As you can see on the photo, my printer leaves these stupid marks on the paper. Anotherproblem being paper jams time to time, this paper is one of the "went through" the printer never "got printed" issue paper. So I believe I need to clean some parts of the printer but the original guide of the printer never helps out with those. Help me get clean pages printed, and then I have some other problems.
PS: This product single handedly made us completely hate XEROX
