To resolve the issue, clean the ADF glass and white plastic strip, and then make a test copy.
Step one: Clean the ADF glass and white plastic strips
If the ADF glass or white strip has fingerprints, smudges, lint, dust, or other debris, copies and scans through the ADF might contain vertical white or black lines. Follow these steps to clean the ADF glass and white plastic strips.
  1. Gather the following materials:
    • Several clean, soft, lint-free cloths
    • Mild glass cleaner
      Use only glass cleaner to clean the scanner glass. Do not use cleaners that contain abrasives, acetone, benzene, or carbon tetrachloride. These substances can damage the printer. Avoid isopropyl alcohol (rubbing alcohol) because it can leave streaks on the glass.
  2. Press the Power button to turn off the printer, and then disconnect the power cord from the rear of the printer.
  3. Lift the scanner lid.

  4. Spray a clean, soft, lint-free cloth with mild glass cleaner.
    To protect the scanner, do not spray the glass cleaner directly on the glass.
  5. Clean and thoroughly dry the small strip of glass to the left of the scanner glass, and then clean and dry the white plastic strip on the left underside of the scanner lid.

Step two: Make a test copy from the ADF
  1. Find an unused, plain white piece of paper.
  2. Place the plain white piece of paper into the document feeder tray. Adjust the width guides to fit.

    • If the copy does not contain any blemishes or spots, you can stop troubleshooting.
    • If the copy does contain blemishes or spots, repeat these steps to clean the ADF glass and plastic strip.
    • If the copy contains vertical bands, lines, or streaks, there might be dust inside the printer, poor internal connections, or the printer might be damaged. Continue to the next step.
