• Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if

necessary.

• Align the print head.

• You may need to increase the image resolution or print a smaller size; see your software

documentation.

• If you enlarged the image in an image-editing program, you need to increase the resolution setting to

retain a high image quality. Increase the resolution by the same amount you increased the image size.

For example, if the resolution is 300 dpi (dots per inch) and you will double the image size later,

change the resolution setting to 600 dpi.

Note: Higher resolution settings result in larger file sizes, which take longer to process and print.

Consider the limitations of your computer system when selecting a resolution, and select the lowest

possible resolution that produces acceptable quality to keep file sizes manageable.

Incorrect Colors

If your printouts have incorrect colors, try these solutions:

• Make sure the Black/Grayscale or Grayscale setting is not selected in your printer software.

• Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if

necessary.

• The ink cartridges may be old or low on ink, and you may need to replace them.

• Your printed colors can never exactly match your on-screen colors. However, you can use a color

management system to get as close as possible. Try using the color management options in your

printer software.
