Have an HP CM4540 MFP that comes up with errors 59.05.50 error and 59.00.00 with no resolve. Called HP for the service manual and was transfered to a hold time of 15 minutes when the phone died.

Side note, have updated firmware, reseated fuser, reseated toner cartridges, pulled cartridges, booted without, same results.
