Discharge Plate Voltage?

[pronicd]

Hi, due to my stupidity I mistook a variable resistor on the main board for one on the high voltage board. Doh!

I have now fiddled with the Discharge plate voltage and I can find no information about how to set it correctly.

The machine is a Nashuatec 3913.

The only references I can find is that is should be approximately 2.2KV and in a technical bulletin it suggests marking the position before adjusting to the minimum position before doing some other adjustments (with the inference being that you should return it to the marked position afterwards - although it doesn't actually even state that).

If anyone can shed any light on how to adjust it I would be most grateful!

p.s. in my defence, both pots are marked VR101 (how difficult would it have been to give them different idents?!)

Re: Discharge Plate Voltage?

Okay, got this sorted. I completely forgot that my trusty old Avo meter had a set of high voltage inputs (up to 2.5KV), so I was able to adjust the voltage to 2.2KV using that.
I was thinking that there might be an SP code that would force the voltage on permanently for adjustment with the voltage being visible on the machines display.
However just running the machine normally was all it needed as the voltage was present for long enough (after a few runs) to set it properly.

On another matter, is there any way to get this machine to photocopy blue ink?!
It doesn't seem to matter whether on auto density or manual (set darkest) blue ink hardly reproduces at all......
