I can't believe I have been fucking with this printer for over 2 weeks. I needed to either
a) replace the transfer unit for $350 or
b) just buy a whole new (same) printer for around $550. We decided to just go with a new printer, and use this one for parts as needed since we just put a $200 part into it, plus have a full set of brand new toners for it.
Pffft.
I tried to buy a new one, but all of the places that
said they had it, in fact did not when I actually tried to purchase it. (It is a discontinued model). Then I found one on ebay for less than the cost of the transfer unit. I lost the auction.
So, Monday, ordered the replacement part, and it came today. Without installation instructions. OK, guess I'm going to wing it. Turns out, it was an insanely easy fix. Open the back, unscrew 2 screws, pull out the old TU, put in the new one, screw it in and close the back door. I just finished installing it, and so far everything seems fixed.
J.H.C that was a pain in the butt.
