Print Quality Problems

Print Quality Problems
You see banding (light lines).
Your printout is blurry or smeared.
Make sure your paper isn’t damp or curled, or loaded face-down (the printable side should be face-up). If it’s damp or curled, reload a new stack of paper.
When printing on special paper, check the instructions in the paper package. You may need to use an included support sheet or load your paper one sheet at a time.
Windows: From the Maintenance tab in the Printing Properties or Preferences window, click Printer and Option Information, then select Thick paper and envelopes.
Mac OS X: From the Print window, choose Extension Settings in the pop-up menu, then select Thick paper and envelopes.
Make sure you disable the thick paper and envelopes option before printing on other types of paper, or print quality may be reduced.
Your printout is grainy.
Your printout is faint or has gaps in the image.
Make sure your paper isn’t damaged, old, dirty, or loaded face-down. If it is, reload a new stack of paper with the printable side up; it is usually whiter or shinier.
You see wrong or missing colors.
Make sure the Ink setting is set to Color for color images or black-and-white photos. Also make sure your software is set for color printing.
Try turning off PhotoEnhance. Also check if you’re using a special effect that alters image colors, like Sepia.
Try changing the Gamma setting in the Advanced window; see Customizing Windows Print Settings or Customizing Mac OS X Print Settings for information about accessing Advanced settings.
Your printed colors can never exactly match your on-screen colors. However, you can use a color management system to get as close as possible. You can also use your printer’s color management features.
If you are printing without a computer, check your printer’s control panel settings to make sure the Filter setting is not set to Sepia or B&W and that the image adjustment settings are set to Standard (see your Printer Basics manual).
