Random image
repetition
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.
