        "content": "Yes \u2014 the HP LaserJet Pro MFP M28-M31 series *does* support wireless scanning, but it depends on having one of the wireless-capable models (marked with \u201cw\u201d, like M28w or M31w) and using correct settings.\n\nHere\u2019s what you need to know in detail:\n\n---\n\n### What \u201cwireless scanner\u201d means here\n\n- **Wireless scanning** means you can scan from a computer or mobile device over Wi-Fi, not just via a physical USB connection.\n- The printer itself is a multifunction device: it prints, scans (flatbed), and copies. The \u201cMFP\u201d in the name stands for Multifunction Printer. ([support.hp.com](https://support.hp.com/us-en/product/product-specs/hp-laserjet-pro-mfp-m28-m31-printer-series/model/16647088?utm_source=openai))\n\n---\n\n### Wireless capabilities of the M28-M31 series\n\n- Some models, like **M28w** and **M31w**, are wireless models. They include Wi-Fi networking and support mobile printing via AirPrint, Wi-Fi Direct, and other protocols. ([support.hp.com](https://support.hp.com/us-en/product/product-specs/hp-laserjet-pro-mfp-m28-m31-printer-series/model/16647088?utm_source=openai))\n- There are also \u201cbasic\u201d or \u201cnon-wireless\u201d versions (marked with \u201ca\u201d, \u201cnon-w\u201d, or just M28-M31 without a \u201cw\u201d) that may only connect via USB and possibly wired network, depending on the variant. The reference manual and specs make this distinction clear. ([manualmachine.com](https://manualmachine.com/hp/laserjetm28/2952271-reference-manual/?utm_source=openai))\n\n---\n\n### Does wireless scanning work?\n\n- Yes \u2014 if your specific model is a wireless version (e.g. M28w or M31w), scanning over Wi-Fi works. For example, the reference manual for wireless models describes how to scan on Windows or macOS via HP\u2019s scan utilities, TWAIN or WIA interfaces. ([manualmachine.com](https://manualmachine.com/hp/laserjetm28/2952271-reference-manual/?utm_source=openai))\n- HP also supports *Wi-Fi Direct* for mobile printing; while that\u2019s more about printing, the overall wireless networking in the device supports scan jobs over the same wireless network. ([laserexpressinc.com](https://www.laserexpressinc.com/manuals/HP/hp-lj-pro-m28-m31-user-manual.pdf?utm_source=openai))\n\n---\n\n### Things to check if it\u2019s not working\n\nIf scanning isn\u2019t working wirelessly, here's what to verify:\n\n1. **Model variant**: Make sure your printer has the \u201cw\u201d (wireless) version. If it doesn\u2019t, wireless scanning might not be supported.\n\n2. **Network setup**: The printer must be connected to the same Wi-Fi network as your computer or mobile device. If it\u2019s set up via Wi-Fi Direct, make sure that\u2019s enabled properly. ([laserexpressinc.com](https://www.laserexpressinc.com/manuals/HP/hp-lj-pro-m28-m31-user-manual.pdf?utm_source=openai))\n\n3. **Drivers/software**: Install the correct HP driver package (\u201cFull-feature driver\u201d or \"HP Universal Scan driver\") that recognizes scanner functionality. Sometimes the printer portion works, but the scanner isn\u2019t detected if drivers are incomplete. ([driver-hp.net](https://driver-hp.net/hp-laserjet-pro-mfp-m28-m31-driver/?utm_source=openai))\n\n4. **Firmware & updates**: Having the latest firmware helps, especially to enable and stabilize wireless and scanning features. ([bhphotovideo.com](https://www.bhphotovideo.com/lit_files/608213.pdf?utm_source=openai))\n\n---\n\nIf you tell me which exact model you have (for example, \u201cM28w\u201d vs \u201cM28a\u201d), I can help check whether your particular unit supports wireless scanning and guide you through getting it set up."

