When faced with a Print Quality problem, perform the following actions in order to resolve the problem: Troubleshooting 1. Printer Configuration: ● Check that the paper type loaded corresponds to the paper type selected in the front panel and in the software. You can check the paper type selected by pressing the View information key on the Front Panel. ● Make sure that the correct Print Quality settings are used for different types of print content. See Print-quality troubleshooting actions on page 6 for further information. ● Dry time should be set to “Optimal”. 2. Perform Printhead recovery (Main Menu/Image Quality Maintenance/Clean Printheads). 3. Paper:
● Select the correct paper type through the front panel when loading it. ● Make sure that HP or HP-approved paper is being used. 4. Perform the Printhead Alignment (Main Menu/Image Quality Maintenance/Align Printheads), using the same paper type with which you were experiencing unacceptable image quality, if feasible (some paper types are not suitable for Printhead Alignment). 5. Check whether the latest version of the firmware is installed. If not, install the latest firmware revision. The Service Image Quality Diagnostic Print What is the Service Image Quality Diagnostic Print?
The printer contains an internal Image Quality Test which helps you to diagnose the possible source of any image quality defects. The Service IQ Diagnostic Print is available in the following options: 1. Image Quality Service Best Plot. This plot helps you to diagnose in more detail the possible source of any image quality defects. It is accessible through the Service Utility Menu. The Image Quality Service Best Plot uses the Best Print Mode and is divided in to three parts as follows: ● Diagnostic Part 1: Printhead Reliability Test. The purpose of this test is to identify which Printhead is faulty. ● Diagnostic Part 2: Printhead Alignment Test.
This test is designed to check any color-to-color and bi-directional misalignment the printer may have. ● Diagnostic Part 3: Printheads and Paper Advance test. This test is designed to check whether the Printheads and the Media Advance Mechanism are working correctly. 2. Image Quality Service Normal Plot. This plot is the same as the Image Quality Service Best Plot but uses the Normal Print Mode. 3. Advanced Diagnostic Plot. These tests provide more information of the IQ defects that we could find in the Image Quality Service plot. For more information, see The Advanced Diagnostic Prints on page 12 .
