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 .
Print quality problems associated with toner buildup inside
the printer
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

● vertical streaks or bands on the page
To correct these types of problems, clean the printer. See Cleaning the printer .
