3.1. Connect the Scanner to Your Mac

First, prepare a Mac-compatible scanner or an all-in-one printer with scanning capabilities.

Depending on the device's supported connection options, connect the scanner to your Mac using a USB cable or Wi-Fi. If your Mac has a USB-C port but your scanner uses a different cable connection, you may need an adapter.

Once connected, turn on the scanner and check whether your Mac recognizes the device:

  1. Click the Apple menu and open System Settings.

  2. Select Printers & Scanners.

  3. Check whether your scanner appears in the device list.

  4. If it does not appear, click Add Printer, Scanner, or Fax, then select and add your device.

If your Mac cannot recognize the scanner, check the USB cable or Wi-Fi connection. You can also visit the manufacturer's website to download drivers and software compatible with your current macOS version.

3.2. Place the Documents in the Scanner

Open the scanner lid and place the document face down on the scanner glass, aligning it with the positioning marks on the device. Then close the lid to prevent external light from affecting the scan quality.

If your scanner has an Automatic Document Feeder (ADF), you can also load multiple pages into the feeder. Follow the paper orientation markings on the device to ensure the pages are positioned correctly.

Before scanning, make sure the paper is flat and properly aligned. This helps prevent skewed pages, cropped content, or incomplete scans.

3.3 Scan Documents Using Image Capture

Image Capture is a built-in macOS application that lets you access a connected scanner, adjust scanning settings, and save scanned files to a specific location on your Mac.

Best for: Basic document and photo scanning without installing additional scanning applications.

  1. Search for and open Image Capture using Spotlight.

  2. Select your connected scanner from the device list on the left.

  3. Choose Flatbed or Document Feeder, depending on your scanner type. If your device supports it, you may also be able to select double-sided scanning.

  4. Click Show Details to expand the available scanning options.

  5. Adjust the scanning settings as needed, including color mode, resolution, paper size, file format, and save location.

  6. Click Overview to preview the scan and adjust the scanning area if necessary.

  7. Click Scan to start scanning. Once the process is complete, locate the saved file in Finder and check that all pages are complete and the text is clear.

If you use an automatic document feeder, you may be able to scan multiple pages continuously, depending on your scanner's capabilities. Some macOS scanning interfaces also support combining multiple scanned pages into a single PDF file.

Things to Keep in Mind

  • The available options in Image Capture depend on your scanner model and its drivers. Not all devices support automatic document feeding or double-sided scanning.

  • In some macOS versions, selecting PDF as the file format may reveal an OCR (Optical Character Recognition) option that converts scanned content into editable text.

  • If your scanner does not appear, first check whether it has been added under Printers & Scanners in System Settings.

3.4. Scan Documents Using Preview

Best for: Scanning documents that need to be viewed, cropped, rotated, or annotated afterward.

Preview is another built-in macOS application. In addition to opening PDF and image files, it can also access a connected scanner to scan documents. Once scanning is complete, you can view and edit the files within the same application.

Steps to Scan Documents Using Preview

  1. Open Preview on your Mac.

  2. In the menu bar, click File > Import from Scanner, then select your scanner.

  1. Wait for the scanning preview window to appear. If your scanner is not listed, check whether it has been added in System Settings.

  2. Click Show Details if you need access to additional scanning options.

  3. Adjust the scanning settings as needed, including color mode, resolution, paper size, file format, and save location.

  4. Click Scan. Once the scan is complete, the scanned page will open in Preview.

  5. Use the rotate and crop tools to correct the page orientation and remove unwanted edges. To add annotations, open the Markup toolbar and insert text boxes, shapes, or other markings.

  6. Select File > Save to save your changes, or choose File > Export to save the file in another format.

Things to Keep in Mind

  • The scanning options available in Preview vary depending on your scanner model and macOS version.

  • Text and annotations added through the Markup tools are overlays on the original page. They do not directly modify the original text within the scanned image.

  • Preview does not completely lack OCR support. In some configurations, the macOS scanning interface offers an OCR option when PDF is selected as the file format, allowing scanned text to be converted into editable content. The availability of this option depends on your system and scanning device.

3.5. Scan a Document Using Your Scanner’s Software or a Third-Party App

If Image Capture and Preview don't meet your needs, try your scanner manufacturer's software or a third-party scanning application. These tools may offer additional features such as batch scanning, OCR, PDF editing, and file compression.

Use Scanner Manufacturer Software

Some manufacturers, such as CZUR, offer dedicated scanning software for Mac.

