Print Quality Problems
You see banding (light lines).
The print head nozzles may need 
cleaning; see page 19 for instructions.
Make sure the Media Type setting 
matches the paper you loaded. See 
page 17 for guidelines.
Make sure the printable side of the 
paper is face up. It is usually whiter or 
shinier.
The ink cartridges may be old or low 
on ink. To replace an ink cartridge, 
see page 21. 
Try using Automatic mode. See 
page 7 (Windows) or page 11 
(Macintosh) for instructions.
Run the Print Head Alignment 
utility. See page 24 for instructions.
Your printout is blurry or smeared.
Make sure your paper isn’t damp, 
curled, or loaded face down (the 
printable side should be face up). If 
it’s damp or curled, reload a new 
stack of paper.
Use a support sheet with special 
paper or try loading your paper 
one sheet at a time.
Make sure your paper meets the 
specifications listed in your electronic 
Reference Guide.
Run the Print Head Alignment 
utility. See page 24 for instructions.
Remove each sheet from the output 
tray as soon as it’s finished printing, 
especially if you’re using 
transparencies.
