HP LJ 9000 Printer Error 58.4.

[coodbgood]

Can anyone please tell me what Printer Error 58.4 indicates on an HP LJ 9000? The printer was completely dead until I replaced the LV Power Supply. After warm up, the display came up with Printer Error 58.4. The unit also asks for a PIN to access the Service Menu. I don't think the unit has ever been serviced before. Is there a default PIN set up in the printer initially? Thank you in advance for any help you can provide.

The PIN for the 9000 is 00900001.

Thanks very much Brian for the PIN for the Service Menu. I bought a service manual to get the error codes and the codes for error 58.x aren't identified with the "x" number. Everything for error 58 is listed as 58.x.
