Paper jam - Konica Minolta 5670en tray 1 think paper. I can successfully print 110lb from main tray. When I load in tray 1 , it jams exciting the fuser. Is there something I need to clean or adjust?

Place a few papers in the tray.
Open up the top, pull out the main (green handle) thingy.
In the very bottom you will see a bar with a single large round rubber wheel in the middle, and white gears on both ends of the bar.
Manually turn the right side gear toward you.
As you do this, you will see the paper lift up and as the rubber wheel turns you will see that it has a notch on the bottom side.
Turn the gear, and watch the rubber wheel until the notch on the rubber wheel is facing up and away from you (and the paper is fully engaged).
Then put the green-handle thingy back in, close the printer, and it should work.
Apparently this resets something.  I have done it a number of times - usually after a paper jam.

I believe the duplex door is in the back of the printer.

give this a try

1. Turn off the printer.
2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
3. Also open the back cover of the printer if this model has one.
4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
6. If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
7. If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
8. Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
10. see alternative if the problem is still not solved.

have you tear the paper when removing? there is a small paper left still inside the paper path. open the back side and the top part and check for small paper. I hope that will solve your problem and if think the problem still there the problem is one of the paper sensor actuator is broken or out of place.
