A couple of potential problems.

1. The MP 7503 is not level front to back. This causes uneven developer distribution. Use a bubble level and adjust the leveler.
2. You have dust or toner on the laser shield glass. Take it out and clean it.

The biggest problem I ever had with any of them keeping the ID sensor clean. There were 2 different part numbers for the drum cleaning brush. On some one worked better than the other. And of course the one-way gears on the paper feed units.

But why they changed the transfer belt functioning? It lasts less than before!
