Diagnosis
The primary issue with the Brother MFC-J1010DW is a disconnect between the hardware's "Scan to PC" function and the software's "ControlCenter4" configuration. Most users attempt to initiate the scan from the printer's physical touchscreen, but the printer cannot "push" a file to a computer unless a specific network handshake and folder destination have been established in the background software. If the computer isn't actively listening for the scan request, the printer will return a "Connection Failed" or "Unable to find PC" error. Furthermore, Brother's default installation often installs a "Lite" driver version that supports printing but lacks the TWAIN drivers necessary for scanning. To confirm this, check your Device Manager under 'Imaging Devices'; if you only see a generic USB device or nothing at all, the software is the bottleneck. The confusion stems from the software suite offering three different ways to scan—ControlCenter4, Brother iPrint&Scan, and the native OS utility—which often conflict with one another.
How to Fix It
For the most stable and consistent results, bypass the "Scan to PC" button on the printer and "pull" the scan from your computer using the Brother iPrint&Scan desktop application. This eliminates the network handshake errors.
- Ensure the MFC-J1010DW is connected to your Wi-Fi (2.4GHz is most stable for this model). Confirm the IP address on the printer by navigating to Settings > Network > WLAN > TCP/IP.
- Download and install the Brother iPrint&Scan app from the official support site. This replaces the dated ControlCenter4 software.
- Launch iPrint&Scan and select Machine Selection. Choose your MFC-J1010DW from the list. If it doesn't appear, manually enter the IP address found in step 1.
- Place your document face-down on the scanner glass (aligning with the top-left corner) or load the Automatic Document Feeder (ADF) for multi-page scans.
- In the software, click the Scan button. Select your "Scan Settings" (e.g., Color, 300 dpi, A4 or Letter size).
- Click Scan. Once the image appears in the preview window, click Save and choose your destination folder (typically 'Documents' or 'Pictures').
If That Didn't Work
- Disable Windows Firewall Restrictions: The Brother software often gets blocked by the Windows Defender Firewall. Go to Control Panel > System and Security > Windows Defender Firewall > Allow an app or feature. Ensure "Brother ControlCenter" and "iPrint&Scan" are checked for both Private and Public networks.
- Reinstall the Full Driver & Software Package: If the scanner isn't detected, you likely have the "Class Driver" installed by Windows Update. Uninstall all Brother software, restart, and install the "Full Driver & Software Package" specifically for the MFC-J1010DW. This installs the critical TWAIN driver.
- Use the Windows Scan App: If Brother's software remains unstable, download the official Microsoft Scan app from the Windows Store. It uses a simplified WIA (Windows Image Acquisition) protocol that bypasses Brother's complex software layers.
- Hard Reset the Network Card: Unplug the printer from the power source and the router. Wait 60 seconds. Plug the router in first, then the printer. This clears the DNS cache and often resolves "Unable to find PC" errors.
Heads Up
- ADF Cleaning: If you experience streaks on scans using the Automatic Document Feeder, clean the thin strip of glass to the left of the main scanner bed with a lint-free cloth and a tiny amount of isopropyl alcohol.
- PDF vs JPEG: Always use PDF for multi-page documents; the MFC-J1010DW can struggle with memory if you attempt to save 20+ pages as high-resolution JPEGs.
- Sleep Mode: This model has a "Deep Sleep" mode. If the scan fails to start, press any button on the printer to wake it up before clicking "Scan" on your computer.
- Resolution Balance: Do not scan at 1200 dpi unless absolutely necessary for photos; it will significantly slow down the transfer speed over Wi-Fi and may cause the software to time out.
