The QR code is usually printed on a sticker on the back or bottom of your scanner

Most scanners have a QR code label stuck directly to the device itself. Check the back panel first — that is where manufacturers most often place it. If you do not see it there, look at the bottom of the unit, underneath any rubber feet or protective pads. The code is typically a small square pattern, about the size of a postage stamp, printed in black and white.

If your scanner is mounted in a cabinet or built into a desk, you may need to pull it forward or tilt it to see the bottom clearly. Some older or compact models have the QR code on the side panel instead. Take a moment to rotate the scanner and inspect all surfaces before assuming the code is missing.

Key Takeaways

  • The QR code is a physical sticker on your scanner, most commonly on the back or bottom of the device.
  • You can photograph the code directly with your phone camera or a dedicated QR code reader app.
  • If the sticker is damaged or missing, check your scanner's manual or the manufacturer's website for an alternative code or serial number.
  • The QR code links to setup information, driver downloads, or registration pages specific to your scanner model.

How to photograph the QR code correctly

Once you locate the sticker, use your phone's camera app to take a clear photo. Hold your phone steady about 6 to 8 inches away from the code, making sure the entire square pattern is visible in the frame. The code does not need to fill the entire screen — it just needs to be readable.

Make sure the lighting is good enough that you can see the black lines clearly against the white background. Avoid shadows or glare from overhead lights. If your phone has autofocus, tap the QR code on the screen to focus before you take the shot. A slightly blurry photo often still works, but a sharp one is more reliable.

What to do if the sticker is damaged or peeling

If the QR code label is worn, faded, or partially peeled off, try photographing it anyway — many QR readers can still decode a damaged code if enough of the pattern remains visible. Position your phone at different angles to see if one angle captures the readable parts better than another.

If the code is completely illegible, look for your scanner's model number on the device itself. This is usually printed on a separate label and looks like a string of letters and numbers. You can use the model number to find the same QR code on the manufacturer's website, or to search for the setup information you need directly.

Finding the QR code online if you cannot locate it on the device

Visit the scanner manufacturer's official website and search for your specific model number. Most manufacturers provide downloadable manuals, driver software, and setup guides that include the QR code or a direct link to the same information the code would have opened.

If you have the original packaging or documentation that came with the scanner, check those materials as well. The QR code may also be printed on the quick-start guide, warranty card, or inside the manual cover. Some manufacturers print multiple copies of the code in different places for this reason.

Using the QR code once you have photographed it

Most modern phones automatically recognize a QR code when you open the photo in your camera app or photo gallery. A notification or banner will appear asking if you want to open the link. Tap that notification to go to the page the code connects to.

If your phone does not automatically recognize the code, open a QR code reader app from your phone's app store — these are free and widely available. Open the app, point your phone's camera at the QR code (or select the photo you already took), and the app will decode it and show you the link or information it contains.

Frequently Asked Questions

Can I use a QR code reader app instead of my phone's camera?

Yes. Free QR code reader apps work just as well as your phone's built-in camera. read one from your app store, open it, and point it at the code or select a photo you have already taken. The result is the same either way.

What if the QR code takes me to a page that will not load?

The link may be outdated or the manufacturer's server may be temporarily down. Try again in a few minutes, or use your scanner's model number to search the manufacturer's website directly. You should be able to find the same driver or setup information through a regular web search.

Is the QR code the same as the serial number?

No. The QR code is a scannable pattern that links to information online. The serial number is a unique identifier printed separately on your scanner. You may need both for warranty registration or support, but they serve different purposes.

Do I need the QR code to set up my scanner?

No. The QR code is a shortcut to setup information and drivers, but you can find everything it links to by searching the manufacturer's website with your model number. The code just saves you a few steps.
