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

Grayscale

setting is not selected in your printer software.

• If you selected

Standard-Vivid

(Windows) or

Normal-Vivid

(Mac) as the quality setting in the printer

software, try selecting

Standard

(Windows) or

Normal

(Mac) instead.

• 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.
