If your prints have 1/10 in. (2.5 mm) lengthwise stripes that are the wrong color or have missing colors, you can correct the problem by cleaning the printhead. The printer automatically executes a printhead cleaning sequence when you run the Clean:Light Stripes routine from the front panel.

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

   <---- Clean Test

   Press the Clean button once again.

   A series of front panel messages indicate the condition of the printer as it progresses through a sequence of automatic cleaning routines. The printer outputs a cleaning page at the end of the cleaning sequence that you may discard as normal office waste.

   When the cleaning sequence is completed, the printer displays the following message:

   Clean:Light Stripe

   <---- Clean Test

   To confirm that the problem has been corrected, press the Test button to print a test page. Check for any missing color bars on the test page. The following illustration shows a correct test print, and an example of a test print with a missing color bar.

   If your test print looks like the first example, go on to Step 8 to end this procedure.

   If your test print looks like the second example with a missing color bar, go on to Step 6 to perform the cleaning procedure again.

   1 Black 2 Cyan 3 Magenta 4 Yellow

   If one or more of the color bars are still missing, repeat the cleaning sequence by pressing the Clean button once again. When cleaning ends, the printer outputs a cleaning page that you may discard as normal office waste.

   If the second cleaning sequence does not cure the light stripes or missing colors problem, you can press the Clean button for a third time to repeat the cleaning sequence.

   If your prints still have color stripe problems after the third cleaning sequence, turn the printer off for at least 12 hours to allow the ink to solidify. Turning the printer on again after is has completely cooled down automatically purges ink.

   If your prints still have color stripe problems, service may be required.

   Return the printer to normal operation by pressing the Exit button until the Ready message appears.
