Hi @Rodneyrosado2,

I'd like to help!

Does this happen even when you make a copy ?

Please try the below suggestions-

Fingerprints, smudges, dust, or debris on the scanner glass, under the scanner lid, or in the document feed slot can cause lines and color bands. Clean these parts with a soft, lint-free cloth sprayed with glass cleaner.

Printer with flatbed scanner glass and lid

Printer with a document scan feeder

Printers with a flatbed scanner glass and lid

Clean the scanner glass and underside of the scanner lid with a soft, lint-free cloth sprayed with glass cleaner.

1. Turn the printer off, then disconnect the power cord.

2. Lift the scanner lid.

3. Spray a soft, lint-free cloth with glass cleaner, then wipe the scanner glass, glass strip (if present), the white backing under the scanner lid, and the white strip under the lid (if present) until clean, dry, and streak-free.

      CAUTION: 

   To protect the interior printer parts, do not spray the cleaner directly on the glass or on the underside of the lid.

   Figure : Clean the scanner glass and under the lid, and any glass or white strips (if present)

   1. White scanner lid backing

   2. White ADF scanner lid strip (if present)

   3. Glass ADF scanner strip (if present)

   4. Main scanner glass

4. Reconnect the power cord, turn on the printer, then close the scanner lid completely.

5. Load the original document or photo, then try to scan. Make sure the original document or photo is in good condition and free of tears, creases, folds, staples, or tape.

   If the issue persists, continue to the next step.

Printers with a document scan feeder

Clean the plastic and glass strips inside the document feeder with a soft, lint-free cloth sprayed with glass cleaner.

NOTE: 

Some printers ship with a document feeder cleaning cloth. If you have the cloth, load it into the document feeder and start a scan job to clean the scanner mechanism.

1. Turn the printer off, disconnect the power cord, and remove the battery if your printer has one.

2. Depending on your printer model, open any top cover, document feeder tray, and scan document feeder cover.

3. Remove any debris such as bits of paper or paper clips from inside the document feeder.

4. Spray a soft, lint-free cloth with glass cleaner, then wipe the scanner glass and the white strip on the underside of the document feeder until clean, dry, and streak-free.

      CAUTION: 

   To protect the interior printer parts, do not spray the cleaner directly on or into the printer.

5. Completely close any covers and trays that you opened.

6. Reconnect the power cord, reinstall the battery if necessary, then turn on the printer.

7. Load the original document or photo. Make sure the original document or photo is in good condition and free of tears, creases, folds, staples, or tape.

8. To avoid skewing, adjust the guides on the document feeder to remove any gaps next to the edges of the paper and the guide. The paper stack should slide easily into tray and not bind against the guides.

   Try to scan. If the issue persists, continue to the next step.

Reset the printer

Resetting the printer can force some types of scanners to calibrate, which might fix the problem.

1. Remove any items from the scanner glass and automatic document feeder (ADF), then close the scanner lid.

2. With the printer turned on, disconnect the power cord from the printer and from the wall outlet or power strip.

3. Wait at least 60 seconds.

4. Plug the power cord back into a wall outlet.

   NOTE: 

   HP recommends connecting the printer power cord directly to a wall outlet.

5. Reconnect the power cord to the printer.

6. If you have an HP DeskJet 3700 series printer, calibrate the scanner after resetting the printer.

7. Load the original document or photo, then try to scan.
