Solution 2: Check the print settings
Solution: Check the print settings.
• Check the paper type setting to make sure it matches the type of paper loaded in
the input tray.
• Check the quality setting. Use a higher quality setting to increase the amount of
ink used for printing.
For more information, see:
• “Set the paper type for printing” on page 43
• “Change the print speed or quality” on page 44
• “Print using Maximum dpi” on page 51
• “Change copy speed or quality” on page 69
Cause: The paper type or print quality settings were set incorrectly.
If this did not solve the issue, try the next solution.
Solution 3: Clean the rollers
Solution: Clean the rollers.
Make sure you have the following materials available:
• A lint-free cloth, or any soft material that will not come apart or leave fibers.
• Distilled, filtered, or bottled water (tap water might contain contaminants that can
damage the print cartridges).
To clean the rollers
1. Turn off the product and remove the power cord.
2. Press in the tab on the left side of the rear door to release the door. Remove the
door by pulling it away from the product.
3. Dip the lint-free cloth into the purified or distilled water, and squeeze any excess
water from it.
4. Clean the rubber rollers to remove any dust or dirt buildup.
5. Replace the rear door. Gently push the door forward until it snaps into place.
6. Plug the power cord back in, and turn on the product.
7. Try to print again.
Cause: The rollers were dirty and needed to be cleaned.
