I need a schematic for a Dell 3130cn laser printer

These are next to impossible to find.  Run a google search, but --  sorry --  don't know that you will find a schematic.  Dell printers are typically made by Lexmark or Samsung and they seem to keep the innards close to the vest.

Europa303,

Thanks for that bad news  :)

Is there anyone out there with experience replacing this part?

If I order the part,  is there anyone out there who can coach me on replacing it?

I am pretty handy at fixing things, but I don't like to go in blind.
