The basic steps for any scanner

To scan a document, place it face-down on the scanner glass or face-up in the automatic feeder, depending on your scanner type. Open the scanning software on your computer — usually called a scanner app, driver software, or something like "Canon Scan" or "HP Scan" depending on your brand. Select your document settings (color, black and white, or grayscale), choose where to save the file, then press the Scan button. The scanner will pull the document through or photograph it against the glass, and the image will appear on your screen within seconds to a minute.

The whole process takes less than five minutes once you know where the buttons are. Most people get stuck not because scanning is hard, but because they do not know which software to open or where their scanned files ended up. The steps below walk you through each part so you know what to expect.

Key Takeaways

  • Place your document in the scanner, open the scanner software on your computer, and press Scan — the file saves automatically to a folder you choose.
  • Flatbed scanners work best for single pages or documents you do not want to feed through a machine; automatic feeders are faster for stacks of pages.
  • Choose black and white for text documents to keep file size small, and color only if you need to preserve images or colored text.
  • Check your scanner's default save location — files often go to a "Scans" folder or your Documents folder, not your Desktop.
  • If you cannot find the scanner software, check your computer's installed programs list or the manufacturer's website for a read.

Preparing your document and scanner

Before you scan, make sure your document is clean and flat. Dust, wrinkles, or bent corners can create blurry spots or dark lines on the scanned image. If your document is folded or creased, flatten it under a heavy book for a few minutes. Remove any sticky notes, tape, or paper clips.

Check which type of scanner you have. A flatbed scanner has a glass plate where you lay the document flat, face-down. An automatic feeder (also called an ADF) is a slot at the top where you stack pages and the machine pulls them through one at a time. Some scanners have both. Flatbed scanners are gentler on delicate documents and work better for single pages or odd sizes. Automatic feeders are faster if you have a stack of pages to scan all at once.

If your document is larger than the scanner glass (like a poster or newspaper), you can scan it in sections and piece the images together later, but that takes extra work. For most household documents — bills, letters, forms, receipts — a standard flatbed or feeder will handle the size.

Opening the scanner software on your computer

Your scanner connects to your computer through a USB cable or your home network (Wi-Fi). When you first plug in a new scanner, your computer usually installs the software automatically. If it does not, you will need to read the driver from the manufacturer's website — search for your scanner model and "driver" or "software".

To open the scanning software, look for an icon on your Desktop or in your Start menu (Windows) or Applications folder (Mac). Common names are "Canon Scan", "HP Scan", "Epson Scan", "Brother ControlCenter", or just "Scanner". If you cannot find it, open your computer's list of installed programs and search for your scanner brand. On Windows, go to Settings > Apps > Apps & Features and scroll through the list. On Mac, open Applications > Utilities and look for anything with your scanner's brand name.

If the software is not installed at all, visit the manufacturer's support page, enter your scanner model number, and read the latest driver. Installation usually takes a few minutes and will add the scanning software to your computer automatically.

Choosing your scan settings

Once the software is open, you will see options for how to scan. The most important choices are color mode and resolution. Color mode determines whether the scan is in color, black and white, or grayscale (shades of gray). Resolution is measured in DPI (dots per inch) and controls how sharp and detailed the scan is.

For most documents you want to keep or send to someone else, use black and white mode if the document is text only — this keeps the file size small and makes text crisp and straightforward to read. Use color mode only if your document has images, colored text, or colored sections you need to preserve. Grayscale is a middle ground that works for documents with photos but no color text.

For resolution, 300 DPI is the standard for documents you might print or read closely. If you are just scanning something to store or email, 200 DPI is fine and creates a smaller file. Do not go below 200 DPI unless you are scanning something you will never need to read closely. Higher than 300 DPI (like 600 DPI) creates very large files and is only necessary if you are scanning old photographs or artwork.

Leave other settings at their defaults unless you have a specific reason to change them. Brightness and contrast adjustments are usually not necessary — the software handles them automatically.

Scanning and saving your document

Place your document in the scanner. For a flatbed, lay it face-down on the glass with the corner aligned to the corner marked on the scanner. For an automatic feeder, stack your pages face-up and insert them into the slot. The scanner will tell you if the document is not positioned correctly.