  1. Visit the manufacturer's official website.

  2. Download and install the software compatible with your scanner model and macOS version.

  3. Connect the CZUR scanner to your computer and open the software.

  4. Adjust the scanning settings, such as resolution, color mode, file format, and save location.

  5. Start scanning and check the scanned document 

  6. saved files.

Use Third-Party Scanning Applications

Third-party apps may provide additional features, including:

  • OCR: Convert scanned text into searchable or editable content.

  • PDF Editing: Merge, split, rotate, and rearrange pages.

  • Batch Processing: Scan or process multiple pages at once.

  • File Compression: Reduce file sizes for easier storage and sharing.

Before installing an app, check its compatibility with your scanner and macOS version, pricing, and privacy policy. Some applications only edit existing scanned files rather than connect directly to a scanner, so confirm that they support the functions you need.

3.6. Scan With an iPhone or iPad Using Continuity Camera

If you don't have a scanner available, you can also use Continuity Camera on your Mac to scan paper documents with an iPhone or iPad and transfer the scanned files directly to your Mac.

Check Device Compatibility

Before getting started, make sure that:

  • Both your Mac and iPhone or iPad support Continuity Camera.

  • Wi-Fi and Bluetooth are enabled on both devices.

  • Both devices are signed in to the same Apple Account.

  • The devices are near each other and meet Apple's hardware and software requirements.

Scan Documents Using Continuity Camera

  1. On your Mac, open an application that supports Continuity Camera, such as Notes, Pages, or Mail.

  2. Place the cursor where you want to insert the scanned document.

  3. Right-click at that location or Control-click.

  4. Select Insert from iPhone or iPad > Scan Documents.

  5. The camera interface will open on your iPhone or iPad. Position the document within the camera's view. Your device will usually detect the page edges automatically and capture the document.

  6. If you prefer to capture the document manually, tap the shutter button, adjust the page edges, and select Keep Scan.

  7. If you have multiple pages, continue scanning the remaining documents. Once finished, tap Save.

The scanned documents will be transferred automatically to your Mac and inserted at the location you selected. If you start scanning from Finder or the desktop, the scanned document will be saved as a separate file instead.

Things to Keep in Mind

  • Continuity Camera does not require a separate scanner, but it does require compatible Apple devices.

  • Before scanning, make sure the document is in a well-lit area to avoid shadows and glare that could affect image recognition.

  • This method is suitable for occasional scanning and small document batches. If you regularly scan large volumes of documents, a dedicated scanner is generally more convenient.

  • Documents scanned using Continuity Camera are not automatically saved to your iPhone or iPad. Instead, they are transferred to the selected location on your Mac.

4. Common Mac Scanning Problems and Fixes

Try these fixes before changing settings or reinstalling anything. Most of the time, it’s just a missed setting.

Problem

Likely Cause

What to Do

Scanner Undetected

A loose connection or a scanner macOS doesn’t work with.

Check the scanner’s power and connection, and confirm macOS supports it. Add it again in System Settings > Printers & Scanners.

Missing Or Failing Scan Option

The app doesn’t work with the scanner, or the scan area is wrong.

Reset the scan area, or switch to a built-in app.

Bad Image

Dirty glass or a crooked page.

Wipe the glass and straighten the page. Rescan at 300 dpi or higher.

No Saved File Or Wrong Format

Wrong save settings.

Look in the folder you picked for the scan. Export a PDF from Preview.

Wireless Scanning Not Working

A weak or unstable network.

Restart the router and devices. Switch to a USB cable instead.

Process Still Fails

A problem with the scanner or its software.

Check the scanner’s manual and contact the maker’s support.

5. FAQs About Scanning on a Mac

That’s all for how to scan on Mac. The answers below will cover the questions that might come up once you start scanning.

How do I write on a document I scanned?

Use Preview. You can write on top of a scan there, including signatures. To change the words already on the page, you’ll need OCR and an editor that can view the text.

Where does the picture get saved on my Mac when I scan it?

Normally, it’s in the folder set by the scanning app, though sometimes it’s added to an open document. If you can’t see it, search on Finder by filename.

What do I do if I follow all the steps, but nothing happens?

A weak connection or an unsupported app can stop a scan, and so can wrong settings. The troubleshooting section above has fixes.

What file format should I use for a scanned document?

PDF is what to use for paperwork. It keeps all the pages in one file. In case of screenshots or graphics that need to stay sharp, PNG is more effective. JPG is also usable for visuals and normal photos, but is only recommended if your intent is just to quickly share the files.

Do you need a dedicated document scanner?

Not if your all-in-one printer can scan or you have a compatible iPhone or iPad with Continuity Camera. A dedicated scanner makes sense if you scan a lot, especially with an automatic document feeder.
