Before attempting the image quality diagnostic procedures contained in this section, you should first check that
the printer is correctly configured to print what you want. Many problems concerned with image quality can be
solved by correcting the way the printer is configured.

1. To achieve the best performance from your printer, only use genuine HP accessories and supplies, whose

reliability and performance have been thoroughly tested to give trouble-free performance and best-quality
prints. For details of HP media, see

Paper Types

2. Make sure that the Type of paper selected in the front panel is the same type of paper loaded into the printer.

To check this go to the Roll or Sheet menu in the front panel and press Enter.

3. To ensure the maximum print quality use HP certified media only. For details of HP media see

Physical

Characteristics of Paper Types

. You can also look at the web page

for the

most up-to-date information.

4. Make sure that the Print quality (Fast, Normal, Best) used for your printer is correct. This is set in the Print

Setup dialog box of the printer driver or in the front panel from the Set-up menu. The printer driver setting
overrides the front panel setting.

5. Select Best print mode for maximum print quality.

6. For Non-HP drivers, set front panel media settings to match the media type loaded in the printer. The

documentation that came with your software should provide information about media type/print quality
settings.

7. If your image quality problem is color accuracy related, go to
