Hi
Error code 57.5 in HP 8150 means that printer fan error has occurred with the power supply fan. This issue can also be due to laser/scanner fan. Make sure both the fans are working perfectly fine. If the fans are fine, then the error is due to DC controller board.
To resolve this error turn off the printer for 4-6 hours (atleast 4 hours), this will reset the error. However, even after 4 hours you still can see the error then please check and replace the fan1 (power supply fan). Also, check for any burnt components on the dc controller board.

Hi
DC Controller board is the unit where we plug the power cord. Remove the large panel off the back of the printer. (Opposite side of the LED display) It's the metal box that runs the entire length of the printer.
After removing this housing you'll be able to see a circuit board with a fan nearby. The circuit board is the DC Controller board and fan is the Power supply fan.
You may need a multimeter to check out the DC controller board components.
Precaution-- Before doing any of this stuff please turn off your printer and unplug it from the power source as the power board stores power for a long time and can prove fatal. Make sure that the current drains out from the printer and the you disassemble it(takes approx. 10-15 minutes).

Where can I find the dc controller board? and the power supply fan as well as the laser scanner fan? Sorry to be so ignorant on the topic, just trying to get her up and running, are you in South Florida by chance?
