What is Windows System Error Code ERROR_205?
Before diving into fixes, let’s understand what ERROR_205 actually means. The error message typically says:
“ERROR_205: The device is not connected (or is unavailable).”
This code appears when Windows is unable to communicate with a device, often due to connectivity issues, driver problems, or device malfunctions. It’s common with printers, external drives, or network resources that are unplugged, offline, or misconfigured.
Common Causes of ERROR_205
- Device physically disconnected or powered off
- Outdated, missing, or corrupt device drivers
- Network configuration issues (for network devices)
- Conflicts with other software or hardware
- Corrupted system files affecting device management
Step-by-Step Guide to Fix ERROR_205
Step 1: Verify Device Connection and Power State
Start with the most straightforward check:
- Check physical connections — Ensure cables (USB, Ethernet, or power cables) are properly plugged in. For wireless devices, verify they are connected to the correct network.
- Power cycle the device — Turn the device off, wait 10 seconds, and then turn it back on.
- Try a different port or cable — Sometimes USB or network ports malfunction, so switch ports or replace cables.
If the device remains unavailable, proceed to the next steps.
Step 2: Restart Your Computer
A simple reboot can fix temporary glitches:
- Click on Start > Power > Restart.
- After your PC restarts, check if the device is now recognized.
Step 3: Run the Windows Troubleshooter
Windows includes built-in troubleshooters tailored for common issues, including device errors:
- Press Windows + I to open Settings.
- Go to Update & Security > Troubleshoot > Additional troubleshooters.
- Select Printer (if your device is a printer) or other relevant troubleshooters.
- Click Run the troubleshooter and follow the prompts.
This tool can automatically detect and fix problems causing ERROR_205.
Step 4: Update or Reinstall Device Drivers
Drivers are the software interfaces between Windows and your hardware. Corrupted or outdated drivers can cause ERROR_205.
Update Device Drivers:
- Press Windows + X and select Device Manager.
- Locate your device in the list (e.g., under Printers, Universal Serial Bus controllers, or Network adapters).

- Choose Search automatically for updated driver software.
- Follow the instructions to install the latest drivers.
Reinstall Device Drivers (if updating doesn’t work):
- In Device Manager, right-click the problematic device and select Uninstall device.
- Restart your PC. Windows will attempt to reinstall the driver automatically.
- If Windows doesn’t reinstall the driver, visit the manufacturer’s website to download and manually install the latest driver.
Step 5: Check Network Configuration (For Network Devices)
If ERROR_205 relates to a network printer or device:
- Ensure your PC and the device are on the same network.
- Confirm IP addresses have not changed unexpectedly—static IPs often help.
- Disable any VPN or firewall temporarily to test if they’re blocking communication.
- In some cases, running the command
ipconfig /flushdnsin Command Prompt can help clear network cache. - Use the command
ping [device IP address]to check if your system can reach the device.
Step 6: Scan and Repair Corrupted System Files
System file corruption can also cause device errors:
- Open Command Prompt as Administrator (search for “cmd” > Right-click > Run as administrator).
- Type
sfc /scannowand press Enter. - Wait for the tool to scan and repair corrupted files.
- Restart your PC when the process completes.
Step 7: Check Device Status in Services
Some devices depend on Windows services to function:
- Press Windows + R, type
services.mscand press Enter. - Locate services related to your device. For printers, check Print Spooler.
- Make sure the service status is Running.
- If not, right-click and select Start or Restart.
