 |
|
I have a Super Twin Star including RAM Pack and PCE adapter. Unfortunately the unit does not power on. I tried to power it with a 9 Volts 1A center negative psu (which works fine with every other copier).
I opened the unit and checked the wires. Everything seems to be ok. There is a small PCB with 2 transistors. These get warm when the psu is connected. So the power seems to flow 
Any idea what's wrong with the system?
Furthermore has anyone a manual for it? Which button is the power button? I assume it's the triangle button on the right.
I'd be happy about a few hints. Thanks. |
