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 190
.
2.
Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. 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 Plus Matte Paper or Digital Fine Art 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, Fine Art Paper, Super Heavyweight Plus Matte
Paper, Thick Fine Art Paper (>250 g/m²).
5.
If you are using glossy paper, try changing to a different type of glossy paper.
6.
Select the custom print-quality options in the driver dialog (Mac OS Print dialog), and turn on the
More passes option.
7.
Align the printheads. See
Align the printheads on page 172
The Image Diagnostics Print
The Image Diagnostics Print consists of patterns designed to highlight printhead reliability problems. It
helps you to check the performance of the printheads that are currently installed in your printer, and
whether any printhead suffers from clogging or other problems.
To print the Image Diagnostics Print:
1.
Use the same paper type that you were using when you detected a problem.
2.
Use the
View loaded paper
key on the front panel to check that the selected paper type is the same
as the paper type loaded into the printer.
3.
At the printer's front panel, select the Image Quality Maintenance menu icon
, then Print
diagnostic image.
It takes about two minutes to print the Image Diagnostics Print.
