Lines are discontinuous
If your lines are broken in the following way:
1. Check that you are using appropriate print-quality settings. See Printing on page 47.
2. Reseat the printheads by removing them and then reinserting them. See Remove a printhead on page 102
and Insert a printhead on page 104.
3. Align the printheads. See Align the printheads on page 149.
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 specications on page 163.
2. Check that the paper type selected in the front panel is the same as the paper type you are using. See View
information about the paper on page 32.
3. Select the custom print-quality options, then select Best and Maximum detail (if available). See High-quality
printing on page 56.
4. Try changing to a heavier paper type, such as HP Heavyweight Coated Paper or HP Super Heavyweight Plus
Matte Paper.
5. Select a paper type that is slightly thinner than the paper you have loaded; this will cause the printer to use
less ink. Here are some example paper types in ascending order of thickness: Plain Paper, Coated Paper,
Heavyweight Coated Paper, Super Heavyweight Plus Matte Paper.
6. If you are using glossy paper, try changing to a dierent type of glossy paper.
7. Align the printheads. See Align the printheads on page 149.
