How to Fix Epson Workforce 545 Printer Error With No Code Displayed

Question: My Epson Workforce 545 shows a “Printer error” message without any specific error code. It keeps telling me to turn the printer off and back on again. I’ve changed the ink, cleaned the print heads, and even got it to start once, but the error keeps coming back. What can I do?

Understanding the “Printer Error – Turn Off and On Again” Message on Epson Workforce 545

When an Epson printer like the Workforce 545 shows a “Printer error” message without an error code, this typically signals a critical hardware fault. Here are the most common causes—and the steps you can take to troubleshoot them.

1. Printhead Drawing Excessive Current

This is one of the most likely causes. If the printhead is failing internally (due to a short circuit or degradation), it can draw too much electrical current during operation. Epson printers are designed with protective circuits that shut down the system if the current goes beyond safe limits.

Clue: You mentioned that the printer briefly came back to life after a head cleaning, then failed again during a nozzle check. That sudden failure during printhead movement suggests the issue may be triggered by electrical overload.

What You Can Try:

• Disconnect the printhead cable from the mainboard (you’ll need to open the printer to access it).

• Power the printer back on with the printhead disconnected.

• If the error changes (for example, to a "missing printhead" message), this confirms the printhead is the faulty component.

If confirmed, the only fix would be to replace the printhead. However, on a printer like the 545, parts may be hard to find or not worth the repair cost.

2. Failing Mainboard

If the printhead is ruled out, the next suspect is the main logic board. These boards can suffer from electrical surges or internal component wear, especially in older models.

Signs include:

• The printer fails at the same stage every time.

• There's no motor movement or sound during boot-up.

• The error message appears instantly at startup.

Unfortunately, replacing a mainboard requires finding a compatible used part, and installation often isn't user-friendly for most people.

3. Sensor or Mechanism Jam

Although less likely in your case, sometimes mechanical obstructions or sensor alignment errors can also produce a generic printer error. Since you already cleaned the printheads and got the printer to respond temporarily, a full carriage jam seems unlikely—but still worth checking:

• Make sure the carriage moves freely when the printer is off.

• Check that paper feed rollers and internal cogs are not jammed or out of place.

• Look for any signs of moisture or spilled ink around cable terminals.

4. Firmware or Software Glitch

If none of the hardware issues above check out, consider trying a hard reset:

• Unplug the printer.

• Hold the power button for 30 seconds to discharge residual energy.

• Reconnect and power on again.

Also, avoid firmware updates if the printer has been used with non-OEM cartridges or third-party ink systems, as this can cause compatibility problems.

Addressing printer issues like this can be challenging due to the hands-on nature of diagnosis and repair. As such, we're unable to provide remote support or step-by-step troubleshooting for these types of problems. However, we do offer in-person evaluation and repair through our local diagnostic facility (https://bchtechnologies.com/printer-repair-service).
