HP Smart Tank 515 Error E14: Printhead Failure

The HP Smart Tank 515 is an all-in-one inkjet printer with high-yield ink tanks, designed for users requiring high volumes of printing at a low cost. Error E14 appears when the printer fails to correctly detect one or both printheads. This error is critical because, without communication with the printheads, the printer cannot process ink ejection or alignment. It is a common fault often caused by dirty electrical contacts or improper seating after maintenance, and it is usually easily resolved with proper cleaning.

Solutions

Diagnóstico rápido

Error E14 is indicated by an alert icon flashing on the LCD panel. It generally means the logic board is not receiving the electrical signal from the printhead (black or color). Ensure the carriage is in the center position.

Solución paso a paso

  1. Open the printhead access door while the printer is powered on.
  2. Remove the printhead that is triggering the error, carefully clean the gold contacts with a dry, lint-free cloth.
  3. Reinsert the printhead, ensuring you hear a firm click when the blue lock closes.
  4. Close the lids and wait for the printer to perform its automatic self-cleaning cycle.

Prevención y mantenimiento

  • Purge the printheads via software every 3 months if print volume is low to prevent ink drying.
  • Never touch the gold contacts with your fingers to avoid static discharge or grease buildup.
  • Maintain ink tank levels above the minimum mark to prevent air intake into the printhead assembly.

Cuándo llamar a un técnico

If the E14 error persists after cleaning the contacts, the printhead chip might be faulty, or the carriage flexible cable (FPC) might be damaged, requiring professional repair.

Try cleaning the contacts first. If the error continues, it is likely the printhead has reached the end of its life.

This printer uses HP M0H50A for black and M0H51A for color.

Run preventive cleaning cycles via software if you notice print streaks or at least every few months if the printer is not used regularly.
