Print/Quality Plot

Introduction

Whenever a Print Quality problem appears, it is advisable to print the Print/Quality Plot to help diagnose the problem. The Print/Quality Plot will help you differentiate between possible cartridge errors and other problems such as incorrect front/panel selection, driver or RIP configuration or mechanical problems.

To achieve the best performance from the printer, advise the customer to only use genuine HP accessories and supplies, whose reliability and performance have been thoroughly tested to give trouble￿free performance and best￿quality prints.

Using the Print Quality Plot

1The size of the Print/Quality Plot is A3 and B so you must use media (roll or sheet) that is this size or larger.

2Use the same type of media that the customer was using when the Print quality problem was discovered.

3Study each of the test patterns in the order listed to determine the type of Print quality problem.

4If the customer was reporting problems of Print Quality using non/HP media and after the Print/Quality Plot test the same quality problems appear, advise the customer to use genuine HP media. Repeat the Print/Quality Plot test using genuine HP Media.

Printing the Print Quality Plot

1Before printing the plot, in Normal mode, set the Media Type and Print Quality on the front panel to the settings that you want to test.

2Load a sheet of media in portrait orientation.

3When the Ready LED lights up, press the Form Feed and Media Source keys together.

The Ready light begins to flash, and the media moves slightly forward. The carriage moves to the right side of the Printer, and the fan turns on. The Printer plots the print-quality plot and ejects the media.

4Unload the media.
