My bother call me one day last week saying hey my printer dose not work any more so I said OK let take a look and see what up
Power supply DEAD no power output........ 30 volt power supply
Open the little power supply and found that it has a mosfet and three caps that on the hit list of BAD brands to have in a power supply
330 uf @ 35 volts 1.4 ESR reading
10 uf @ 50 volts 13 ESR reading
Mosfet was a question mark to where or not it was working or not
I first put in the Mosfet and then there was power of 29.98 volts DC
but would turn on the printer
so I put a motor that is 12 volts on this power supply the motor ran slow on the power supply
then I changed the two caps now the printer come on and works like it did when it was new
Took about 1.5 hours to fix this power supply
Mosfet $1.00
330 cap $1.00
10 cap $0.20
Shipping $7.00 there was other parts ordered
