Problem Solution Light or faded print AaBbCc AaBbCc AaBbCc AaBbCc AaBbCc If a vertical white streak or faded area appears on the page: • The toner supply is low. You may be able to temporarily extend the toner cartridge life. See "Redistributing Toner" on page 6.4. If this does not improve the print quality, install a new toner cartridge. • The paper may not meet paper specifications (for example, the paper is too moist or too rough). See "Paper Specifications" on page G.3. • If the entire page is light, the print resolution setting is too light or Toner Save Mode is on. Adjust the print resolution and Toner Save Mode in the printer properties. See page 5.25 and page 5.9 respectively. • A combination of faded or smeared defects may indicate that the toner cartridge needs cleaning.
