Print-quality problems associated with toner buildup inside the
printer

print-quality problems:
NOTE To help reduce toner buildup, always configure the media type in the tray to match the
media type that you are using. Printing on media that is a different type than the configuration
setting can cause excess toner buildup.
● Marks at even intervals on the printed side of the page
