Frequently Asked Questions


Why is my Brother scanner not working?
Check power connection, verify USB or Wi-Fi connectivity, restart the scanner and computer, and ensure drivers are properly installed.
Why is my Brother scanner producing blank scans?
Incorrect document placement, dirty scanner glass, lid not fully closed, or scan settings issues may cause blank scan output.
Why is my Brother scanner showing offline?
Check USB, Ethernet, or Wi-Fi connectivity, restart the scanner and computer, and ensure the scanner is selected as the default device.
Why is my Brother scanner not connecting to Wi-Fi?
Incorrect network settings, weak wireless signal, router issues, or outdated firmware may prevent successful Wi-Fi connections.
Why is my Brother scanner producing poor quality scans?
Dirty scanner glass, low resolution settings, poor document placement, or calibration issues can reduce scan quality.
Why are there lines or streaks on my scanned images?
Dust on the scanner glass, dirty sensors, scratches on the glass, or calibration issues commonly cause streaks and lines.
