@NB52, Welcome to HP Support Community!

 

Step 1: Clean the scanner parts

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.

 

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 copy job to clean the scanner mechanism.

  1. Turn the printer off, disconnect the power cord, and then 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. Look for and remove any dust or debris from inside the document feeder.

  4. Spray a soft, lint-free cloth with glass cleaner, and 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. Securely close any covers and trays that you opened.

  6. Reconnect the power cord to the printer, and then try making a copy.

If the issue persists, continue to the next step.

 

Step 2: Clean the ADF rollers

If lines in copies persist when using the ADF, clean the rollers or separator pad.

  1. Turn the printer off, disconnect the power cord, and then open the ADF cover.

  2. Find any paper pick rollers and the separator pad inside the ADF. These parts have a rubber coating.

  3. Lightly dampen a clean, lint-free cloth with distilled or filtered water, squeeze any excess liquid from the cloth, and then wipe any residue off the rollers and separator pad.

  4. Leave the ADF cover open for two minutes to allow the parts to dry, and then close the cover.

  5. Reconnect the power cord to the printer, and then try making a copy.

If the issue persists, continue to the next step.

 

Step 3: Reset the printer and check the power source

Reset the printer to clear certain error states, and then check the power source to make sure the printer is getting enough power to operate the copier.

  1. With the printer turned on, disconnect the power cord from the printer, disconnect the power cord from the power source, and then wait 30 seconds.

  2. If you are using a power strip or multi-plug adapter, connect the cord directly to a wall outlet to make sure the printer is getting enough power.

  3. Reconnect the power cord to the printer, and then try making a copy

Hope this helps! Keep me posted.
