White spots on the print You may notice white spots on the print. This is probably due to paper fibers, dust, or loose coating material. To avoid this problem: 1. Try cleaning the paper manually with a brush before printing, to remove any loose fibers or particles. 2. Always keep the cover of your printer closed, and avoid actions that may introduce dust into the printer, such as handling or cutting paper on the printer cover. 3. Protect your paper rolls and sheets by storing them in bags or boxes. Colors are inaccurate If the colors of your print do not match your expectations, try the following: 1.

Check that you are using appropriate print-quality settings (see Printing on page 75). If you have selected the Speed or Fast options, you may not get the most accurate colors. If you change the print-quality settings, you may wish to reprint your job at this point in case the problem has been solved. 5. If you are using Application Color Management, check that the color profile you are using corresponds to the selected paper type and print-quality settings. If you have doubts about which color settings to use, see Color management on page 131. 6. If a grayscale image shows a color cast in some of the gray shadows, click Color > Grayscale in the driver.
