End user installed new imaging unit.
Printer would no longer recognize unit as being installed.
Called me
I tried old unit , same result
I tried new,new unit, same result
Can anybody please tell me what part is responsible for telling the
printer is has the image unit installed?
Checked all visible sensors,flags,top cover, and contacts.
Xerox has parts diagrams for the 6250 color printer, but cant seem
to find a complete manual
I 've purchased from several internet manual site's, only to find the
wrong one,or incomplete

A little help please, will trade HP and Lexmark info, for Xerox info
if needed.
Thanks
