• If you enlarged the image size in an image-editing program, you need to increase the image resolution
setting to retain a high image quality. Increase the image resolution by the same amount you increase
the image size. For example, if the image resolution is 300 dpi (dots per inch) and you will double the
image size for printing, 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 paper type setting matches the paper you loaded.
• 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 levels may be low and you may need to refill the ink. Visually check the ink levels.
• If you printed when the ink levels were too low to be seen in the ink tank windows, refill the ink tanks to
the upper lines and run the Power Cleaning utility. Then run a nozzle check to see if print quality has
improved.
• After you print, the colors in your printout need time to set as the ink dries. During this time, the colors
may look different than you expect. To speed up drying time, do not stack your printouts on top of each
other.
