HP LaserJet Enterprise MFP, HP PageWide Enterprise MFP, HP Managed MFP – Vertical lines or streaks when copying or scanning from the ADF

Vertical lines or streaks appear on copies and/or scans when copying or scanning from the automatic document feeder (ADF). Lines or streaks might be visible on the front and/or the back side of the page.

Copies and/or scans from the flatbed glass look normal. Printed pages also look normal.

NOTE:

Some printers have different ADF scanners. For Flow models (M525c, M525cm, M527z, M575c, M575cm, M577z M575cm), or models M527, M577, M630, M680, M830, M880, E52545, and E57540, refer to the following document:

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

Cause

This multifunction printer uses a separate piece of glass (ADF glass) when making copies or scans through the ADF. HP has determined that 99% of all lines and streaks on copies made by feeding the original documents through the ADF are caused by debris on the ADF glass.

Debris can include dust, paper or toner dust, residue from sticky note adhesive, correction fluid or tape, ink, fingerprints, and more. Even the tiniest of specks can cause the light reflected off the original to be distorted, resulting in a line, streak, or smudge on copies or scans made from the ADF.

Solution

In many cases, debris is not readily visible, can be very easy to miss, and might not be removed with just a quick wipe. A soft, lint-free cloth moistened with water is usually sufficient to clean debris, but more stubborn debris might require additional steps.

Follow the steps below to isolate the issue and properly clean the appropriate area in the ADF.

In addition to the steps below, you can view the following video of how to resolve the issue when lines or streaks appear on copies when copying from the ADF.
