This issue is typically caused by incorrect printer settings. With grainy images, the most common resolution to this problem is to increase the Dots-Per-Inch (DPI) setting of the printer. Pictures that print without color generally require changing the color mode settings in print properties, or replacing the color ink cartridge installed in the printer.
This can also occur by printing a low-resolution digital image (such as 640x480) as an 8x10 inch print. Reduce the print size of lower resolution images to improve the print quality.
- Changing the DPI of an image using photo editing software will have no effect on the printed quality of the picture.
- Contact the manufacturer of the printer for further assistance.
