Good afternoon fellow believers,
Came across one that was making me pull out what's left of my hair!! An MP 7502 getting J019 jams at the duplex entrance guide. The paper was actually leaving the fuser and hitting the duplex frame, rather than going past the sensor and into the duplex unit itself.
I noticed the guide plates that shift to the left when you close the fuser drawer weren't going far enough to the left, and the pressure plate was actually moving freely on the shaft. I replaced it with the updated version that has 3 roll pin locations, instead on the single one, and the issue is resolved. Here's a pic of the broken part, to give you an idea what to look for if you start getting those same jams.

Good luck gang....
