HP LaserJet Enterprise P3015 Series Tray 3 Not being detected after ECU Replacement

HP Recommended
HP LaserJet Enterprise P3015
Microsoft Windows 10 (64-bit)

Replaced the ECU in our P3015 and everything is working as it should except when we add our optional Tray 3. The printer does not detect the tray at all and i fear that i missed a cable for the power while doing the ECU. Tried to Find a Diagram for the ECU board to determin what connector actually supplies power to the Connector on the bottom of the printer with no luck what so ever. I am going to have to open the machine back up and check, but would really love to know what connector actually supplies the power.

 

Thank you in advance!

Hi @JamieOj,

 

I don't have a ECU diagram to give you, but I reckon that you will have to open the printer again and check if every connector is connected properly.  Sometimes they either not connected fully or are totally unplugged (forgotten behind the ECU or other parts). Also take a careful look at the two connectors, one on the tray-3 and one at the bottom of the P3015 body that connects to the tray-3 for any obvious damage there.

In the end i had to just open up the printer again and found that on the left hand side of the ECU board starting from the bottom and going up, the first purple long connector is what i was looking for.  This connector had to be pushed in more to make the secure connection and sits farther in than the other connectors.  Testded and verified that Tray 3 is now working.
