3. For WiFi scanning, confirm both devices are on the same network.
4. Restart the printer and Windows computer.

Why Is My HP OfficeJet Pro 8139e Scanner Not Working?

The HP OfficeJet Pro 8139e uses software to communicate with Windows. This software allows the operating system to recognize the printer and scanner and send instructions to the correct device.

When the software is missing, outdated, or damaged, Windows may recognize the printer for printing but fail to communicate with the scanner. You might see messages such as scanner not found, unable to communicate with scanner, or no scanning device detected.

A Windows update can sometimes cause similar problems. System updates may change components that scanning software depends on, which can affect an existing printer and scanner installation.

Connection problems are another common cause. A WiFi interruption, changed router settings, or different network can prevent Windows from finding the scanner even though the printer itself is powered on.

Method 1: Use DriverAssist to Check for Outdated Software

DriverAssist is a convenient first option when the HP OfficeJet Pro 8139e scanner is not being detected correctly. It can scan your Windows computer and identify printer software that may need attention.

Download DriverAssist from the official download page:

Download DriverAssist

Follow these steps:

1. Download and install DriverAssist on your Windows computer.
2. Open DriverAssist after installation.
3. Allow the application to scan your system.
4. Look for the HP OfficeJet Pro 8139e in the detected devices.
5. Review any available software updates.
6. Follow the instructions to install the required update.
7. Restart Windows after the installation is complete.
8. Turn the HP OfficeJet Pro 8139e off and back on.
9. Open your scanning application and try scanning again.

Updating the required software can help Windows communicate with the scanner correctly. This is particularly useful when scanning stopped working after a Windows update or when the printer was recently reinstalled.

An update cannot fix every scanner problem. If the scanner still does not work, continue with the connection and Windows checks below.

Method 2: Get the Correct Software From the Manufacturer Website

You can manually install the appropriate software from the manufacturer's official support website. This option is useful if you want to select the software yourself.

Start by searching for the exact HP OfficeJet Pro 8139e model. Make sure you select the correct model rather than another OfficeJet Pro printer with a similar name.

Find the software or download section on the product support page. You may be asked to choose your operating system.

Select the Windows version installed on your computer. Choose Windows 11 if you use Windows 11, or Windows 10 if that is your current system.

Look for the recommended software package that supports scanning. Download the package and open the installation file.

Follow the instructions shown by the installer. Allow the installation to finish before restarting Windows.

After restarting, turn the printer off and back on. Open your scanning application and check whether the HP OfficeJet Pro 8139e scanner is now available.

Common mistakes can prevent the installation from solving the problem. Choosing a similar printer model, selecting the wrong Windows version, or installing only a basic printing package may leave scanning unavailable.

Method 3: Check the Scanner Through Windows Device Manager

Windows Device Manager can help determine whether Windows recognizes the scanning hardware. This method is useful when the HP OfficeJet Pro 8139e appears to be connected but scanning applications cannot find it.

Follow these steps:

1. Right click the Windows Start button.
2. Select Device Manager.
3. Look for categories related to imaging devices, printers, or scanners.
4. Expand the appropriate category.
5. Look for the HP OfficeJet Pro 8139e or a related scanner entry.
6. Right click the device.
7. Select Update driver.
8. Allow Windows to search for available software.
9. Follow any instructions displayed by Windows.
10. Restart the computer when finished.

The scanner may appear under a different category depending on how Windows detects the device. A warning icon or unknown device entry can indicate that Windows is having trouble recognizing the hardware.

Device Manager has limitations. Windows may report that the best available software is already installed even when the scanner continues to fail. It may also not locate the specific software needed for all scanner functions.

Check the Scanner Connection

A connection problem can prevent the HP OfficeJet Pro 8139e scanner from appearing in Windows.

For a USB connection, check that the cable is firmly connected to both the printer and computer. Try another USB port if Windows does not detect the device.

For WiFi scanning, confirm that the computer and HP OfficeJet Pro 8139e are connected to the same wireless network. If the router, WiFi password, or network name recently changed, the printer may need to be connected again.

Restart the printer and computer after checking the connection. If the wireless network is unstable, restarting the router can also help.

Check Windows Scanner Settings

Windows includes built in options for managing scanners and connected devices.

On Windows 11, open Settings and select Bluetooth & devices. Select Printers & scanners and look for the HP OfficeJet Pro 8139e.

On Windows 10, open Settings, select Devices, then Printers & scanners.

Select the HP OfficeJet Pro 8139e and check whether Windows recognizes the device correctly. If the printer appears but scanning options are missing, the installed software may not include the required scanner components.

Try Windows Scan

Windows may include the Scan application, depending on your system.

Open the Windows Start menu and search for Scan. If the application is installed, open it and check the available scanner list.

Select the HP OfficeJet Pro 8139e if it appears. Place a document on the scanner and start a basic scan.

If the printer is not listed, Windows may not be communicating correctly with the scanner. Check the connection and installed software before trying again.

Restart the Windows Image Acquisition Service

Windows uses a service called Windows Image Acquisition, also known as WIA, to support many scanning devices.

Press Windows + R on your keyboard. Type services.msc and press Enter.

Find Windows Image Acquisition in the list. Right click the service and select Restart.

After the service restarts, close your scanning application and open it again. Try scanning another document.

This step can help when the scanner was working previously but suddenly stopped responding. It does not replace the need for correct printer software or a working physical connection.

Check Scanner Permissions

Windows may restrict access to devices or applications.

Open Windows Settings and check the privacy or permissions options related to cameras and other devices. Make sure your scanning application is allowed to access the required device features.

The exact settings can differ between Windows 10 and Windows 11. After changing a permission, close and reopen the scanning application before testing again.

Why This Problem Keeps Coming Back

A scanner that repeatedly stops working may have an underlying software or connection problem.

Outdated printer software can cause Windows to lose proper communication with the HP OfficeJet Pro 8139e. A major Windows update can also change system components that affect scanning.

Network changes can create recurring problems for wireless users. A new router, changed WiFi password, or different network can prevent Windows from finding the scanner.

Duplicate printer installations can also create confusion. Windows may have more than one entry for the same printer, causing the scanning application to connect to an old or unavailable installation.

Keeping the correct printer software installed and maintaining a stable connection can help reduce recurring scanner problems.

Keep Printer Software Updated Automatically

Printer software can become outdated as Windows receives new updates. Keeping it current can help Windows maintain communication with the printer and scanner.

DriverAssist can simplify the update process by checking the computer for software that may need attention. This can be useful if you do not want to manually search for the correct software package whenever a scanning problem occurs.

You should also keep Windows 10 or Windows 11 updated. After a major Windows update, test both printing and scanning to make sure the HP OfficeJet Pro 8139e continues working correctly.
