Common causes

  • 1Firmware corruption during interrupted updates.
  • 2Voltage surges affecting ROM registers.
  • 3Faulty cartridge chip causing logic interference.
  • 4Flash memory exhaustion from frequent use cycles.

Solutions

Quick Diagnosis

If the printer locks on the 0x9d screen immediately upon startup, perform a hard reset by unplugging the unit from mains power for 10 full minutes.

Step-by-step Solution

  1. Hard Reset: Power off and unplug the power cord for 10 minutes.
  2. USB Update: Connect the printer to a PC via USB and download the official Epson firmware utility.
  3. Execution: Launch the utility; it should recognize the printer even if the internal logic is in a partial state.
  4. Check Chips: Inspect cartridge chips for dirt or damage, as faulty chips can trigger logic errors.

Prevention and Maintenance

Use a surge protector. Never interrupt the printer during software updates. Use only original consumables to ensure stable chip-to-board communication.

When to Call a Technician

If the error persists after a forced update, the internal ROM memory might be physically damaged, requiring a mainboard replacement.

  3. 3

    Check cartridges

    Ensure cartridge chips are clean; a faulty chip can interfere with internal logic.

Frequently asked questions

The 0x9d is a critical communication error between the main logic board and the printer firmware, typically following an interrupted update.

Usually not; it is a logical error. A manual firmware update via USB is often enough to restore the software.

While this is a system error, cartridge chips sometimes send corrupted signals that confuse the logic board.

Always keep the device connected to a stable power supply and never turn it off during an update process.
