new ink cartridge.
• The paper may not meet paper specifications (for
example, the paper is too moist or too rough). See
“Paper Selection” on page 2.2.
• If the whole page is light, the print resolution setting is
too low. Adjust the print resolution within the printer
properties. See page 2.11.

indicate that the print cartridges need to be cleaned.
See “Cleaning the Print Cartridges” on page 6.3.
