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.
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.
