Epson Printer Error 0x97 — What It Means & How to Fix It

What Does This Error Mean?

Error 0x97 is a critical hardware error on Epson printers. The printer's internal system has encountered a fatal fault and shut itself down. This is one of the most serious Epson error codes — it often indicates a main board failure.

Affected Models

Epson WorkForce WF-3620

Common Causes

The printer's main circuit board has failed due to age or a power surge
The print head has developed an internal short circuit that is affecting the main board
A power surge or voltage spike caused permanent damage to internal components
Ink has leaked internally and reached the main board, causing a short
The printer has been used far beyond its rated duty cycle, causing critical component failure

How to Fix It

Turn off the printer. Unplug all cables — power cord and USB or network cables. Wait at least 5 minutes.

A full power disconnect (not just the power button) is needed to attempt a complete reset of the internal electronics.
Remove all ink cartridges from the printer. Set them aside on a clean paper towel.

Some users report the 0x97 error clearing after removing cartridges and doing a full power cycle, though this is not a guaranteed fix.
Hold the power button on the printer for 1 minute while it is unplugged. This discharges any residual electricity from the capacitors.

This step helps ensure a completely clean restart without any previous fault state remaining in the electronics.
Reconnect only the power cable (leave cartridges out, leave USB or network disconnected). Power the printer on and see if the error appears without cartridges installed.

If the printer starts without error when cartridges are removed, a faulty cartridge may be contributing to the fault.
If the error persists, contact Epson support at their official website. Provide your printer model and serial number. Ask about any known service programs for this error.

Epson has offered free repairs or replacements for 0x97 errors on certain WorkForce models due to the widespread nature of the problem.

When to Call a Professional

Error 0x97 almost always requires professional diagnosis or printer replacement. The main board replacement for affected Epson WorkForce models can cost as much as a new printer. Epson acknowledged this issue on some models — contact Epson support to see if your printer is covered by any extended service program.

Frequently Asked Questions

Is error 0x97 covered under warranty?

If your printer is still within its standard warranty period (usually 1 year), Epson should repair or replace it at no cost. For out-of-warranty printers, Epson has offered repair programs for some WorkForce models specifically affected by 0x97. Contact Epson support with your serial number to find out what options are available for your specific printer.

Is it worth repairing a printer with error 0x97?

Usually not. Main board replacement typically costs as much as — or more than — a new printer. Unless your printer has special value (such as a large format or business-grade model), buying a replacement is often the smarter financial decision. Check repair quotes against the current price of a replacement printer before committing to a repair.

Why do so many Epson WorkForce printers get 0x97?

Epson's WorkForce series from the mid-2010s had a documented issue with their main boards failing after a few years of use. The exact cause is debated — some believe it is a design flaw, others blame ink leakage reaching the board. Epson has acknowledged the issue on some specific models and offered remedies.
