Cleaning the four color print heads (black, cyan, magenta and yellow) and/or adjusting the vertical alignment may improve the print quality. To determine if the alignment needs to be set and to identify which print heads need to be cleaned, print the Print Quality Check sheet and the Alignment Check sheet.

Below are instructions for improving the following:

• Horizontal lines in text or graphics
  
  
• Blank text
  
  
• Blurred or faded text and images

• If your printed pages have a horizontal line in the text or graphics (as shown in the illustration below) or blank text, some of the nozzles may be clogged and need to be cleaned. Go to Section 1 for instructions on how to print the Print Quality Check sheet and clean the clogged print head.
  
  
  
  
  
• If your printed pages have text that become blurred or images that become faded (as shown in the illustration below), you may need to adjust the print alignment. Go to Section 2 for instructions on how to print the Alignment Check sheet and adjust the print alignment.
