HOW DO HARD RESET MY SAMSUNG SCH S738C Im locked out of my samsung sch...

I've seen a few of these and the easiest fix is to replace both the blower motor speed controller/resistor and the wiring harness connector. I've tried fixing the connector but the repairs don't last because of the heat generated at the connector if everything isn't just right. You can purchase the connector, which comes with color coded pigtail wires attached, from the dealer and it's a fairly easy and permanent fix. Hope this helps and good luck!

You can get the Unlock code at reliable cost at here

You are more than likely out of magenta (red) ink. That printer uses a tri-color cartridge, and it has cyan (blue) magenta (red) and yellow ink. Green is blue + yellow-therefore you do have those two colors; since it will not print anything red or black you will need to replace both cartridges.
