# **1. Common Reasons Why Epson ET-3850 Goes Offline**

Before you begin fixing the problem, it helps to understand what causes it. Some common reasons include:

### ✔ Weak Wi-Fi signal or disconnection

If the printer is too far from the router, the connection may drop.

### ✔ Incorrect printer settings

“Use Printer Offline” mode or wrong default printer settings can cause this issue.

### ✔ Outdated or corrupt printer drivers

Drivers tell your computer how to operate your printer. Outdated drivers can cause miscommunication.

### ✔ USB cable problems

A loose or damaged USB cable can stop the printer from communicating.

### ✔ Network conflict or power outage

Network changes, firmware updates, or sudden power cuts often disconnect the printer.

### ✔ IP address changes on the printer

If the printer’s IP changes but the computer still uses the old one, the printer may appear offline.

### ✔ Print spooler service issues

When the spooler service stops, your printer becomes unresponsive.

Understanding the cause makes the troubleshooting process faster and easier.
