Error E-0004 Epson SureColor S60600L: Voltage fault

Epson SureColor S60600L error E-0004 is a system alert indicating an inconsistency in the voltage supplied to the printheads. This error typically appears due to electrical fluctuations or faults in the print carriage data bus. It is a relevant technical notice that requires precise electrical diagnostics to avoid costly printhead damage.

Common causes

  • 1Instability in the facility's electrical line.
  • 2Fault in the printhead controller board capacitors.
  • 3Physical wear of the print carriage data cable.
  • 4Excessive humidity causing condensation on components.

Solutions

Quick Diagnosis

If the touch panel displays the code E-0004, check first for recent power surges or outages. The SureColor system performs self-protection if current is unstable, so it is vital to ensure the power environment is correct before handling the machine.

Step-by-step Solution

  1. Stabilize power: Ensure the equipment is not shared on a line with motors or high-demand devices.
  2. Long power cycle: Leave the unit unplugged for at least 30 minutes to allow capacitors to discharge.
  3. Visual inspection: Check the flexible flat cable (FFC) of the carriage for signs of burning or wear from rubbing.
  4. Software Diagnostics: Use Epson's diagnostic software to reset the hardware alert after ensuring electrical stability.

Prevention and Maintenance

Use a dedicated UPS of at least 3kVA. Cleaning of printhead contacts must be done following service manuals. It is crucial to avoid environmental humidity above 60% to prevent electrical arcing in circuitry.

When to call a technician

If the error persists after power stabilization, it is highly likely that the printhead board or the flat cable has suffered a short-circuit fault that can only be resolved by replacing genuine parts.

Steps to follow

  1. 1

    Electrical verification

    Check that the voltage stabilizer connected to the printer is providing constant power.

  2. 2

    Forced shutdown

    Turn off the bulk ink system and disconnect the printer from the mains for 30 minutes.

  3. 3

    Wiring inspection

    Inspect the cables connecting the print carriage for visible damage or loose connections.

  4. 4

    System reset

    Turn on the unit and perform a nozzle check to rule out permanent printhead failure.

Frequently asked questions

This error appears when the control system detects voltage fluctuations in the printhead power supply, protecting internal circuits from further damage.

Yes, it should be addressed immediately, as operating with unstable voltages can permanently burn printhead nozzles.

This printer uses Epson UltraChrome GS3 eco-solvent inks; low ink levels or poorly placed ink bags can affect carriage weight and electrical behavior.

Keep the printer connected to a properly sized Uninterruptible Power Supply (UPS) as it is a large-scale equipment.
