The Basic Steps to Scan a Document

To scan a document from your printer to your computer, place the document face-down on the scanner glass or face-up in the automatic feeder, then use either the buttons on the printer itself or scanning software on your computer to start the scan. The scanned image will save to your computer as a file you can open, edit, or share. Most modern printers have this built-in—you do not need any special equipment beyond what you likely already own.

The exact steps depend on whether your printer has a scanner (called a multifunction or all-in-one printer) and which operating system your computer runs. The process takes about two to five minutes from start to finish, including the time for the scanner to process the image.

Key Takeaways

  • Place your document on the scanner glass or in the automatic feeder, then press the Scan button on the printer or use your computer's scanning software to begin.
  • Most printers save scans to a default folder on your computer, usually called "Scans" or "Documents," which you can change in your printer settings.
  • On Windows, use Windows Fax and Scan or your printer's own software; on Mac, use Image Capture or your printer's software.
  • Scanning quality depends on the resolution setting—300 DPI works for most documents, but 600 DPI is better for text you plan to read closely.
  • If your computer does not recognize your printer, install the driver software from the manufacturer's website before you try to scan.

Check That Your Printer Has a Scanner

Not all printers can scan. A printer that only prints is called a single-function printer. A printer that prints, copies, scans, and sometimes faxes is called a multifunction printer or all-in-one printer. Look at the top of your printer—if it has a flat glass panel or a slot where you can feed paper in, it has a scanner. If it only has a paper tray at the bottom, it cannot scan.

Check your printer's manual or the manufacturer's website if you are unsure. Search for your printer model number (usually on a sticker on the back or bottom) plus the word "scanner" to confirm it has scanning capability.

Prepare Your Document and Place It on the Scanner

Before scanning, make sure your document is clean and free of staples, paper clips, or tape. Dust or debris on the glass can create dark streaks on your scanned image. If your document is wrinkled, smooth it out gently with your hand.

Open the scanner lid or access panel. Place your document face-down on the glass, with the corner aligned to the corner marked on the scanner bed (usually the top-left). If your printer has an automatic document feeder (a slot at the top where you stack pages), place your document face-up in that slot instead. The feeder will pull the pages through one at a time, which is faster for multi-page documents but works only with single sheets—not books or thick items.

Scan Using Your Printer's Buttons or Your Computer

You have two ways to start a scan: press the Scan button on the printer itself, or use software on your computer. The printer button is faster for a single document. Look for a button labeled "Scan," "Copy," or with a scanner icon on the printer's control panel. Press it, and the printer will scan the document and send it to your computer automatically.

If you want more control over where the file saves or what quality it scans at, use your computer instead. On Windows, open Windows Fax and Scan (search for it in the Start menu) or your printer's own software, usually found in your Programs menu or installed when you set up the printer. On Mac, open Image Capture (in Applications > Utilities) or your printer's software. Select your printer from the list, place your document on the scanner, and click the Scan button in the software. The scanned image will appear on your screen, and you can save it to a folder of your choice.

Choose Your Scan Settings

Before you scan, check the resolution and file format settings. Resolution is measured in DPI (dots per inch) and controls how sharp the scanned image looks. For everyday documents like receipts, bills, or letters you just need to read, 300 DPI is fine and creates a smaller file. For documents with small text or images you want to read closely, use 600 DPI. For photos, 600 DPI or higher gives better detail. Higher DPI means larger file sizes and longer scan times.

File format is the type of file your scan becomes. PDF is the most common choice because it preserves the layout and works on any computer. JPEG is smaller and good for photos. TIFF is used for archiving because it does not compress the image. Choose PDF unless you have a specific reason to use something else.

Most scanning software lets you preview the scan before you save it, so you can check that the document is straight and fully visible on the page. If it is not, cancel the scan, adjust the document position, and try again.

Find and Organize Your Scanned Files

When you scan using the printer's button, the file usually goes to a default folder on your computer. On Windows, this is often a folder called "Scans" in your Documents. On Mac, it typically goes to a folder called "Scanned Documents" in your Documents. Check your printer's manual or settings to see where your scans are being saved, and change the location if you prefer a different folder.

If you scanned using your computer's software, you chose the save location yourself, so you know where to find the file. Open your file manager (File Explorer on Windows, Finder on Mac) and navigate to that folder. You can rename the file, move it to another folder, or open it in a program like Word or Adobe Reader to view or edit it.

Troubleshoot Common Scanning Problems

If your computer does not recognize your printer, the scanner driver may not be installed. A driver is software that lets your computer talk to your printer. Go to the printer manufacturer's website, search for your printer model, and read the driver for your operating system. Run the installer and restart your computer. Then try scanning again.

If the scanned image is too dark, too light, or has streaks, clean the scanner glass with a soft, dry cloth and try again. If the image is blurry, make sure the document is lying flat on the glass and not wrinkled. If the scan is cut off at the edges, move the document slightly away from the edge of the glass and rescan.

If the automatic feeder is jamming or skipping pages, remove the stack of documents, fan the pages to separate them, and reload them into the feeder. Make sure the pages are all the same size and weight—mixing different paper types can cause jams.

Frequently Asked Questions

Can I scan multiple pages at once?

If your printer has an automatic document feeder, you can load multiple pages and they will scan one at a time into a single file or separate files, depending on your settings. If you are using the glass, you must scan one page at a time. Some scanning software can combine multiple single-page scans into one PDF file after you finish.

What is the difference between scanning and copying?

Copying prints the document directly from the scanner to your printer without saving it to your computer. Scanning saves the image to your computer as a file. If you want to keep a digital copy, scan. If you just need a paper copy, copy.

Can I scan a photo or a book?

Yes, you can scan photos and book pages on the glass, but not in the automatic feeder. Place the photo or open book face-down on the glass, close the lid gently, and scan. For thick books, be careful not to force the lid down, as this can damage the binding.

Why is my scanned file so large?

Large files usually result from high DPI settings or color scanning. If file size matters, lower the DPI to 300, scan in black and white instead of color, or save as JPEG instead of PDF. You can also compress a PDF after scanning using free online tools.

Do I need special software to scan, or can I use what came with my printer?

The software that came with your printer works fine for most scanning tasks. Windows Fax and Scan and Mac's Image Capture are also built-in and free. You only need third-party software like Adobe Acrobat if you want advanced features like editing, combining multiple files, or optical character recognition (OCR).
