Question about HP Media Center m7250n (ED842AA) PC Desktop
I am facing this problem in this printer.Pls help me to solve this.what may be problem?.How can solve?
The 57.03 error relates to a problem with the fans, in particular, the right fan. Try reseating the connector for the fan in the DC controller board. (DO THIS WITH POWER DISCONNECTED!!!) If that does not fix the problem, it is most likely the DC controller board failed, which will have to be replaced.
Hope this helps you out,

To continue turn off then on
A main motor (M1) error has occurred. Motor
operation is verified during device power-up.
1. Turn the device off and then on.
2. Verify that nothing is hindering the main
motor. If necessary, remove all paper
trays and the print cartridge, and then
turn on the device and listen for motor
3. Verify that the main motor is connected
to connector J407 on the ECU. (See
Figure 6-9 ECU wiring on page 195.)
You might have to remove the main
cooling fan to see this connection.
4. If the message persists, replace the
