Analyzing Test Prints
The test print shown on page 5-5 is used to evaluate and ensure that the printed image
meets the printer specifications. To make the test print:
1. From the main menu, scroll to Troubleshooting, then press the OK button.
2. Scroll to Print Quality Problems, then press the OK button.
3. Scroll to Test Prints, then press the OK button.
Note
Ensure that Edge-to-Edge printing is set to Off in the Job Defaults Menu before
starting the test print. Otherwise, the image is shifted left.
Print-Quality Defect Definitions
The Test Print (shown on page 5-5) is used to evaluate each of the print-quality
parameters. Each area of the test pattern is used for a print-quality parameter. The Test
Print analysis procedures explain each of the areas and the print-quality parameters.
Further assistance in evaluating image-quality problems is available in the
Troubleshooting Print Quality Page in the Print Quality Problems section of
the Troubleshooting menu. These pages contain detailed explanations of print-
quality and image-quality problems along with possible causes and solutions for the
problems.
