The HP Smart Tank 585 error E7 indicates a critical failure in the connection or detection of the printheads.

Solutions

Diagnostic quick guide

The E7 error is distinguished by rhythmic blinking of warning lights without the printer attempting any loading movements. This means the printer does not recognize the physical presence of the printheads.

Step-by-step solution

  1. Access: Turn off the printer and open the printhead access cover.
  2. Removal: Lift the blue locking lever and carefully remove the printheads.
  3. Contact cleaning: Wipe a clean, dry cloth across the golden metal points of the printhead.
  4. Reinstallation: Place them back in position, press the lever down until you hear a 'click', and close the cover.

Prevention and maintenance

Never touch the metal contacts with your fingers; oils from the skin can damage them. Keep the environment free of excessive dust and perform printhead cleanings from the printer menu if you notice poor quality.

When to call a technician

If after cleaning contacts and reinstalling printheads the E7 error remains, the printhead may have internally burned out and will need full replacement with an original unit.
