HP Designjet Z3100 Photo Printer Series - Users Guide

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.

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.

Please look carefully at the print. The names of the colors are shown above the rectangles and in the

center of the patterns of dashes.
