatever is happening at the time. The unit uses a 5 cell NiCad pack,
5 * 1.2V = 6V. A freshly charged pack might be more like 6.5V, so using a 6V
regulated supply should work.
The danger with devices of
Thanks a lot for that, Jeff. I believe I actually used a switching 5v
supply, which turned out to be enough.
Would it be a safe-ish strategy to aim for a regulated/switching power
supply that hits the lower end of the battery pack's voltage? I had
imagined it would just draw as much current as it
Was perusing the archive and noticed this thread, I can confirm the PC-2
plotter runs happily without a battery if you upgrade the power supply.
Just get newer one with the same polarity and voltage, but higher amperage.
I think mine was 2A, but *definitely* double check that polarity!
Also,
Thanks all for the recommendations and links. Looking forward to getting
this all up and running.
Esp appreciated as working from home/ stir-crazy due to mostly stuck inside.
Next on the project list does deal with my T102/ DVI so promises I'll keep
topics relevant to the group next time.
Again
Thanks Ron, that's good to know.

Hello Phillip,
Thanks much for the response.
Good to know. I thought this could be removed without any loss in
functionality. I am using a bench supply which pushes more amps than the
wall wart if it

Note that you can use a more powerful AC adapter to power the printer/PC-2. I
have a 2A one for my set up. Then you don't need the batteries at all.
Hello Phillip,
Thanks much for the response.

wall wart if it matters.
I plan on building a pack for this anyway and will definitely see if this
helps.

I have one of those. The printer needs the batteries to function. They
provide current sinking beyond what the wall wart does.

Asking here having seen some other handhelds come up, and this seems
to be a welcoming group for all
