Hello Krentz,
Welcome to the HP Forums! I understand you are receiving color lines when scanning a document. Please make sure this printer is plugged into a direct wall, not a surge protector. HP recommends this step, as the color lines could disappear.
Please follow this HP document on Vertical Bands, Lines, or Streaks in Copies or Scans.
Let me know if this document resolves your issue or not.
Looking forward to hearing from you.
