driver. (See “ECONOMODE” on page 161.)
3 Open the Configure Device menu at the printer control panel. Open the Print Quality
submenu and increase the TONER DENSITY setting. (See “TONER DENSITY” on page 161.)

Specks
Specks might appear on a page after a jam has been cleared.
1 Print a few more pages to see if the problem corrects itself.
2 Clean the inside of the printer and run a manual cleaning page to clean the fuser. (See
“Cleaning the printer” on page 87 and “Running the cleaning page manually” on page 89.) If
specks occur frequently, you can set the printer to run a cleaning page automatically, if the
printer does not have an optional duplexer installed. (See “Running the cleaning page
automatically” on page 90.)
3 Try using a different type of paper.
