Prerequisites and Hardware Checks
Before changing software settings or reinstalling drivers, verify that the physical scanner hardware and its Windows connection are ready to capture an image:
- Confirm the printer has a scanner assembly: Single-function printers do not scan. Look for a liftable top lid covering a flatbed glass pane, an automatic document feeder (ADF) input tray on top, or model branding such as All-in-One, MFP, or MFC.
- Check for protective shipping locks or film: On a new or recently moved flatbed scanner, check underneath or along the rear edge of the scanner unit for a physical carriage lock switch and set it to the unlocked icon. If the carriage is locked or a protective plastic strip covers the narrow ADF calibration glass, the sensor cannot read the page.
- Verify the Windows Scan app is installed: Windows includes the legacy Windows Fax and Scan desktop tool, while Microsoft distributes the modern Windows Scan app (listed simply as Scan after installation) free through the Microsoft Store.
- Run a standalone hardware copy test: If your scanner is an all-in-one printer with a physical Copy button on its control panel, place a printed page face down on the flatbed glass and press Copy. If the printed copy comes out blank without involving the PC, the issue is on the device itself (such as paper orientation, an open lid, a dirty ADF sensor strip, or a failed CIS/CCD lamp) rather than in Windows.
Step-by-Step: Fix Orientation and Source Settings in Windows Scan
In the majority of blank-scan cases, the scanner is working normally, but it is scanning the wrong surface or the blank back side of the sheet. Leaving Source set to Auto-configured in Windows Scan frequently causes the app to default to the empty flatbed glass even when pages are loaded in the top feeder.
1. Load the Document with the Correct Orientation
Paper orientation rules differ between the flatbed glass and the document feeder, and feeder orientation varies even across models from the same brand.
- For the flatbed glass: Lift the scanner cover and place the document face down on the glass, aligning the top-left corner of the page with the physical corner arrow or registration mark molded into the bezel. Close the lid completely so ambient room light does not wash out the sensor.
- For the automatic document feeder (ADF): Check the small engraved or printed page icon inside the feeder tray.
- On most flatbed all-in-one printers from HP, Canon, and Epson, the feeder pulls from the top of the stack and scans the top surface, meaning pages must be loaded face up.
- On many dedicated sheet-fed scanners (such as Epson DS models and Brother ADS models), the sensor sits underneath the paper path, requiring pages to be loaded face down.
- Slide the adjustable paper-width guides until they rest lightly against the edges of the stack. Ensure the leading edge of the paper triggers the feeder's mechanical paper-present lever; when recognized, many printers beep or illuminate a feeder status light on their control panel.
2. Manually Select the Source and Test a Preview in Windows Scan
Do not rely on automatic source detection when troubleshooting blank output. Explicitly bind the app to the tray you loaded.
- Right-click the Start button, select Search, type
Windows Scan, and select Scan under Apps. (If it is not installed, open the Microsoft Store, search for Windows Scan, and select Get or Install.) - In the Scanner drop-down menu on the left side of the Scan app, select your specific scanner or multifunction printer. If multiple entries appear for the same machine, avoid entries labeled
FaxorWSDif a direct model name is available. - In the File type drop-down menu, select JPEG or PNG for quick test scans.
- Select Show more directly below the main drop-down menus if the Source menu is not already visible.
- Open the Source drop-down menu and change it from Auto-configured to match your physical setup:
- Select Flatbed if the page is face down on the scanner glass.
- Select Feeder if the page is loaded in the top document feeder tray.
- Test the capture using Preview (when scanning from the flatbed):
- With Source set to Flatbed, select the Preview button at the bottom of the window. The scanner carriage will make a fast pass and display the captured image directly inside the Scan app window.
- Verify that the text or picture is visible inside the preview frame and adjust the circular crop handles at the corners if the selection box is accidentally cropped to a blank margin of the page.
- Note that when Source is set to Feeder, the Preview button is hidden because pulling a sheet through the rollers constitutes a full scan pass.
- Select the Scan button at the bottom of the app to perform the final scan.
