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 159.
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 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. See
Align the printheads on page 142.
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.
The print is divided into two parts, both of which test printhead performance.
●
Part 1 (top) consists of rectangles of pure colors, one for each printhead. This part represents the
print quality that you will get from each color.
●
Part 2 (bottom) consists of small dashes, one for each nozzle on each printhead. This part
complements the first, and aims more specifically to detect how many faulty nozzles each printhead
has.
