Genuine Xerox 604K85850 Doc Feeder (DADF) Pickup Module Kit, pulled from a working Xerox WorkCentre 3615DN. This is the authentic OEM part (not a compatible/aftermarket reproduction) — kit includes the feed/pickup roller assembly and the separation pad assembly. Please note: the spring that normally ships with the complete kit is not included, and the rollers show light wear consistent with prior use (see photos for exact condition). Fully functional and ready to install; the spring is a cheap, easy-to-source part if you don't already have one on hand from your old unit. Compatible with Xerox WorkCentre 3615DN, 3655S, 3655X, 6655, VersaLink B400dn/B400n/B405dn, and Phaser 3610DN/3610N. Buyer to confirm exact model/part number match before purchasing.
