        "content": "If JAWS is saying \u201cno device connected\u201d when you try to use OCR Capture with your Brother MFC-L3740, it means JAWS is not detecting the scanner interface it needs\u2014usually a TWAIN or WIA driver. Here are likely causes and how to fix them step by step:\n\n---\n\n## What\u2019s going on\n\n- The *Convenient OCR* feature in JAWS requires a **TWAIN-compatible scanner** or another supported scanning interface. If there is no such interface available, JAWS cannot use the scanner. ([sastltd.zohodesk.eu](https://sastltd.zohodesk.eu/portal/en/kb/articles/jaws-set-the-scanning-source-for-convenient-ocr?utm_source=openai))  \n- The Brother MFC-L3740 *(also sold as MFC-L3740CDW / L3740CDWE in some regions)* has support for both **WIA** and **TWAIN** scanning interfaces according to the official driver listings. ([store.brother.co.uk](https://store.brother.co.uk/devices/laser/mfc/mfcl3740cdw?utm_source=openai))  \n- If the scanner driver isn\u2019t properly installed, or if the scanner is connected via a method that isn\u2019t supported by TWAIN (or by what JAWS is expecting), JAWS won\u2019t see it.  \n\n---\n\n## How to fix it\n\nHere\u2019s what to check and how to correct the setup:\n\n| \u2714 | What to Check | How to Fix / Steps |\n|---|----------------|---------------------|\n| **1** | Driver type (TWAIN/WIA) is installed and correct. | - Go to Brother\u2019s support site, download *Printer & Scanner Driver for USB* or appropriate network drivers. It should list WIA and TWAIN in the driver description. ([support.brother.com](https://support.brother.com/g/b/downloadlist.aspx?c=gb&dlid=dlf105694_000&lang=en&os=10013&prod=mfcl3740cdw_eu&type3=536&utm_source=openai)) <br> - Install the correct driver for your connection type (USB, wired network, or wireless). |\n| **2** | Scanner is powered on and properly connected. | - If USB: check the cable, try different USB ports, make sure there is no damage. <br> - If network: ensure the printer/scanner has a valid IP, is connected to the same network as your PC. <br> - On the device panel, check network status. |\n| **3** | Windows detects the scanner. | - In **Settings \u2192 Bluetooth & devices \u2192 Printers & scanners**, the device should appear both as a printer and a scanner. <br> - In **Device Manager**, look for the scanner under \u201cImaging devices\u201d or \u201cUniversal Serial Bus controllers\u201d; check for yellow warning icons indicating driver problems. If it shows up only as a printer (and not as an imaging device), the scanner driver is likely missing. |\n| **4** | JAWS is set to use the correct acquisition source. | - In JAWS, open the JAWS window (JAWSKey + J), press **ALT + U** for Utilities.<br> - Navigate to *Convenient OCR* \u2192 *Cameras and Scanners*.<br> - From there, under *Camera and Scanners*, open the drop-down list and select an interface that shows \u201cTWAIN\u201d in the entry. If no TWAIN entry is shown, that\u2019s why JAWS isn\u2019t seeing the scanner. ([sastltd.zohodesk.eu](https://sastltd.zohodesk.eu/portal/en/kb/articles/jaws-set-the-scanning-source-for-convenient-ocr?utm_source=openai)) |\n| **5** | Driver software and services are running. | - Ensure Brother\u2019s scanning/WIA service is running (for example, *Windows Image Acquisition (WIA)*). <br> - If installed software includes Brother\u2019s \u201cControlCenter\u201d or similar utility, ensure it was installed fully, not partially. <br> - If there are firewall or antivirus settings blocking device discovery (especially for networked scanner), disable temporarily to test. |\n| **6** | Reinstall or update drivers if needed. | - Remove existing Brother scanner drivers. <br> - Download the latest version from Brother for your exact model. <br> - After installing, restart the PC. <br> - After rebooting, check if Windows sees the scanner and then test in JAWS\u2019s OCR Capture. |\n\n---\n\n## Common pitfalls\n\n- **Wrong connection type**: Using wireless when USB drivers with TWAIN weren\u2019t installed correctly.\n- **Minimal driver installations**: Sometimes driver packages install only printing features, not scanning.\n- **Not using an account with administrator rights**, which may block installation of certain drivers or services. ([techyorker.com](https://techyorker.com/how-to-fix-brother-scanner-not-working-in-windows-11/?utm_source=openai))  \n- **Security software or firewall interfering**, especially if the scanner is networked.  \n- **JAWS not set to TWAIN source**, or no TWAIN device option listed.  \n\n---\n\nIf you want, I can walk you through exactly what menu options to use in Windows and JAWS to set it up start-to-finish, with your specific screen reader version. Do you want to try that?"
