On an Officejet Pro L7580 I'm getting narrow vertical black lines on the image when I print photos. These do not appear on the sheet when printing documents or graphics or scanned images, only within the photo itself when it is printed. Printheads have been changed, the unit unplugged ('reset') alignment carried out, etc. etc.
The original jpg files look clean, ie. no vertical lines can be seen on the original image when viewed on the monitor prior to printing.

I would suggest doing a hard reset with the printer first.
Unplug the power cord from the printer and wall
Take out the toner/cartridges
Wait 30 sec
Plug the power cord back into the printer and wall (Make sure the printer is plugged into the wall and not a surge protector)
Insert the toner/cartridges back into the printer
Let me know the outcome
