If you’ve ever stared at your Canon printer, unsure how to turn a paper document into a digital file, you’re not alone. Learning how to use a Canon scanner can feel confusing, especially with multiple methods, apps, and settings across different models. But once you understand the core workflows, scanning becomes fast, reliable, and essential for home, school, or office use.
This guide covers every way to scan with your Canon device. Whether you’re using a Pixma, Maxify, or MG series, you’ll learn how to scan directly from the printer, via computer, or wirelessly from your smartphone. You’ll also discover how to prepare documents, choose the right software, avoid common errors, and produce clean, professional scans every time.
Prepare Your Documents for Scanning
Align Paper Correctly on the Glass
Place your document face-down on the scanner glass. Match the top-left corner of the paper with the engraved arrow or alignment marker near the corner of the glass. Slide it gently into position so both top edges are flush. This prevents skewed or cropped scans.
Pro Tip: Never force paper into place. Misalignment is the most common cause of partial or distorted scans.
Handle Thick or Bound Materials
For books, notebooks, or bound reports, lift the scanner lid to its full hinge height. Position the open book flat on the glass without pressing down hard. Avoid slamming the lid shut because it can damage spines or crack the glass.
Caution: Do not use heavy objects to flatten pages. Over time, this stresses the scanner mechanism.
Use ADF When Available
Models like the Canon Maxify MB5420 include an Automatic Document Feeder that holds 30 to 50 sheets. Insert pages top-edge first, scanning side up. Never feed stapled, folded, or taped documents because they cause jams.
Note: Most entry-level Canon printers like the TS3420, TR3720, and MG2500 do not have an ADF. You must manually replace pages for multi-page scans.
Scan Without a Computer Using Control Panel Buttons
If you only need a physical copy with no digital file involved, use your printer’s control panel. This method works like a photocopier and is supported on models like the Canon Pixma TS3420, TR3720, and MG7720.
Follow these steps to scan directly:
- Power on the printer and ensure it displays ready status.
- Load paper into the input tray and extend the output tray fully.
- Open the scanner lid and place your document face-down, aligned with the top-left arrow.
- Close the lid gently to prevent glare.
- Press the Black Button for black and white copies or the Green Button for color copies.
- Tap the button repeatedly to set the number of copies.
- Wait 14 to 20 seconds per page for the copy to complete.
Warning: This method creates a printed copy only. No digital file is saved unless you use software-connected methods.
Scan from Windows PC: Three Methods

Scan from iPhone or Android Smartphone
Install the Canon PRINT App
Download Canon PRINT Inkjet/SELPHY from the App Store for iOS or Google Play for Android.
Register Printer to Wi-Fi
- Open the app and tap the printer icon, then select Register Printer.
- Tap Printer not found if prompted.
- Select No when asked about Wi-Fi Direct, then choose Auto Connection.
- On your printer, press and hold the Wi-Fi button (two ovals) for 2 seconds until it blinks.
- In the app, tap Yes, check the box, and tap Next.
- Enter your Wi-Fi password and tap OK, then Connect, then Yes.
- Wait for the green checkmark confirming successful connection.
Critical: Both your phone and printer must be on the same Wi-Fi network.

- For multi-page documents, remove the current page, insert the next one, and tap Scan again.
Result: Pages automatically combine into one PDF file.
Share or Save Your Scan
After tapping Exit, the file saves to your phone storage. Access it through Photos on iPhone or File Manager on Android. Share via email, Google Drive, iCloud, Dropbox, or social media apps.
Best Practice: Clean the glass before scanning. Fingerprints cause dark spots in your scans.
Choose the Right File Format
PDF for Documents
Use PDF for contracts, forms, receipts, or any text-based document. It preserves layout and supports multi-page files. This format is ideal for email or digital filing.
JPEG for Photos
Choose JPEG for images, artwork, or visual content. This format creates smaller files, perfect for sharing online.
TIFF for Archival Quality
Use TIFF when you need lossless quality. This format is ideal for scanning important records or photos you plan to edit. Files are larger, but no compression quality is lost.
PNG for Graphics
PNG supports transparency and high detail. This format works great for diagrams, logos, or web graphics.
Multi-Page PDF Tip: This feature is only enabled in MP Navigator EX, the Canon PRINT app, and macOS Open Scanner with the Combine option.
Connect Your Scanner Properly
Use USB for Stability
USB offers the fastest and most reliable connection. Plug-and-play setup requires no network configuration. This method is ideal for high-volume or high-resolution scans.
Recommendation: Use USB when scanning more than 5 pages or at 600 or higher dpi.
Use Wi-Fi for Convenience
Wi-Fi requires no cables and allows scanning from anywhere on your network. Initial setup is required, and connections can drop during long scans.
Fix Connection Drops: Lower your resolution or switch to USB for critical jobs.
Try Wi-Fi Direct
Wi-Fi Direct connects your phone directly to the printer without a router. This is useful when no Wi-Fi network is available. The pairing is temporary and turns off after use.
Use Case: Scanning while traveling or in temporary workspaces.
Ethernet for Office Models
Ethernet is available on Canon Maxify series printers. This option offers wired network stability for shared office scanning.
Fix Common Scanning Problems
Scanner Not Detected
Causes: Missing drivers, wrong connection, or printer is off or offline.
Solutions: Reinstall the full driver from Canon’s website. Restart both printer and computer. Try USB instead of Wi-Fi. Re-add the printer in your system settings.
Poor Scan Quality
Symptoms: Blurry, dark, or streaked output.
Fixes: Clean the scanner glass with a lint-free cloth and isopropyl alcohol. Increase your resolution to 200 or higher dpi for text. Avoid overhead lighting when scanning glossy paper.
Document Skewed or Cut Off
Re-align your document with the top-left marker. Ensure no paper overhangs the edges. Do not lift the lid during scanning.
Multi-Page PDF Won’t Combine
On Mac, enable the Combine into Single Document option. On mobile, keep all settings identical across scans. On MP Navigator EX, use Batch Scan mode.
App Can’t Connect to Printer
Press and hold the Wi-Fi button for 2 seconds to re-enable pairing mode. Confirm both devices are on the same network. Re-register the printer in the Canon PRINT app.
Optimize Scanning Performance
Clean Scanner Glass Weekly
Wipe the glass with a soft, dry, lint-free cloth. For smudges, lightly dampen the cloth with isopropyl alcohol. Never spray cleaner directly on the glass.
Avoid: Ammonia-based cleaners because they damage the anti-reflective coating.
Set Correct DPI
Use 150 to 200 dpi for standard documents and receipts. Use 300 dpi for archival text, forms, and contracts. Use 600 to 1200 dpi for photos and detailed artwork.
Warning: Higher dpi means larger files and slower scans. Use only when necessary.
Avoid Glossy Paper Glare
Glossy documents reflect light and cause white spots. Reduce overhead lighting or scan in a dimmer room.
Scan in Batches
Use MP Navigator EX or the Canon PRINT app to scan multiple pages into one file. This saves time and keeps documents organized.
Name Files Clearly
Use descriptive names like Invoice_Acme_Jan2025.pdf or Contract_Smith_Signed.pdf. Avoid generic names like Scan001.
Back Up Important Scans
Save copies to cloud services like Google Drive, iCloud, or OneDrive. Also save to an external hard drive or email the file to yourself for safekeeping.
