Epson Printer Error Code 0xE9 — What It Means & How to Fix It

What Does This Error Mean?

Epson error 0xE9 is a communication error between your computer and the printer. The printer received incomplete or corrupted data and cannot process the print job. This is usually caused by a connection problem, a driver issue, or a corrupted print job in the queue.

Affected Models

Epson WorkForce WF-3640
Epson WorkForce WF-4720
Epson Expression Premium XP-7100
Epson WorkForce Pro WF-4740
Epson EcoTank ET-4750

Common Causes

The USB or network cable has a loose connection or is damaged, causing data to be corrupted in transit
The printer driver on the computer is outdated, corrupted, or incompatible with the current operating system
A corrupted print job stuck in the print queue is sending bad data to the printer repeatedly
A firewall or security software on the computer is blocking the data communication with the printer
The printer's network connection dropped mid-print on a Wi-Fi or wired network setup

How to Fix It

Turn the printer off and on again. On your computer, open the print queue and cancel all pending print jobs.

A stuck or corrupted job in the queue often retriggers this error with each new print attempt. Clearing the queue gives the printer a clean start.
If using a USB connection, unplug the cable from both the printer and the computer. Plug it back in firmly to both ends.

Try a different USB port on your computer or a different USB cable entirely. A faulty cable is a surprisingly common cause of 0xE9.
If printing over Wi-Fi, confirm the printer is still connected to your network. Print a network status page from the printer's control panel.

If the printer shows a different IP address than expected, your router may have reassigned it. Reconnect the printer to Wi-Fi via the printer's network settings menu.
Uninstall your current Epson printer driver completely from your computer. Download the latest driver from Epson's official support website and reinstall it.

On Windows, go to Settings > Apps and search for Epson to uninstall the old driver. A fresh driver install resolves many communication errors.
Temporarily disable your firewall or antivirus software and try printing. If it works, add the Epson printer software to your security software's exception or whitelist.

Some security software aggressively blocks printer data ports, especially after an automatic update. Re-enable your security software after testing.

When to Call a Professional

If error 0xE9 returns consistently after trying all software and connection fixes, the printer's main board communication circuitry may be failing. This is uncommon but does occur on older printers. A technician can run a diagnostic and advise whether repair or replacement is the better option.

Frequently Asked Questions

Why does Epson error 0xE9 only happen with certain documents?

Some documents — particularly large PDFs or files with embedded fonts and complex graphics — send a much larger and more complex data stream to the printer. If the connection is marginal (slow network, slightly loose USB cable), small documents get through fine but large ones fail. Simplifying the document or converting it to a flat image before printing often helps.

I just updated Windows and now I get 0xE9. What happened?

Windows updates sometimes overwrite or replace printer drivers with a generic version that may not communicate correctly with your specific Epson model. Go to Epson's website, download the latest full driver package for your printer model, and reinstall it to restore full compatibility.

Can error 0xE9 corrupt my print job files?

No. The error occurs during the data transfer to the printer — your original files on the computer are not affected. Once you resolve the communication issue, you can resend the exact same files without any loss of data.
