Copies streaked with black

[Velmablack]

My printer is printing and scanning with no issues, but when I copy something, it comes out covered with vertical black lines over the content.  How can I fix this?

Hello velmablack,

Welcome to the HP Support Forum!

I see from your message that you getting vertical streaks for copy, but not for print/scan.  This issue is likely resolved by cleaning the scanner glass (i.e. small amout of dirt on the glass can create the vertical streaks).  I hope this helps!

Hi Velmablack,

This has occurred on my printer-scanner-copier before.

Sometimes there is a speck of dirt or a spot on the glass that needs cleaned off.  When that paper goes through the automatic document feeder the "speck" turns into a line as the paper goes across.  You may want to clean the glass.  See if this helps.

The soltution for me was to clean the scanner glass.  The auto scanner moves the paper by non moving laser head, so that any small speck or flaw in the strip of glass over the non moving laser head area results in a vertical printed line.  I found that there was a miniscle speck that was not removed by simple wiping and needed scrubing with alchohol to remove it.  When the laser head moves under the flat bed glass, specks show up just as that, a speck.  So is is important to carefully inspect the small strip of glass over the non-moving area of the laser head and clean even the smallest speck of dust or smudge.

I purchased this printer last summer and numerous time I have had copies streaked with black.  I have already

cleaned the glass and turned the printer off.

Thank you
