0xF4
Epson Printer
Severity: CriticalWhat Does This Error Mean?
Epson error 0xF4 is a critical internal hardware error. The printer's main board detected a failure it cannot recover from by itself. This error is similar in severity to the infamous 0x97 error and usually means the printer needs repair or replacement.
Affected Models
- Epson WorkForce WF-2850
- Epson WorkForce WF-3820
- Epson WorkForce Pro WF-4830
- Epson EcoTank ET-3850
- Epson Expression XP-7100
Common Causes
- A power surge or voltage spike damaged the printer's main circuit board
- The printer was turned off suddenly during a print job, leaving the print head in a bad position and causing it to overheat
- Dried or clogged ink in the print head caused it to overheat and trigger a safety shutdown
- An internal component such as the print head driver circuit has failed due to age or wear
- The printer's firmware became corrupted — for example, due to a failed update or power loss during an update
How to Fix It
-
Unplug the printer from the wall completely. Wait 10 full minutes. This is longer than a normal restart — the extended wait allows internal components to fully discharge.
Some users have reported that a 10-minute wait resolved a 0xF4 error that a normal restart did not fix. It is the simplest thing to try first.
-
After the 10-minute wait, plug the printer back in and power it on. Watch the startup sequence carefully — listen for any unusual sounds (grinding, clicking, or repeated thumping).
Normal startup involves the print head moving left and right briefly. Unusual sounds during startup suggest a mechanical fault in the print head carriage.
-
If the printer starts without the error, run a nozzle check immediately from the printer's maintenance menu. Inspect the result — if many nozzles are blocked, run a cleaning cycle.
A severely clogged print head can cause overheating and trigger error 0xF4. Clearing the clog may prevent the error from returning.
-
Check if a firmware update is available for your printer model on Epson's website. If the error was triggered by a failed firmware update, reinstalling clean firmware may fix it.
When downloading firmware, make sure your internet connection is stable. A second interrupted firmware update will make the situation worse.
-
If the error 0xF4 returns immediately on startup — before you can do anything — the main board or print head has failed and requires professional replacement.
Contact Epson support at epson.com/support or find a local authorized service center. Provide your printer's model number and serial number when you call.
When to Call a Professional
Error 0xF4 is flagged as critical because it often requires hardware intervention. If the steps below do not resolve it, contact Epson support or visit an authorized Epson service center. For printers older than 3 years, compare the repair estimate with the cost of a new printer before committing to a repair.
Frequently Asked Questions
Is error 0xF4 always fatal for an Epson printer?
No, not always. Some users resolve it with a long power cycle or a firmware reinstall. However, it does indicate a serious problem — either hardware that has failed, or firmware that is critically damaged. Do not ignore it or keep using the printer while it is showing this error.
My Epson printer is under a year old and shows error 0xF4 — is it covered by warranty?
Yes, Epson printers come with a 1-year limited warranty in most countries. Contact Epson support with your proof of purchase and they will arrange a repair or replacement at no cost. Visit epson.com/support to start a warranty claim — do not attempt repairs yourself on a printer still under warranty.
I saw a YouTube video saying I can fix 0xF4 by holding buttons during startup — does that work?
Some Epson models have a factory reset or service mode that can be entered by holding certain button combinations during startup. This sometimes clears a corrupted firmware state and resolves the error. The exact button combination is model-specific — search for your model name plus 'factory reset' or 'service mode' to find the right steps. Be aware this will reset all your settings.
