Scanner not working

[Trinity3219]

When attempting to scan a document, the process enters a buffering state that does not terminate, preventing the document from being saved.

Hi @Trinity3219,

Welcome to the HP Support Community.
 

Thank you for posting your query. I will be glad to help you.

It’s frustrating when the scan process hangs in “buffering” and never completes, like the printer is stuck mid-thought and unable to finish. Here are approved, step‑by‑step methods to break through that frozen scanning process:

1. Use HP Smart’s Diagnose & Fix

• Open HP Smart on your computer.
• Click the wrench (Diagnose & Fix) icon.
• Follow the on-screen steps to detect and repair scanning issues.

2. Run HP Print and Scan Doctor (Windows only)

• Download it from HP’s official site.
• Launch the tool, select your printer, then click Fix Scanning.
• It’ll automatically address common driver, service or connectivity glitches.

3. Restart the Scanner Engine

• On Windows, press Win + R, type services.msc, and press Enter.
• Find Windows Image Acquisition (WIA) service. 
  • Right-click → Restart.
  • Set its Startup Type to Automatic.

4. Power-Cycle Scanner Hardware

1. Turn off the printer.
2. Unplug the power cord for 10–60 seconds.
3. Plug it back in and power on.
4. Try scanning again.

5. Confirm Connection Stability

• USB: Connect directly to a USB port; avoid hubs or adapters.
• Wi‑Fi: Ensure both devices are on the same network and the connection is stable.

6. Reinstall HP Scan Drivers & Software

• Remove current printer via Settings → Printers & scanners.
• Download and install the full HP driver package (includes scanning software and drivers) from the Official HP® Support. 

I hope this helps.

Take care and have an amazing day!
