Horizontal line on the bottom of all scanned and copied pages, printing is OK.

HP Envy 6230
macOS 10.15 Catalina

All my scanned and copied documents have a thick black line at the bottom of the page. It's sort of green if I use colour. 

All printed pages are OK.

Using genuine HP cartridges.

I have followed the rest procedure (mains disconnected and wait 20 mins ) and also cleaned the glass. Still not fixed.

It has been working OK for several months, not heavy usage just occasional scans/copy.

Any ideas please?


Example of problem uploaded.

Welcome to the HP Support Community.


Try connecting the Printer to a different wall outlet directly.


Also, try a firmware update:
