Use a paper roll that has a black core. You cannot use a paper roll with a non-black paper tube or a paper roll where the trailing edge of the paper is glued to the paper tube. Do not use it, because doing so will cause a paper jam when the paper runs out as well as cause other problems.
If humidity is high, and the paper roll has expanded due to moisture, be sure to cut off with scissors approximately 1000 mm (40 inches) before making copies or printing. Then load the paper roll, and select [Cut] on the screen.
Depending on the paper being used, a horizontal misregistration may occur. If this happens, contact your service representative.
