Switch it to another outlet and see if it resolves, if not you may have an internal printer power supply issue. Often the issue is when adding something else to the same outlet, or dependant on the system, something else to the same circuit as the printers outlet (dirty power).
FYI, you never need the numbers after the : The first number is the chain. after the comma is the subsection, after colon is just when the error happened (Its the total printed impressions on the device)
A service manual is the only place you would get access to the full list of faults, but the majority of the common ones are here

After powering on the printer it passes the self test and then displays a message stating that it is warming up. After a couple of seconds the display changes to a single line reading Error 99,008.00:4780.
I've cycled power with no change in behavior. I've also tried to look up this error code with no success. Please help with how to proceed...
