Here's why:
* Scanners require processing power: Scanners themselves don't have the ability to process and save data independently. They need a computer or a device with processing power to handle the image data.
* USB drives are storage only: USB drives are primarily for storing data, not processing it. They act as a storage space for files.
How to save scans onto a USB drive:
1. Connect scanner to computer: Connect your scanner to the computer via USB cable or wirelessly.
2. Scan document: Use the scanner software to scan your document.
3. Save scan to computer: Choose a location on your computer to save the scanned document as an image file (e.g., JPEG, TIFF).
4. Transfer to USB drive: Copy the saved scan file from your computer to the USB drive.
Alternative solution (with limitations):
Some newer scanners offer features like:
* Direct USB printing: You can print the scan directly to a USB-connected printer, but this doesn't save the scan itself.
* SD card slot: Some scanners may have an SD card slot, allowing you to save scans directly onto the card. However, this is often limited to specific file types and formats.
In summary, you need a computer or a dedicated scanning device with processing capabilities to save scans directly onto a USB drive.
