These options are suggested for troubleshooting purposes and may adversely affect the final output quality
or the time necessary to generate the print job. Therefore, they should be cancelled if they do not help to
solve the problem.
A PDF file is clipped or objects are missing
In older versions of Adobe Acrobat or Adobe Reader, large PDF files could be clipped or lose some objects
when printing with the HP-GL/2 driver at high resolution. In order to avoid such problems, update your Adobe
Acrobat or Adobe Reader software to the latest version. From version 7 onwards, these problems should be
solved.
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 printhead, and whether it 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. Check that the selected paper type is the same as the paper type loaded into the printer. See View
information about the paper on page 65 .
3.
At the printer's front panel, press , then select Image-quality Maintenance > 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 ink. This part represents the print quality
that you will get from each color.
● Part 2 (bottom) consists of small dashes, one for each printhead nozzle. This part complements the
first, and aims more specifically to detect how many faulty nozzles each printhead has.
Please look carefully at the print. The names of the colors are shown above the rectangles and to the left of
the patterns of dashes.