In the scanning software, look for a button labeled "Scan", "Start", or a green arrow. Click it. The scanner will pull the document through or photograph it against the glass. You will hear it working — this is normal. Within a few seconds to a minute, the scanned image will appear on your screen.

The software will ask you where to save the file and what to name it. By default, it usually saves to a folder called "Scans" or "My Scans" in your Documents folder, or sometimes directly to your Desktop. Choose a location you will remember. Name the file something clear like "Electric Bill January 2024" or "Tax Return 2023" so you can find it later. The software will add a file type automatically — usually PDF or JPG.

If you are scanning multiple pages that should be one document, most scanner software has an option to scan multiple pages and combine them into a single PDF. Look for a button that says "Scan More Pages" or "Add Page" after the first scan is done. Repeat the process for each page, then choose "Finish" or "Save" to combine them all into one file.

Finding your scanned files

After you scan, you need to know where the file went. If you chose the save location yourself, look in that folder. If you used the default location, check your Documents folder first — look for a subfolder called "Scans" or "My Scans". On Windows, you can also search for the file by opening File Explorer, clicking the search box, and typing the filename or a word from it.

On Mac, open Finder, click the search icon in the top right, and type the filename. If you remember roughly when you scanned it, you can search by date — type "modified:today" or "modified:yesterday" to find recent files.

Once you find the file, you can open it with any PDF reader or image viewer. To send it to someone, attach it to an email. To print it, right-click the file and choose "Print". To store it long-term, move it to a folder where you keep important documents.

Troubleshooting common scanning problems

If the scanner does not turn on, check that the USB cable is plugged into both the scanner and the computer, or that the scanner is connected to your Wi-Fi network. Restart the scanner by unplugging it for 10 seconds, then plugging it back in. Restart your computer as well — this fixes most connection problems.

If the scanned image is blurry, the document may not have been placed flat against the glass, or the resolution was set too low. Try scanning again with the document pressed firmly into the corner, and increase the DPI to 300 or higher. If the image has dark lines or spots, clean the scanner glass with a soft, dry cloth — dust and fingerprints show up in scans.

If the scanner software will not open, the driver may not be installed correctly. Unplug the scanner, restart your computer, then plug it back in and wait 30 seconds for the computer to recognize it. If that does not work, read the latest driver from the manufacturer's website and install it. If you still cannot find the software, contact the scanner manufacturer's support line — they can walk you through installation.

If the file is too large to email, convert it to a smaller format. Most scanner software has a "reduce file size" option, or you can use a free online PDF compressor. Search for "PDF compressor" and upload your file — it will shrink the file without losing much quality.

Frequently Asked Questions

What is the difference between scanning to PDF and scanning to JPG?

PDF is better for documents you want to keep or send to someone — it preserves the layout and text stays searchable. JPG is better for photos or images. Most scanner software defaults to PDF, which works for almost everything. Unless you have a specific reason to use JPG, stick with PDF.

Can I scan both sides of a document at once?

No, but many automatic feeders have a "duplex" setting that scans both sides automatically — you load the stack once and the machine flips it over and scans the back. Check your scanner's manual or software to see if this option is available. If your scanner does not have duplex, you will need to scan one side, flip the stack, and scan again.

Why is my scanned document coming out sideways or upside down?

You placed the document in the scanner rotated or upside down. Most scanner software has a rotate button that lets you fix this after scanning. Open the scanned file in the scanner software or a PDF reader, look for a rotate icon (usually arrows in a circle), and click it until the document is right-side up. Save the corrected version.

How do I scan a document that is smaller than the scanner glass?

Place it anywhere on the glass — the scanner will capture the whole glass area, so you will have white space around the document. After scanning, you can crop the image in a photo editor or PDF reader to remove the white space, but this is optional. If you are just storing the document, the white space does not matter.

What should I do with the original document after I scan it?

Keep the original for at least a few weeks until you confirm the scan is clear and readable. For important documents like tax returns, insurance papers, or legal forms, keep the original indefinitely in a safe place. For everyday documents like bills or receipts, you can shred or recycle the original once you have verified the scan is good.
