I have a black line down the middle of page when making copies

Hi,

Thanks for using the HP Forums.

The issueis probably caused by a small spec on the ADF scanner glass, the thin glass just to the left of the main bed

The same sensor is used for both the flatbed scan and the automatic document feeder (ADF), the difference is where the sensor is moved to for scanning.  When scanning from the flatbed the sensor moves across the bed, a spot in this area will result in a spot on the page.  When using the ADF the sensor is moved to the thin glass to the left of the main bed, and the paper is moved past the sensor by the ADF.  A spot in the wrong place here will result in a lind down the length of the long side of the page.  Clean this areas as shown below.

Figure : Locate any debris on the ADF scanner glass strip

If the initial cleaning does not resolve the issue it may help to shine a bright flashlight nearly parallel to the glass.  For a line on the left side of the printed page the spot will be toward the front of the printer, if the line is on the right of the paper it will correspond to a spec toward the rear of the printer.

Hope that help!

That suggestion worked like a charm!  I'm sad for all those months that i didn't use the auto-feed feature because of the line down the middle of the pages. Thank you!
