Solutions

Quick Diagnosis

If the device disconnects during heavy batch scanning, the USB connection is likely suffering from insufficient power or signal interference.

Step-by-Step Solution

  1. Disconnect the USB cable from both the PC and the scanner.
  2. Close the HP Scan software and any related processes.
  3. Connect the scanner directly to a rear USB 3.0 port on your computer.
  4. Ensure the driver is visible in the Device Manager without errors.

Prevention and Maintenance

Always use direct connections instead of USB hubs, as scanners need stable voltage. Cleaning the rollers regularly keeps the scanner moving smoothly without putting unnecessary stress on the feed motor.

When to Call a Technician

If the error persists after testing with a new cable and different computer, the scanner's internal communication port may be faulty.
