Grainy Printout
If your printouts are grainy, try these solutions:
• Make sure you loaded the printable side of the paper correctly for your product.
• Select a higher print quality setting and turn off any high speed settings in your product software.
• Run a nozzle check to see if any of the print head nozzles are clogged. Then clean the print head, if
necessary.
• Align the print head using the Print Quality Adjustment setting.
• Adjust the print quality in the product software.
• You may need to increase the image resolution or print a smaller size; see your software
documentation.
Note: Images from the Internet may be low resolution and not result in a high quality printout.
• If you enlarged the image size in an image-editing program, you need to increase the image resolution
setting to retain a high image quality. Increase the image resolution by the same amount you increase
the image size. For example, if the image resolution is 300 dpi (dots per inch) and you will double the
image size for printing, change the resolution setting to 600 dpi.
Note: Higher resolution settings result in larger file sizes, which take longer to process and print.
Consider the limitations of your computer system when selecting a resolution, and select the lowest
possible resolution that produces acceptable quality to keep file sizes manageable.
