Epson Error E-05 — What It Means & How to Fix It
Updated July 2026 · Independent PrinterCare USA support guide
The E-05 error on Epson printers is one of the most frustrating wireless issues you can encounter because everything looks fine on the surface, but your printer simply refuses to communicate with your network. This error typically appears when the printer loses its WiFi connection midway through a job or cannot establish a stable connection to your router in the first place.
The good news is that in most cases this is a straightforward fix that takes less than ten minutes and requires no technical expertise. We have helped hundreds of home and business users resolve this exact error by working through a systematic process that addresses the most common causes first, so you can get back to printing without unnecessary downtime.
How to fix it — step by step
- Restart Your Printer. Power off your Epson printer completely by switching off the power button, then wait for thirty seconds to allow all internal systems to fully discharge. Turn the printer back on and wait for it to fully initialize, which typically takes about two minutes. This simple restart clears temporary WiFi connection states that often cause the E-05 error.
- Restart Your Router. Unplug your WiFi router from the electrical outlet and wait for a full sixty seconds before plugging it back in. Allow the router to fully boot and establish all connections, which usually takes two to three minutes as indicated by the status lights. A fresh router restart resolves most wireless dropout issues across all connected devices.
- Check Your Network Band. Verify that your printer is connecting to the same WiFi band as your computer by checking your printer's network settings menu on the display panel. Most Epson printers work best on the 2.4 GHz band rather than 5 GHz, so if your router broadcasts both bands and your computer is on 5 GHz, switch your printer to 2.4 GHz. You can find this setting in the printer's WiFi setup menu under Network Settings or Wireless LAN Settings.
- Move Your Printer Closer to the Router. Relocate your Epson printer to within ten feet of your WiFi router and perform a test print to see if signal strength is the issue. Physical obstacles like walls, metal filing cabinets, and microwave ovens can severely weaken WiFi signals, so moving the printer temporarily will help you diagnose whether distance is the culprit. Once you confirm this is the problem, you can then explore options like adding a WiFi extender or repositioning your router.
- Perform a Network Reset on the Printer. Access the printer's main menu by pressing the Menu or Settings button on the control panel, then navigate to Network Settings and select Reset Network Settings or Initialize Network. The printer will restart and forget all saved WiFi networks, returning to factory network defaults. After the reset completes, you will need to reconnect the printer to your WiFi network using the standard setup process.
- Reinstall Your Printer on Windows or Mac. On Windows, open Settings, go to Devices, select Printers and Scanners, find your Epson printer, and click Remove Device. On Mac, open System Preferences, select Printers and Scanners, click your Epson printer, and select the minus button to delete it. After removing the printer from your system completely, download the latest driver from Epson's support website and reinstall both the driver and the printer connection using the setup wizard.
- Check Your Router's WiFi Password and Security Settings. Log into your router's admin panel by entering your router's IP address in a web browser, then verify that the WiFi password has not changed and that the security setting is not set to WPA3, which some older Epson printers cannot support. If WPA3 is enabled, change the security mode to WPA2 or WPA/WPA2 mixed mode, then attempt to reconnect your printer. Take note of your exact WiFi network name (SSID) and password to ensure you enter them correctly during printer setup.
- Contact Remote Technical Support. If none of the above steps resolve your E-05 error after working through them systematically, contact an Epson certified technician through a remote support service for fifty dollars, where they can access your printer remotely and diagnose more complex firmware or hardware issues. Remote technicians can often identify subtle network configuration problems or perform advanced diagnostics that are not available through standard troubleshooting guides. Many businesses find this option faster and more reliable than spending hours on support phone calls.

Frequently asked questions
Will the E-05 error damage my printer or cause data loss?
No, the E-05 error is purely a communication problem between your printer and your WiFi network and does not harm the printer hardware or erase any stored documents. The error simply means your print jobs cannot be transmitted to the printer, so nothing gets damaged during the process. Once you restore the WiFi connection using the steps above, your printer will function normally again.
Can I use a USB cable to bypass the E-05 error temporarily?
Yes, connecting your Epson printer directly to your computer using a USB cable will allow you to print immediately and bypass the WiFi connection problem. This temporary solution works on Windows and Mac systems and lets you continue printing while you troubleshoot the wireless issue. However, this does not fix the underlying E-05 error, so you should still work through the network reset steps to restore WiFi functionality.
Why does my printer keep getting the E-05 error even though my WiFi is working fine on other devices?
Epson printers are sometimes sensitive to specific router settings or WiFi bands that work fine for phones and computers but cause connection drops on the printer. Older Epson models especially struggle with 5 GHz networks and modern security protocols like WPA3, so switching to 2.4 GHz or WPA2 security mode often resolves this issue. If your other devices are all on 5 GHz, consider enabling a separate 2.4 GHz band on your router specifically for your printer and older IoT devices.
Is the E-05 error covered under Epson's warranty?
The E-05 error is typically not considered a hardware defect covered by Epson's standard warranty because it results from network connectivity problems rather than printer component failure. However, if your printer is still under warranty and all troubleshooting steps fail, you can contact Epson support to inquire whether they will cover a replacement or repair. Most home and business users resolve the E-05 error themselves through the steps provided above without needing to pursue warranty claims.
