If your copies have incorrect, uneven, smeared, or
faint colors, try these solutions:
Run a print head nozzle check to see if any of the nozzles are
clogged. Then clean the print head, if necessary.
Do not press too hard on the original when you copy from the
scanner glass.
Clean the scanner glass with a soft, dry, lint-free cloth or
use a small amount of glass cleaner on the cloth, if necessary.
Paper towels are not recommended.
Caution:
Do not spray glass cleaner directly on the
scanner glass.
Wipe any dirt or dust off of your originals.
Make sure your paper is not curled.
When vertical banding appears or the paper is smeared, clean
the paper path.
When horizontal banding appears or the top or bottom of the
paper is smeared, load paper in the correct direction and slide the
edge guides to the edges of the paper.
