BEFORE USING THE MACHINE CLEANING THE LASER UNIT When the laser unit inside the machine becomes dirty, line patterns (colored lines) may form in the printed image. Identifying lines (colored lines) caused by a dirty laser unit • Colored lines always appear in the same place. (The lines are never black.) • The colored lines are parallel to the direction of paper feeding. • Colored lines appear not only on copies but also on print jobs from a computer. (The same lines appear on both copies and print jobs.) If the above problems occur, follow the steps below to clean the laser unit. Open the front cover. 1 Take out the cleaning tool for the laser unit.
