Clean the printer's internal paper path surfaces if you note the following:

• Your prints have stray ink marks on the front or the back.

• The media is wrapping around the large black roller inside the exit cover.

  ---

  Caution: Always use clean sheets of paper to clean the paper path. Do not reuse cleaning sheets. High-grade, heavier papers, such as 120 g/m2 (32 lb.) bond, work best.

  Do not attempt duplex (two-sided) printing on any type of media. Ink already present on the media offsets onto the internal paper path, requiring you to perform cleaning procedures.

1. Load at least 10 sheets of clean, high-grade paper into the printer. If your printer is configured with just the upper media tray, load that tray. If you have installed the Lower Paper Tray Assembly, you can load either the upper tray or the lower tray. If you use the lower paper tray, make sure that the printer's default has been reset so that the printer will feed paper that it needs for its cleaning procedures from the lower paper tray only. Refer to Selecting the Cleaning Page source for instructions.

2. When the printer is on and the Ready message or the printer's name appears in the front panel, press the Clean button. The printer displays the first selection in the menu:
   Clean:Light Stripes

   <---- Clean Test

   Press the left arrow (<---) button until the following front panel message appears:

   Clean:Ink Smears

   <---- Clean Test

   Press the Clean button. The printer displays the following message:

   Warming Up

   Cancel

   After a short delay during the warm-up period, the printer begins an automatic sequence of feeding 10 clean sheets of paper from the media tray selected as the cleaning page source. A front panel message indicates the number of sheets remaining to be fed. For example:

   Cleaning:Using 10 Sheets

   When the cleaning sequence is complete, inspect the last sheet of paper fed through the printer. If it is not clean, repeat the cleaning sequence by pressing the Clean button once again.

   Return the printer to normal operation by pressing the Exit button.
