Hi guys
I have a HP Laserjet 4200 printer that the power supply had blown on and I have diagnosed the problem which includes a zener used for a reference voltage. The problem is, I don't know what rating it is to replace it and there are no markings on the PCB.
Here are the markings on the zener:
I take it B2 is the Japanese tolerance rating of 2% (1% deviance either of the normal operation voltage)?
All I need to know is the voltage details
Cheers
