Problem
The ScanSnap iX1600 enters sleep mode but fails to wake properly when you press the touchscreen or attempt to scan. The screen may remain dark, the device may appear powered on but unresponsive, or it may require a full power cycle to function again. In some cases, the scanner disconnects from the computer after sleep and does not automatically reconnect.
This issue is typically related to power management settings, firmware glitches, USB sleep behaviour, or network reconnection delays.
Solution
Adjusting power settings, updating firmware, disabling aggressive USB power saving, and confirming stable WiFi connectivity usually resolves sleep and wake problems. Identifying whether the issue occurs over USB or WiFi is key to applying the correct fix.
Step-by-step instructions
Perform a full power reset
Turn off the scanner using the power button. Disconnect the power cable for at least 60 seconds. Reconnect the cable and power the scanner back on. Test sleep and wake behaviour again.
Update scanner firmware
On the touchscreen, open Settings and check for firmware updates. Install any available updates to address stability or wake related bugs.
Adjust sleep timer settings
From the scanner Settings menu, review the automatic sleep timer. Extend the sleep interval or temporarily disable it for testing purposes.
Check USB power management on Windows
If connected via USB, open Device Manager. Locate the USB Root Hub settings and disable the option that allows the computer to turn off the device to save power. Restart the computer and test again.
Test without USB connection
Disconnect the USB cable and use WiFi only. If wake behaviour improves, the issue may be related to USB power saving.
Confirm WiFi stability
If using WiFi, ensure the scanner reconnects to the network after sleep. Weak signal strength or router delays can prevent automatic reconnection.
Re register the scanner in ScanSnap Home
If the device does not reconnect after sleep, remove it from ScanSnap Home and add it again to refresh the connection profile.
Optional methods or tools
Plug the scanner directly into a wall outlet rather than an extension lead to ensure consistent power delivery.
If your computer enters deep sleep frequently, adjust system sleep settings to test compatibility.
Temporarily disable VPN software to prevent network reconnection delays.
Best practices or tips
Keep firmware updated to reduce power management bugs.
Avoid repeatedly forcing shutdowns, as this may corrupt settings.
Ensure your router firmware is current if using WiFi.
Restart the scanner occasionally if used continuously throughout the day.
Sleep and wake issues with the ScanSnap iX1600 are usually linked to power management behaviour rather than hardware failure. USB power saving features and unstable wireless reconnection are common causes of the scanner appearing unresponsive after standby.
By adjusting sleep timers, disabling aggressive power saving, and ensuring stable network connectivity, you can restore reliable wake behaviour. Once configured correctly, the ScanSnap iX1600 should resume operation quickly whenever you are ready to scan.
