To correct this kind of problem:
1. Reseat the printheads by removing them and then reinserting them. See Remove a printhead

If your lines are broken in the following way:
1. Check that you are using appropriate print-quality settings. See Printing on page 49 .
2. Reseat the printheads by removing them and then reinserting them. See Remove a printhead
on page 117 and Insert a printhead on page 120 .
3. Align the printheads. See Align the printheads on page 168 .
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 186 .
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 information key .
3. Try changing to a heavier paper type, such as HP Heavyweight Coated Paper or HP Super
Heavyweight Plus Matte Paper.
4. Select a paper type that is slightly thinner than the paper you have loaded; this will persuade 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.
