hp clj9500 59.A0 Error – HP Enterprise Business Community

Posted by jpluimers on 2016/01/08

If my HP CLJ 9500 ever again gets the 59.A0 PRINTER ERROR the below helps by [Wayback/Archive] Seif.

For me the first half of the first step worked (remove the toner bottle, reseat the cleaning blade, put back the toner bottle).

If that fails, here are all of them:

  1. Reseat the cleaning blade, and ITB.
  2. Defeat the Toner Bottle flag and run without a Cleaning Blade to determine if the blade is causing the motor to stop or not.
  3. Remove ITB and verify that it rotates freely.
  4. Remove back and right side skins, and cover over the ITB motor – verify that the ITB drive assembly rotates freely. Verify that the ITB motor pinion is located correctly on the motor shaft (aligned with the second gear in the train).
  5. Remove the Image Transfer Roller, and pull the white gear off of the end of it. Verify that the drive train for this roller moves freely by removing the ITB, the HVPS, and turning the registration motor by hand while watching the gear train to the T2 roller for binding.
  6. Verify signal connectors between the ITB motor and DC Controller, particularly the FFC between the Process-driver and the DC controller.
  7. Check connector on lower right hand side (nearest 2 capacitors) for a solid connection. This connector goes to the HVPS.
  8. Replace the motor assembly.
  9. Replace the DC Controller.
  10. Replace the Image Drum Drive PCB Board
