Brother HL-2230 Laser Printer Creases & Creasing on Manual Duplex Printing

I have a Brother HL-2230 Laser Printer and I just started printing hundreds of duplex prints for a school project. In case you don’t know, duplex printing is when you’re trying to print on the front and back of one single page. Unfortunately, the pages in my Brother HL-2230 kept getting creases during the printing of the second side and it was ruining my print outs. Well, I finally figured out the solution for preventing the creases on the second side.
