HP LaserJet Enterprise MFP, HP LaserJet Managed MFP - Lines or streaks when copying or scanning from the automatic document feeder (ADF)

Follow these steps to determine if the issue occurs when using the ADF glass or the flatbed scanner glass.

1. Make a blank copy from the ADF and mark it "ADF."

2. Make a blank copy from the flatbed scanner glass and mark it "flatbed."

3. Look at the blank copies for the presence of lines or streaks, and then proceed with one of the following actions based on your findings:

   • If the issue is visible on the copy marked "ADF," proceed to Step two: Clean the ADF glass and white strip on the underside of the scanner lid.

   • If the issue is visible only on the copy marked "flatbed," use a soft, lint-free cloth moistened with water to clean the flatbed glass and lid backing.

     Note:

     If needed, lens cleaner or nonabrasive glass cleaner can be applied to the cloth before cleaning the glass. Spray only onto the cloth and not directly onto the glass or printer. Do not spray water or glass cleaner on the glass as it can seep under it and possibly damage the printer.

     Do not use abrasives, acetone, benzene, ethyl alcohol, or carbon tetrachloride on the glass; these can damage it and/or leave residue on the glass resulting in degraded copy/scan quality.

Follow these steps to clean the ADF glass and white strip on the underside of the scanner lid.

1. Open the scanner lid and locate the one-inch strip of glass to the left of the main scanner flatbed glass.

2. Use a soft, lint-free cloth moistened with water to clean the ADF glass. Some models use an upper ADF glass similar to the lower one. In this case, perform this cleaning step for both the lower and upper ADF glass.

   Note:

   If needed, lens cleaner or nonabrasive glass cleaner can be applied to the cloth before cleaning the glass. Spray only onto the cloth and not directly onto the glass or device. Do not spray water or glass cleaner on the glass as it can seep under it and possibly damage the printer.

   Do not use abrasives, acetone, benzene, ethyl alcohol, or carbon tetrachloride on the glass; these can damage it and/or leave residue on the glass resulting in degraded copy/scan quality.

3. On the underside of the scanner lid above the strip of ADF glass, use a soft, lint-free cloth moistened with water to clean the upper white strip and metal strip (if applicable). In some cases, this is a glass strip similar to the ADF glass.

   Note:

   Do not scrub or use paper-based wipes as this can scratch the surface.

4. If the white strip does not come clean, try again using isopropyl alcohol, and then wipe the surface thoroughly with a damp cloth to remove any residual alcohol.

5. Dry the ADF glass and upper strip with a soft, dry cloth to prevent spotting and then try again to copy or scan.

   If the issue persists, continue to Step three: Isolate the location of the debris on the ADF glass.

Follow these steps to isolate the location of the debris on the ADF glass.

1. Place a blank sheet of paper in the ADF and mark an "X" in the lower right corner (as shown below).

   Load a blank page with an "X" marked in the lower right corner into the ADF

   

2. Press the Start button to make a copy of the blank page.

3. Place the copied paper face-up on the flatbed glass with the "X" located in the lower right corner (as shown below).

   Note:

   Make sure the upper left corner of the copy is aligned with the upper left corner of the flatbed glass.

   Place the copied page face-up on the scanner glass with the "X" in the lower right corner

   

4. Follow the line or streak on the paper to the area on the ADF glass that is causing the issue.

5. Use a fingernail to loosen any stubborn debris.

   Note:

   Use only a fingernail. Other objects can scratch the ADF glass.

6. Clean this specific area on the ADF glass again and then dry it with a soft, lint-free cloth.

7. Try again to copy or scan.

To clean the duplex scanner glass, remove and clean the Side 2 Background Selector, and then clean the Scan Module Glass.

In addition to the steps below, you can view the following video of how to clean the Side 2 Background Selector.

   4. Use a soft, lint-free cloth moistened with water to wipe clean the white and black areas on the backside reflector.

      Note:

      If the white and black areas do not come clean, try again using isopropyl alcohol, and then wipe the surface thoroughly with a damp cloth to remove any residual alcohol. Dry the area with a soft, dry cloth to prevent spotting.

3. With the Background Selector removed from the ADF, clean the inside of the scan module.

   1. In the back of the area where the Background Selector was removed, locate the Side 2 Scan Module glass under the top area.

      Note:

      The glass surface of the Side 2 Scan module sits horizontally flat and might not be easily viewable.

   2. Use a soft, lint-free cloth moistened with water and apply pressure upwards behind the rollers to clean the Side 2 Scan Module Glass, making sure that the entire width of the glass is cleaned from left to right.

      Note:

      If needed, lens cleaner or non-abrasive glass cleaner can be applied to the cloth before cleaning the glass. Spray only onto the cloth and not directly onto the glass or device. Do not spray water or glass cleaner on the glass as it can seep under it and possibly damage the printer.

      Do not use abrasives, acetone, benzene, ethyl alcohol, or carbon tetrachloride on the glass; these can damage it and/or leave residue on the glass resulting in degraded copy/scan quality.

      Clean the Side 2 Scan Module

      

   3. Dry the scan module gently with a soft, lint-free cloth.

4. Reinstall the Side 2 Background Selector.

5. Close the ADF lid and then try again to copy or scan.