But to be certain, here are a few places and ways you can check:\n\n---\n\n## \u2705 1. Look at the model badge/label on the printer\n\n- Check the front, top or back of the printer \u2014 there should be a label with the **full model name**, such as **\u201cLaserJet Pro MFP M28w\u201d** or **\u201cM31w\u201d**. The **\u201cw\u201d** at the end indicates the wireless version.  \n- Sometimes this label is also inside the toner cartridge door or on the back panel near where the power cable is. ([manualmachine.com](https://manualmachine.com/hp/m28w/4696099-user-manual/?utm_source=openai))\n\n---\n\n## \ud83d\udd0d 2. Use the printer\u2019s control panel / menu system\n\n- Wireless models (M28w, M29w, M30w, M31w) typically show a **Wi-Fi icon** or have a dedicated **wireless/Wi-Fi button** or LED indicator. ([laserexpressinc.com](https://www.laserexpressinc.com/manuals/HP/hp-lj-pro-m28-m31-user-manual.pdf?utm_source=openai))  \n- The user manual for wireless models usually has sections for setting up Wi-Fi, Wi-Fi Direct, mobile printing, etc. If those are present, that's a strong sign it\u2019s a \u201cw\u201d model. ([manualmachine.com](https://manualmachine.com/hp/m28w/4696099-user-manual/?utm_source=openai))\n\n---\n\n## \ud83d\udda5 3. Check Windows 11\n\n- Go to **Settings \u2192 Bluetooth & Devices \u2192 Printers & Scanners**. Find your printer, click **Manage**, and open **Printer Properties**. The model name should include the \u201cw\u201d suffix if it\u2019s wireless.  \n- Alternatively, in Control Panel \u2192 Devices & Printers \u2192 right-click the printer \u2192 **Properties**, or use the **Details** tab. Some drivers or utilities will also show the full model in the driver/software suite. ([geekchamp.com](https://geekchamp.com/how-to-find-printer-model-and-serial-number-on-windows-11-10/?utm_source=openai))\n\n---\n\n## \ud83d\udcf1 4. Use the printer\u2019s embedded web server (EWS)\n\n- Since it\u2019s networked, you can often find its **IP address** either by printing a network status page (via the control panel) or from your router\u2019s DHCP client list.  \n- Paste the IP address into your web browser \u2192 look for the **About**, **Device Information**, **System Information**, or **Network** section. The full model name should appear there. ([manualslib.com](https://www.manualslib.com/manual/4062182/Hp-Mfp-M28w.html?utm_source=openai))\n\n---\n\nIf you'd like, I can walk you through how to use any of these methods step-by-step, especially with Windows 11 or via the printer itself.

I\u2019ll walk you through common causes and fixes, tailored for Windows 11 since that\u2019s what you\u2019re using.\n\n---\n\n## \ud83d\udd0d 1. Confirm the Computer Sees the Scanner\n\n- Go to **Start \u2192 Settings \u2192 Bluetooth & devices \u2192 Printers & scanners**.  \n  * Find your printer in the list and see if there\u2019s also anything like \u201cScanner settings\u201d under that printer. If you see that, Windows is recognizing its scanner component. ([support.microsoft.com](https://support.microsoft.com/en-gb/windows/install-and-use-a-scanner-in-windows-4fd9f33a-25b6-159a-3cde-3f009b02a81a?utm_source=openai))  \n  * If you don\u2019t see it listed as a scanner, identification at the OS level is failing. ([support.microsoft.com](https://support.microsoft.com/en-gb/windows/install-and-use-a-scanner-in-windows-4fd9f33a-25b6-159a-3cde-3f009b02a81a?utm_source=openai))  \n\n- Open **Device Manager** and check under:\n  * *Imaging devices*\n  * *Printers*\n  * *Other devices*\n\n  If the scanner shows with a yellow error icon, or appears as an \u201cUnknown device\u201d or \u201cUSB Imaging Device\u201d under \u201cOther devices\u201d, driver issues are likely. ([techyorker.com](https://techyorker.com/how-to-fix-hp-scanner-not-working-in-windows-11/?utm_source=openai))\n\n---\n\n## \ud83d\udee0\ufe0f 2. Check Critical Windows Services\n\nSome Windows services must be running for scanning to work.\n\n- Press Windows key + R \u2192 type `services.msc` \u2192 Enter.  \n  * Find **Windows Image Acquisition (WIA)** \u2014 its *Startup Type* should be **Automatic** and status **Running**. Otherwise start it. ([support.hp.com](https://support.hp.com/us-en/document/ish_2041634-1713099-16?utm_source=openai))  \n  * Check dependent services like *RPC (Remote Procedure Call)*, *Shell Hardware Detection*, *DCOM Server Process Launcher*, *RPC Endpoint Mapper*. If those are disabled, scanning might fail. ([support.hp.com](https://support.hp.com/us-en/document/ish_2041634-1713099-16?utm_source=openai))\n\n---\n\n## \ud83d\udce6 3. Install or Reinstall the Correct Full-Feature Driver\n\nIf Windows installed a generic or print-only driver, scanning might not work.