Verification of Success
Once the scan finishes, a notification banner appears at the top of the Scan app:
- Select View in the completion banner to open the file immediately in the Windows Photos app, or open File Explorer and browse to
Pictures\Scansinside your user profile folder (the default save path unless changed under Show more > Save file to). - Confirm that the saved image contains your printed content, is right-side up, and has no unexpected blank pages interspersed.
Alternate Method: Compare Results with the Manufacturer's Scanning App or Windows Fax and Scan
If the Windows Scan app continues to output blank files after you manually select Flatbed or Feeder, you need to determine whether the failure is limited to the UWP Scan app, affects the entire Windows Image Acquisition (WIA) subsystem, or stems from a missing TWAIN/vendor driver.
Test 1: Compare with the Legacy Windows Fax and Scan Tool
Windows Fax and Scan talks directly to the local WIA driver and exposes a separate source selector.
- Press Windows key + R, type
wfs, and press Enter to launch Windows Fax and Scan. - Select New Scan on the top toolbar. If prompted, choose your scanner and select OK.
- In the New Scan dialog box, open the Source drop-down menu and select Flatbed or Document Feeder.
- If you selected Flatbed, select Preview and check whether the image renders on the right side of the dialog. Make sure the dashed cropping rectangle encloses the whole page and is not collapsed onto a white corner.
- Select Scan.
Test 2: Compare with the Manufacturer's Scanning Utility
Printer and scanner vendors provide dedicated software that often communicates over the manufacturer's own TWAIN driver or network protocol rather than Microsoft's generic WIA class driver:
- HP: HP Smart (or the HP app / HP Scan from the full software package)
- Epson: Epson Scan 2 or Epson ScanSmart
- Canon: Canon IJ Scan Utility
- Brother: Brother iPrint&Scan or ControlCenter4
Open the manufacturer's application for your device, explicitly set the document source to Flatbed Glass or ADF / Document Feeder, and run a test scan.
- If the manufacturer's app scans properly while Windows Scan produces blank pages: Your hardware and vendor TWAIN driver are healthy, but the WIA driver interface or the Windows Scan app profile is misconfigured. Either use the manufacturer's app for daily scanning or update the WIA driver using the steps below.
- If both the manufacturer's app and Windows Scan produce blank pages from the feeder, but the flatbed works: Check page orientation in the feeder first; if orientation is correct, clean the narrow ADF sensor glass strip (covered in the troubleshooting section).
- If both apps produce blank pages from both sources: Proceed to restarting the WIA service and reinstalling the scanner driver.
Restart the WIA Service and Update the Scanner Driver
When Windows installs a multifunction printer automatically over USB or Wi-Fi, it frequently binds the device to a generic Microsoft IPP Class Driver or WSD (Web Services for Devices) scan driver. If that generic driver stalls or corrupts its image stream, the scanner carriage moves normally, yet Windows receives a zeroed-out (all-white) image buffer.
1. Restart the Windows Image Acquisition (WIA) Service
The Windows Image Acquisition service (StiSvc) manages communication between WIA-compatible scanners and Windows apps.
- Close Windows Scan and any open manufacturer scanning software.
- Press Windows key + R, type
services.msc, and press Enter. - Scroll down the alphabetical list and locate Windows Image Acquisition (WIA).
- Right-click Windows Image Acquisition (WIA) and select Properties.
- Confirm that Startup type is set to Automatic.
- If the Service status shows Running, select Stop, wait five seconds, and then select Start. If it is stopped, select Start.
- Select Apply, then OK, and test a scan again.
2. Reinstall or Update the Full Manufacturer Scanner Driver
Warning: Uninstalling your scanner or multifunction device in Device Manager or Windows Settings temporarily removes its scan (and potentially print) queues until the replacement driver package completes installation. Before removing the device, download the latest full driver and software package for your exact model and Windows architecture (64-bit or ARM64) from the manufacturer's official support page.
Remove the Stale Scanner Entry in Settings
On Windows 11:
- Select Start > Settings > Bluetooth & devices > Printers & scanners.
- Select your scanner or multifunction printer from the list.
- Select Remove at the top of the device page and confirm.
On Windows 10:
- Select Start > Settings > Devices > Printers & scanners.
- Select your scanner or multifunction printer from the list, select Remove device, and confirm.
