HP ENVY 6055e All-in-One Wireless Printer with Auto 2-Sided Printing and Smart App Integration MECH-07 Error Fix: Scanner Glass Dirty or Scratched

Error code MECH-07 on the HP ENVY 6055e All-in-One Wireless Printer with Auto 2-Sided Printing and Smart App Integration means: Scanner Glass Dirty or Scratched. Copies and scans show lines, smudges, spots, or recurring marks — the flatbed scanner glass has fingerprints, dust, ink marks, or scratches; clean the glass with a soft lint-free cloth and glass cleaner (spray the cloth, not the glass directly); also clean the underside of the scanner lid (the white backing material) as marks there will affect copies; a persistent line or streak in the same position on every scan indicates a scratch on the glass that cannot be cleaned and requires glass replacement; when scanning, ensure originals are placed face-down and flush against the registration marks on the glass
