Print quality problems associated with the environment

If the printer is operating in excessively humid or dry conditions, verify that the printing environment is within specifications. See the getting started guide for this printer for information on operating environment specifications.

Print quality problems associated with paper jams

Make sure that all paper is cleared from the paper path. See Paper jam recovery.

If the printer recently jammed, print two to three pages to clean the printer.

If the paper does not pass through the fuser, which causes image defects to appear on subsequent documents, print two to three pages to clean the printer. However, if the problem persists, see Print quality troubleshooting pages.

Over time, toner and other particles can build up inside the printer. This buildup can cause the following print quality problems:

toner that smears easily

toner specs on the page

vertical streaks or bands on the page

To correct these types of problems, clean the printer. See Cleaning the printer.
