If an image that appears at the top of the page (in solid black) repeats further down the page (in a gray field), the toner might not have been completely erased from the last job. (The repeated image might be lighter or darker than the field it appears in.)

●Change the tone (darkness) of the field that the repeated image appears in.

●Change the order in which the images are printed. For example, have the lighter image at the top of the page, and the darker image farther down the page.

●From your software program, rotate the whole page 180° to print the lighter image first.

●If the defect occurs later in a print job, turn the product off for 10 minutes, and then turn it on to restart the print job.
