The printed output is fuzzy, blurry, or grainy, or the edges of objects in the images are jagged.
Solution
Follow these steps until the issue is resolved.
Step one: Check your paper
-
Many papers have printing and non-printing sides. Load the paper with the printing side down.
-
Use the correct paper type for the project. For everyday documents, plain paper works well. For documents with dense printing, such as high-contrast graphics or photographs, use HP Advanced paper for the best results.
-
If these steps do not help, try a different paper. Ink might not bleed as easily on heavier paper. Paper that does not accept ink well is also prone to bleeding and smearing. HP designs its inks and papers to work together.
Step two: Check the settings
-
In the program being used for printing, click File , and then click Print .
The Print window opens.
-
Make sure the appropriate product is selected, and then click Preferences or Properties .
The Preferences/Properties window opens.
-
Click the Printing Shortcuts tab.
Consider modifying some or all of the options in the Printing Shortcuts menu to increase print quality.
-
Print quality : If the quality of the printouts is not acceptable, try increasing the print quality. To print more quickly, try decreasing the print quality.
-
Paper type : If one of the options matches the paper type exactly, select it instead of Automatic .
-
Paper size : Make sure that this option matches the paper loaded in the product.
To see additional options, click the Advanced tab, and then click Advanced Features .
The Advanced Features window opens. Consider changing the following option:
Ink volume : Adjust the amount of ink that prints on a page. For lighter images (less ink), drag the slider to the left. For darker images (more ink), drag the slider to the right. The lighter the ink volume, the more quickly the printout dries.
Step three: Check image resolution
Make sure that the image file has enough resolution for the size of the printed picture. Although many photo applications can enlarge an image or part of an image to any size, eventually the individual pixels become visible and the whole image looks blurry.
Here are some general guidelines for image file resolutions:
-
94 pixels per cm (240 pixels per inch) for images to print on smaller format photo paper, such as 10 x 15 cm (4 x 6 inch)
-
117 pixels per cm (300 pixels per inch) or higher for larger format photo papers
-
Lower resolutions might produce acceptable images when printed on rough-textured paper
Step four: Align the cartridges
If the previous steps have not improved the appearance of the printout, align the cartridges. See the user guide for alignment instructions.
