See Remove a printhead on page 88 and Insert a printhead on page 91. 3. Align the printheads. See Align the printheads on page 148. Lines are blurred Humidity can cause ink to soak into the paper, making the lines blurred and fuzzy. Try the following: 1. Check that your environmental conditions (temperature, humidity) are suitable for high-quality printing. See Environmental specifications on page 170. 2. Check that the paper type selected in the front panel is the same as the paper type you are using. To check on the front panel, use the View loaded paper key. 3. Try changing to a heavier paper type, such as HP Heavyweight Coated Paper, HP Super Heavyweight Coated Paper, or Digital Fine Art paper. 4. If you are using glossy paper, try changing to a different type of glossy paper. 5. Select the custom print-quality options in the driver dialog (Mac OS Print dialog), and turn on the More passes option. 6. Align the printheads.