\n\n- Get the **Full Software Solution / universal driver** from HP for the M28w. It includes both printing & scanning components. ([support.hp.com](https://support.hp.com/us-en/drivers/hp-laserjet-pro-mfp-m28-family/model/16647051?sku=W2G55A&utm_source=openai))  \n- Before installing, completely uninstall all current HP printer/scanner software & drivers. Then reboot and install fresh using the driver you downloaded. ([support.hp.com](https://support.hp.com/us-en/document/ish_2041634-1713099-16?utm_source=openai))  \n\n---\n\n## \ud83c\udf10 4. Ensure Network/USB Connection is Proper (Based on How You Want to Scan)\n\nSince your printer is wireless, there are two common cases:\n\n- **If using Wi-Fi (network)**: \n  * Make sure your PC and the printer are on the *same Wi-Fi network and subnet*. If they're on different SSIDs (e.g., one on 2.4 GHz, another on guest network, etc.), discovery might fail. ([support.microsoft.com](https://support.microsoft.com/en-gb/windows/install-and-use-a-scanner-in-windows-4fd9f33a-25b6-159a-3cde-3f009b02a81a?utm_source=openai))  \n  * Check the printer\u2019s IP address (via its control panel or by printing a network configuration page). Then try to **ping** that IP from your PC to verify connectivity.  \n\n- **If using USB**:  \n  * Try a different USB port (preferably one directly on the PC, not via a hub).  \n  * Use a known working USB-A/B cable.  \n\n---\n\n## \ud83e\uddf0 5. Use Windows\u2019 Built-in Troubleshooters / Methods\n\n- On the **Printers & scanners** page, select the M28w \u2192 *Remove device*. Then click *Add device or printer again*. Let Windows detect both the printer *and* scanner components. ([support.microsoft.com](https://support.microsoft.com/en-gb/windows/install-and-use-a-scanner-in-windows-4fd9f33a-25b6-159a-3cde-3f009b02a81a?utm_source=openai))  \n- Use **HP Print and Scan Doctor**, HP\u2019s diagnostic tool\u2014it can detect driver/software issues and missing components. ([techyorker.com](https://techyorker.com/how-to-fix-hp-scanner-not-working-in-windows-11/?utm_source=openai))  \n\n---\n\n## \u26a0\ufe0f 6. Check Firewall / Antivirus / App Permissions\n\nSometimes security software or privacy settings block scanners.\n\n- In **Windows Security** or your antivirus, verify that HP Scan (or \u201cHP Smart\u201d, or whatever scanning app you use) is allowed network access.  \n- Go to **Settings \u2192 Privacy & security \u2192 App permissions \u2192 Other devices** (or similar) \u2014 make sure apps are allowed to access devices used for scanning.  \n\n---\n\n## \u2705 Recap: What to Try First\n\n1. Confirm the scanner shows under *Printers & scanners* as having \u201cScanner settings\u201d or similar.  \n2. Check Device Manager to see if the scanner is recognized or has an error.  \n3. Make sure the WIA and other related Windows services are enabled and running.  \n4. Remove any old HP drivers/software, then install the **full driver package** for M28w from HP.  \n5. Ensure PC and printer are on the same network (if using Wi-Fi); or test via USB.  \n6. Run HP\u2019s diagnostic tool and check firewall/permissions.\n\nIf you want, I can walk you through each of these, or help you start with whichever seems most likely in your case \u2014 for example, checking in Device Manager with you. Do you want to try that?"

        "content": "If you can scan via **HP Smart** but not using **HP Scan**, that suggests the scanner hardware is fine and connected over the network; the issue lies with how HP Scan (the more traditional scanning utility) is configured or working. Here are targeted fixes to resolve \u201cscanner not detected\u201d in HP Scan, along with why each step matters.  \n\n---\n\n## \ud83e\uddd0 What\u2019s likely going on\n\nHP Smart works, which means:\n\n- The printer/scanner communicates over Wi-Fi just fine.  \n- The basic scanning driver stack (like WIA/TWAIN) is probably installed.  \n- The OS recognizes \u201csomething\u201d when scanning is requested.\n\nBut HP Scan is not detecting it. This usually points to:\n\n- Driver or software components specific to HP Scan not installed or corrupted.  \n- Required Windows scanning services (like WIA) being disabled or misconfigured.  \n- Firewall or permissions blocking HP Scan\u2019s access.  \n\n---\n\n## \ud83d\udd27 Step-by-step fixes\n\nHere\u2019s how to try resolving the issue:\n\n1. **Verify WIA service & related Windows services**\n\n   - Open Services (`Win + R` \u2192 `services.msc`).  \n   - Scroll down to **Windows Image Acquisition (WIA)**. Ensure its *Startup Type* is **Automatic** and that it is *Running*. ([support.hp.com](https://support.hp.com/us-en/document/ish_2041634-1713099-16?utm_source=openai))  \n   - Also check that *Shell Hardware Detection*, *Remote Procedure Call (RPC)*, *RPC Endpoint Mapper*, and *DCOM Server Process Launcher* are set to Automatic and are running, since WIA depends on them. ([support.hp.com](https://support.hp.com/us-en/document/ish_2041634-1713099-16?utm_source=openai))  \n\n2. **Make sure the full-feature driver / full software package is installed**\n\n   - Windows often installs a print-only or basic driver by default, which may omit the scanner components needed by HP Scan.  \n   - Uninstall current HP printer/scanner driver(s) via *Settings \u2192 Apps* or *Control Panel \u2192 Programs and Features*. Then reboot.  \n   - Go to HP\u2019s website for your printer model and download the \u201cFull Software and Drivers\u201d or \u201cFull Feature Software\u201d package. Install that. ([h30434.www3.hp.com](https://h30434.www3.hp.com/t5/Scanning-Faxing-Copying/Scan-is-not-working-in-hp-smart-app-on-windows-11/td-p/9106861?utm_source=openai))  \n\n3. **Check Device Manager & the Printers & Scanners list**\n\n   - In Windows **Settings \u2192 Bluetooth & Devices \u2192 Printers & Scanners**, find your device. Is there anything like *Scan Options*, *Scanner Actions*, or *Manage Scan to Computer*? If not, detection is incomplete. ([support.hp.com](https://support.hp.com/us-en/document/ish_2041634-1713099-16?utm_source=openai))  \n   - In **Device Manager**, see if the scanner component appears under *Imaging Devices* or *Other Devices*. If it has a warning icon (yellow exclamation), right-click \u2192 *Update Driver*. If it\u2019s missing altogether, installation of the full driver/software (step 2) should help. ([techyorker.com](https://techyorker.com/how-to-fix-hp-scanner-not-working-in-windows-11/?utm_source=openai))  \n\n4. **Firewall, antivirus & app permissions**\n\n   - Open *Windows Security \u2192 Firewall & Network Protection \u2192 Allow an app through firewall*. Confirm that **HP Scan** is allowed for your network profile (Private / Home). If not, allow it. ([h30434.www3.hp.com](https://h30434.www3.hp.com/t5/Printer-Wireless-Networking-Internet/Printer-works-but-scanner-doesn-t/td-p/9366405?utm_source=openai))  \n   - If you have third-party antivirus or firewall software, try temporarily disabling it to see if that lets HP Scan detect your scanner. Sometimes security software blocks the ports or shared network calls that scanning requires. ([h30434.www3.hp.com](https://h30434.www3.hp.com/t5/Scanning-Faxing-Copying/Scanner-was-working-and-not-working-anymore/td-p/9590308?utm_source=openai))  \n\n5. **Network setup**\n\n   - Double-check that your computer and printer are on *exactly* the same Wi-Fi network/subnet (for example, both on 2.4 GHz, or both on 5 GHz, not one on a guest or isolated network). Sometimes means vs. difference in SSID names or bands. ([whizz-print.com](https://whizz-print.com/guides/hp-scan-software-not-opening-2/?utm_source=openai))  \n   - If the printer has a fixed IP, try pinging it from your computer to confirm basic connectivity: open Command Prompt \u2192 `ping <printer-IP>`. If it fails, HP Scan may fail to discover the scanner over the network.  \n\n6. **Use alternative scanning utilities to test**\n\n   - Try *Windows Fax and Scan* or the *Scan* app preinstalled in Windows. If those detect the scanner, it indicates the hardware and drivers are fine and the issue is specific to HP Scan. ([support.hp.com](https://support.hp.com/us-en/document/ish_2041634-1713099-16?utm_source=openai))  \n   - Run **HP Print and Scan Doctor**, HP\u2019s diagnostic tool, which can detect and fix many common driver or connection issues. ([drivereasy.com](https://www.drivereasy.com/knowledge/fixed-hp-scanner-not-working-issues/?utm_source=openai))  \n\n7. **Check or reset the HP Scan software**\n\n   - Sometimes applications themselves become corrupted after updates. You can try repairing or reinstalling HP Scan.  \n   - If available, use *Settings \u2192 Apps \u2192 HP Scan \u2192 Advanced options* \u2192 *Repair* or *Reset*. If no repair/reset option, uninstall the HP Scan software, reboot, then install fresh from the official HP download for your model.  \n\n---\n\nIf you like, I can walk you through one of these steps (e.g. checking Device Manager or reinstalling the driver) with specific instructions for your M28w. Do you want to try starting with one particular step?"
