It is usually a problem of using non OEM cartridges. Try cleaning the gold flashed contacts with alcohol.
The 59 error indicates a motor is not functioning. check all the wiring to make sure you did not leave something disconnected after you fixed the power supply.
From the HP manual.

51.X PRINTER ERROR

1. Press GO. The page containing the error will automatically be reprinted. 2. Turn the printer off and then on. 3. Reseat cables to the laser/ scanner and engine controller. 4. Replace the laser/scanner. 5. Replace the DC controller.
Try turn printer off - hold down right arrow and cancel keys...Turn printer on (keepholding keys down) - when 'perm memory init' displays, release keys. Allow printer to 'boot'..
Here are some steps you can try to resolve the issue:
Clear the jammed paper: Open tray 2 and remove any jammed paper. Open the rear door and look for and clear any paper present or obstructions in the paper path. Open rear cover. Clear Jam. Close the rear door to allow the printer to attempt to clear the jam message.
Check the fuser unit: If clearing the jammed paper doesn't resolve the issue, it's possible that the paper is stuck in the fuser unit or that the fuser exit sensor is broken. In this case, you will need to remove covers, flat bed scanner, and fuser to check for any obstructions .https://www.youtube.com/watch?v=Lz9cTnbuDbw
