  • 1Hardware wear on the internal drive mechanism.
  • 2Corruption of the core OS partition.
  • 3Power surge damaging the drive logic board.
  • 4Loose connection to the SATA/storage interface.

Solutions

Quick Diagnosis

The device stalls during boot or displays a permanent system error screen. This code signals that the main processor cannot retrieve the OS data from the internal hard drive. It is a fundamental hardware-software handshake failure.

Step-by-Step Fix

  1. Forced power-off: Unplug the machine completely for 5 minutes to clear static from the main controller board.
  2. Restart: Turn the device on and watch the boot screen for any signs of progress.
  3. Firmware intervention: If the boot sequence remains stuck on E602, the firmware may require a fresh installation by a professional.

Maintenance and Prevention

Using an Uninterruptible Power Supply (UPS) is highly recommended to prevent corruption of the hard drive during power spikes. Never unplug the machine while it is finishing a print cycle. Genuine toner ensures long-term machine stability.

When to Call a Technician

If the machine fails to boot after a restart, the internal hard drive has likely suffered a hardware failure and needs to be replaced.
