Dell Laser P1500 Error Codes

I am looking for a list of secondary error codes that a P1500 can give.  Specifically the nature of the code my P1500 is giving me but I'm sure others out there would appreciate the list as well.

 

When turning on my P1500 it starts it's normal system diagnosis as you can see the indicator lights systematically checking it's self.  The problem seems to occur right before it normally spins up for a brief second before finalizing its test. 

 

The printers first error code show all lights flashing:

 

Flashing Ready|Data

Flashing Toner Low

Flashing Load|Remove Paper

Flashing Paper Jam

Flashing Error

Flashing Press Continue

 

By pressing continue twice to get to second error codes the lights show:

 

Flashing Ready|Data

Off      Toner Low

Flashing Load|Remove Paper

Flashing Paper Jam

Flashing Error

Flashing Press Continue

 

Pressing continue twice more shows:

 

Off      Ready|Data

Flashing Toner Low

Off      Load|Remove Paper

Off      Paper Jam

Off      Error

Off      Press Continue

 

Pressing continue twice more brings back to all lights flashing

The computers ( I have tired more than one with diff USB and A parallel cables) do not see the printer as being attached.  My toner is half full. I checked the internal power board in base of printer and the fuse is good.  The error should not have anything to do with being connected to a computer or not because when it was working and not connect to a computer it would not blink all the indicator lights (If I remember correctly, just the Press Continue light would be lite). 

 

Information I have found so far:

1. http://support.dell.com/support/edocs/systems/p1500/en/index.htm#online_documentation  

o    Under PDF Documents Owner's Manual (English) (.pdf) (1.33 MB) shows very little about the indicator lights.

 o    Under HTML Documents User's Guide  shows more information about the indicator lights but mentions nothing about the secondary error codes.

1. The Lexmark E321/E323/E220 are very close cousins to the P1500 and on Lexmark’s website the manuals have more info on secondary codes but nothing that matches my error.

•  Lexmark E220 User's Reference Starts on Page 45  Secondary codes start on Page 47
•  Lexmark E321, E323 User's Reference Starts on Page 47  Secondary codes start on Page 49

 

 Information I am guessing could be the problem:

1. The fuser has gone out (need to know how to check) Why else would they sell the fuser if it didn't go out regularly Part Number:  56P1053
2. Clutch Assembly  I'm not sure of the accuracy of the info on this page.
