vertical lies when printing/copying

[hp_issed]

I'm getting many vertical lines (think bar code!) when I print or copy.  I've cleaned the print heads per toubleshooting, I've cleaned the glass and ADF per troubleshooting instructions, but the lines persist.  It happens when copying and printing from a file and it does not matter if the item copied is submitted via the flatbed or the ADF.  There are NO LINES when scanning a document.

When all else fails, unplug and plug it back in.  I should ahve known that.  Thank you.
