Diagnostic Aids designed to help Troubleshoot the HP P3015 58.04 Error
The 58.04 error is usually related to a low voltage power supply problem. So we need to check our power sources. Several years ago every thing was prone lightning strikes and power surges. These things happen a lot less now that manufactures have built boards better and electric companies have designed their system better.
HP and other manufactures want you to have these machines plugged straight into a wall outlet. Any time you call HP this is the first thing their worthless customer service people will ask you. So make sure it’s not in a strip and on the same circuit as any other large device. I’ve seen before where people plug a machine straight into a wall with other large devices and they still have issues but once out of the room the problems go away. So don’t just think because it’s plugged into a wall it must be ok. Check for other heaters like copiers, printers, coffee makers, space or floor heaters. You get the point.
Never plug these machines into UPS supplies. I can’t tell you the number of times I’ve seen damage to machines and UPS’s because these machines are plugged into them.
