HP Latex 3600 IQ Troubleshooting guide

Image quality inspection plot

The Image Quality Inspection Tool is designed to provide a guided troubleshooting process for users facing

banding issues, especially horizontal banding. The tool consists of two parts: an image to print, and a guide for

the troubleshooting process.

The image consists of 12 solid area fills of 7.62 cm x 22.86 cm (3 x 9 in). The six rectangles in the top row are

printed by a single ink each, and the six rectangles in the bottom row are secondary or tertiary colors printed

using more than one ink. Note that colors in this image may differ from the ones expected. This is a desired

behavior, since this image is not used to verify color accuracy.

This plot can be printed from the

Internal Print Server

in the

Printer

menu.

When facing banding issues, print the Image Quality Inspection Plot from the

Printer

menu: go to

Add New Job

. This will add a job to the print queue. To print it, edit the details of the job to select the

substrate and print mode you want to check. Once the plot has printed, start the troubleshooting process. See

the

Image Quality Troubleshooting Process

image at the end of this section for a summary diagram of the

troubleshooting process.

1.

Determine if the banding in the image is caused by aeroworms. Aeroworms are thin bands with higher

density than the surrounding area that appear randomly and are not continuous across the substrate.

To correct this kind of non-uniformity:

●

Increase the number of passes

●

Reduce the ink density
