I'm using roll paper to print my photography but for some reason the paper is coming out marked. It is always in the same place and running in the same direction as the print head. The mark is about 2" inside of the paper. It is coming out with the marked part first indicating that it is not when the paper is being cut? Unless it is be is being marked on when the previous page was printed / cut. I am new to printing and have no idea what this can be? Any help is very welcome. I have googled it and checked the manual but to no avail.