Clear the Imaging Device Driver in Device Manager
- Right-click the Start button and select Device Manager.
- Expand Imaging devices (and check Printers or Software devices if your scanner is listed there).
- Right-click your scanner entry and select Uninstall device.
- If a checkbox labeled Attempt to remove the driver for this device appears, leave it unchecked first if you only want to refresh the device binding, or check it if you already downloaded the vendor's replacement installer and want to purge a broken third-party driver. Select Uninstall.
- Disconnect the scanner's USB cable (if USB-connected) and restart your PC.
Install the Manufacturer Driver Package
- Run the full driver installer you downloaded from HP, Canon, Epson, Brother, or your scanner vendor. Follow the prompts to connect the USB cable or join the network when instructed by the installer.
- If your manufacturer does not provide a standalone installer and relies on Windows Update drivers:
- Reconnect the scanner and turn it on.
- Open Settings > Bluetooth & devices > Printers & scanners (Windows 11) or Settings > Devices > Printers & scanners (Windows 10) and select Add device (or Add a printer or scanner).
- Then check Settings > Windows Update > Advanced options > Optional updates (Windows 11) or Settings > Update & Security > Windows Update > View optional updates (Windows 10) and install any listed scanner or
Imagingdriver updates for your brand.
Driver Rollback Procedure
If a newly installed driver update caused the blank-page behavior to start on a scanner that previously worked:
- Right-click Start and open Device Manager.
- Expand Imaging devices, right-click your scanner, and select Properties.
- Open the Driver tab and select Roll Back Driver (if available).
- Choose a reason for rolling back, select Yes, and restart the computer.
Troubleshooting Common Failure Modes
Every Second Page in a Multi-Page Scan Is Blank
- Cause: Your scanning software is set to two-sided (Duplex) scanning while your original stack is printed on only one side of each sheet. The scanner reads the front face, then reads the blank back face, creating an alternating pattern of text and blank pages.
- Fix: Open your scanner software settings (such as 2-sided scanning in Brother ControlCenter4, 2-Sided in HP Smart, or Scanning Side in Epson Scan 2) and change the setting to Single-Sided or 1-Sided before scanning one-sided originals.
Flatbed Scans Work, but Feeder Scans Are Blank or Streaked (Even with Correct Orientation)
- Cause: When scanning from the flatbed, the scanner lamp travels across the large glass pane. When scanning from the ADF, the lamp parks beneath a separate, narrow strip of glass on the left side of the flatbed while rollers pull the paper past it. If a piece of corrective tape, a sticky note, paper dust, or a stray scrap of paper covers that narrow ADF glass strip or the white pressure strip above it, the sensor cannot see the document properly.
- Fix: Turn off the printer and unplug the power cord. Lift the scanner lid and inspect the narrow glass strip beside the main flatbed glass, as well as the underside of the ADF mechanism. Spray a small amount of glass cleaner onto a soft, lint-free cloth (never spray liquid directly onto the glass) and wipe both the narrow ADF glass strip and the white backing strip until clean and dry.
Faint or Lightly Printed Pages Disappear Completely from the Output
- Cause: Many manufacturer scanning utilities (including Epson Scan 2, Brother iPrint&Scan, and ScanSnap Home) include an automatic Skip Blank Pages or Blank Page Removal filter. If its sensitivity threshold is set too aggressively, pages containing only a brief signature, a receipt, or faint pencil markings are misclassified as blank and discarded, or washed out when combined with high brightness/bleed-through reduction settings.
- Fix: In the manufacturer's scanning app, open the advanced image or page settings and set Skip Blank Pages (or Blank page removal) to Off, or lower the sensitivity slider, then rescan the document.
Windows Scan Saves a Completely Grey or Washed-Out Page with Dark Edges
- Cause: Either the scanner cover was left raised while scanning a small item, or the contrast/brightness slider in the driver properties has been pushed to the maximum extreme.
- Fix: Close the scanner lid completely over the flatbed glass. In Windows Scan, select Show more and verify that Color mode is set to Color or Grayscale rather than high-threshold Black and white, which can drop light colored ink or low-contrast backgrounds entirely to white.
