Solutions

Quick Diagnosis

The E5 error appears as a combination of a light and panel message. Test one cartridge at a time; if the error disappears when one is removed, the issue is isolated to that specific unit, confirming why my HP ENVY Pro 6455 shows error E5.

Step-by-Step Solution

  1. Turn on the printer and open the cartridge door.
  2. Gently remove the ink cartridges.
  3. Clean the golden chip contacts on the cartridges using a lint-free cloth.
  4. Clean the internal carriage contacts with a dry, clean swab.
  5. Reinsert both cartridges until they snap into place.

Maintenance and Prevention

Never touch the chip contacts with skin, as oils can cause communication errors. Use genuine cartridges to ensure proper handshake with the firmware. Keep the printer away from dusty environments to protect internal contacts.

If the error persists after multiple reinstallation attempts and contact cleaning, the print carriage assembly might be faulty. Please contact support for hardware diagnostics.
