HP Smart Tank Plus 651 Error E6: Initialization Failure

The HP Smart Tank Plus 651 error E6 is a critical system initialization failure. When the printer throws this code, it means the logic board has encountered a serious inconsistency while trying to start the internal firmware, preventing the device from moving to ready state. This error is complex and often stems from an electrical interruption during an update or a data integrity failure in the device's internal memory.

Common causes

  • 1Integrity failure in the logic board firmware.
  • 2Electrical interruption during a critical update.
  • 3Data corruption in Non-Volatile RAM (NVRAM).
  • 4Electronic fault in mainboard circuits.

Solutions

Quick Diagnostics

The E6 error appears on the screen as soon as you try to turn on the unit. Unlike mechanical errors, there are no motor noises or movement; the printer simply refuses to perform the standard startup cycle, remaining stuck in error mode.

Step-by-step Solution

  1. Disconnect the printer from power and wait at least 5 minutes before trying to turn it on again.
  2. If the printer turns on but stays in E6, try connecting it via USB to a computer to see if the HP Smart app recognizes it.
  3. Look for the 'Update firmware' or 'Recover device' option within the HP software suite on your computer.
  4. If the device is not recognized by any computer, software recovery options are exhausted.

Prevention and Maintenance

Never disconnect the printer while it is installing a firmware update. Always use a voltage regulator to prevent power surges from damaging logic components.

When to call a technician

If the E6 error remains after several power cycles and is not recognized by recovery software, the main logic board is permanently damaged and needs replacement.

Frequently asked questions

Not necessarily, but it is an internal system error suggesting the logic board is stuck in an error loop.

If the printer can connect via USB, HP software can attempt a firmware recovery.

It usually occurs after an interrupted firmware update or a sudden internal memory fault in the printer.

It is a high-level code. If basic steps don't work, the main hardware might require replacement.
