Hi!!
The problem of this printer is can not be turned on .I checked and found there is a diode shorted on the control board,its p/n is :
S4
66A
May I know the datasheets of this diode or any replacement/equivalent for this type of diode?

Many thanks!!

Hi:
From long experience with HP I have found that kind of information
is not going to be provided. Short of having a junker to rob for parts you are probably out of luck. For a lot of the small units now no parts are available.

Did you lift one side of the diode and check it with a meter?

These are switching power supplies and are impossible to repair without very special equipment.
