How to remove lines on hp scanner - easy cleaning steps

If you are experiencing lines on your scanned documents or copies when using your Hewlett Packard (HP) scanner, there are a few simple steps you can take to resolve this issue. Typically, these lines are caused by dirt, ink, white out (correction fluid), or debris on the scanner glass or Automatic Document Feeder (ADF) glass. Cleaning these areas properly should eliminate the lines and improve the quality of your scans and copies.

Step 1: Identify the Source of the Lines

Before proceeding with the cleaning process, it's important to determine whether the lines are related to the printing or scanning area. Follow these steps:

1. Print a Print Quality Check Sheet (PQCS) to check for lines in the printing area:
1. Press the ink button on your HP printer.
2. Select improve print quality.
3. Choose check print quality.
4. Press start to print the PQCS.
5. Return to the home screen by pressing home.
2. If the lines appear on the PQCS, further troubleshooting is required. If not, proceed to step

Step 2: Test with the Scanner Glass

To determine if the lines are caused by the scanner glass, follow these steps:

1. Lift the document cover of your scanner.
2. Place a single sheet of plain paper on the scanner glass.
3. Close the document cover.
4. Press the copy button on the screen.
5. Select black start to make a black and white copy.
6. If the copies still have black lines, proceed to step If not, continue to step

Step 3: Test with the ADF

If the lines do not appear when using the scanner glass, it's possible that the ADF glass is causing the issue. Follow these steps to test the ADF:

1. Remove the paper from the scanner glass.
2. Load a single sheet of plain paper into the ADF at the top of the machine.
3. Press the copy button on the touchscreen.
4. Select black start to make a black and white copy.
5. If the copies from the ADF still have black lines, proceed to step If not, your machine is working properly.

Step 4: Clean the ADF Glass

If the lines only appear when using the ADF, it's likely that there is debris on the ADF glass causing the issue. Follow these steps to clean the ADF glass properly:

1. Gather a cloth or paper towel moistened with rubbing alcohol or a window glass cleaning agent. Do not spray the liquid directly onto the machine.
2. Lift the document cover to access the small ADF glass strip on the left side.
3. Clean the white pressure bar located to the left of the white film and the thin glass strip located to the left of the flatbed glass.
4. Run your fingertip over the glass strip to check for any remaining debris. If necessary, clean the area again.
5. Ensure all areas are dry and close the document cover.
6. Make another test copy using the ADF to check if the lines have disappeared.
7. If the lines persist, repeat the cleaning process up to five times, making a test copy after each cleaning.
8. If the lines continue to appear after five cleanings, further assistance may be required. Contact HP for warranty and service options.

Step 5: Clean the Scanner Glass

If the lines appear when using the scanner glass, follow these steps to clean it:

1. Gather a cloth or paper towel lightly moistened with rubbing alcohol or a window cleaning agent. Do not spray the liquid directly onto the machine.
2. Clean the scanner glass thoroughly, including the two glass panels and the white plastic area.
3. Ensure all areas are dry before proceeding.
4. Make a test copy using the scanner glass to check if the lines have disappeared.
5. If the lines are still present, additional cleaning may be necessary. Repeat the process up to three more times, making a test copy after each cleaning.
6. If the lines persist after multiple cleanings, further assistance may be required. Contact HP for warranty and service options.
