What the PIXMA TS3722 Can (and Can’t) Do When Scanning
The TS3722’s scan output is typically handled by one of two routes: a desktop scanner utility (Canon’s IJ Scan Utility) or the Canon PRINT app on your phone. In both cases, you choose the scan type (document vs. photo), resolution, and the file type you want saved.

Before You Start: Prerequisites and Best Setup
Most scanning issues come down to connectivity or missing drivers. Get these basics correct first.
- Network: Connect the printer and your device to the same Wi‑Fi network.
- Power: Keep the printer awake during the scan (avoid turning it off mid-process).
- Paper and glass: Clean the scanner glass if you see streaks (use a soft, lint-free cloth).
- Driver/software: Install IJ Scan Utility on the computer (Windows/macOS) and install the Canon PRINT app on mobile.
Method 1 (Most Reliable): Scan to Your Computer with IJ Scan Utility
IJ Scan Utility is the most predictable way to scan and save, because it runs locally and gives you direct control over file type, resolution, and destination settings.
Windows 10/11: Install and Scan with IJ Scan Utility
Use the Canon IJ Scan Utility (often installed with the TS3722 printer driver) to capture a document or photo and save it as PDF/JPEG.
- Connect to the same Wi‑Fi: Ensure the printer and your Windows PC are on the same network.
- Open IJ Scan Utility: Click Start and search for IJ Scan Utility.
- Select your scan mode: In IJ Scan Utility, choose Document for papers or Photo for prints.
- Set the file type: Look for File Format (common choices are PDF and JPEG).
- Pick resolution: Typical settings:
- 300 dpi for readable documents
- 600 dpi for small text or receipts with fine detail
- 150–300 dpi for casual photos
- Choose color: Select Color or Grayscale depending on what you’re scanning.
- Select the destination/save behavior: Use the setting that controls Save to or Destination. If there’s a Settings button, open it and confirm where files go.
- Start the scan: Click Scan.
- Confirm the saved file: Open File Explorer and check the folder you selected (or the default save location shown in IJ Scan Utility).
If IJ Scan Utility doesn’t show the TS3722 scanner, use troubleshooting below (driver, firewall, and Wi‑Fi checks).
macOS 13+ (Ventura/Sonoma): Scan with IJ Scan Utility
On macOS, IJ Scan Utility provides a similar flow: pick scan type, adjust format/resolution, then save to a folder.
- Confirm Wi‑Fi: Put the Mac and the TS3722 on the same Wi‑Fi network.
- Open IJ Scan Utility: Open Finder > Applications > IJ Scan Utility (or use Spotlight search).
- Choose Document or Photo: Select Document for text-heavy pages.
- Set file format: Choose PDF or JPEG from the file format option.
- Set resolution and color mode: Use 300 dpi as a solid default for documents.
- Set save destination: Confirm the folder location shown in the utility settings.
- Scan: Click Scan (or the on-screen equivalent).
- Verify the output: Open the destination folder you selected to confirm the PDF/JPEG is there.
If you use macOS and expect scans to appear immediately, allow the Canon scanning app access to local folders if macOS prompts you.
Method 2: Scan Using the Canon PRINT App (iPhone/iPad or Android)
The Canon PRINT app can scan directly from your TS3722 and save to your phone. This is convenient for receipts, quick documents, and sharing.

- Start scanning: Tap Scan (or the scan icon).
- Select scan type: Choose Document or Photo depending on your content.
- Choose scan quality/file type: Look for a PDF option for documents; choose JPEG if you only need an image.
- Save/export: After scanning, tap Save or Export and select Files (recommended) or Photos.
- Confirm: Open the Files app and check the saved folder.
Android
Android scanning through Canon PRINT follows the same idea: capture via the app, then save via Android storage/share controls.
- Install Canon PRINT: Get the official Canon PRINT app.
- Verify Wi‑Fi: Ensure the printer and your Android phone are on the same network.
- Open Canon PRINT: Launch the app and select PIXMA TS3722.
- Tap Scan: Choose Document for text or Photo for images.
- Pick file type: Select PDF when you need a document; use JPEG for image-only workflows.
- Set quality: If there’s a quality slider, choose a higher setting for small text.
- Save: Tap Save, then confirm the target folder in the Android storage/share prompt.
Choosing the Right File Type: PDF, JPEG, and OCR-Friendly Scans
Picking the right output format affects both readability and file size. Here’s how to choose.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
| When you should use this | Best file type | Typical use case |
|---|---|---|
| Sharing documents, forms, contracts | Emailing, printing later, document archiving | |
| Photos, receipts you’ll edit as images | JPEG | Quick sharing to messaging apps |
| Archiving multi-page documents | PDF (multi-page if supported in your workflow) | Accounting, records, submissions |
| OCR needs (searchable text) | PDF after scan + OCR in your viewer/tool | Use an OCR step after saving if required |
If your goal is “searchable text,” scanning to PDF is only the first step. Most users still run OCR in a PDF viewer or document tool after the file is saved.
Saving Location, File Names, and Reproducible Results
The TS3722 workflow can vary by app, but you want consistent save locations for sanity.
- Computer (IJ Scan Utility): IJ Scan Utility typically offers a Save to or destination setting. Confirm it before you scan.
- Mobile (Canon PRINT): The export/save screen usually controls where the scan lands (Files app folder, Photos album, or a share destination).
- File naming: Default names are often timestamp-based or generic (for example, Scan_0001). If you need predictable naming, rename after saving or use your app’s file naming options if available.
For best repeatability, pick one default output format and one resolution (for example, PDF + 300 dpi for documents) and stick to it.

Troubleshooting: When Scanning Fails or Saves Incorrectly
When scanning doesn’t work, don’t guess—check the failure point. Start with connectivity, then software permissions, then quality settings.
The printer is not detected by the PC app
- Confirm same Wi‑Fi: Printer and PC must be on the same SSID. Guest networks often block device discovery.
- Restart scan software: Close and reopen IJ Scan Utility.
- Reboot devices: Power-cycle the printer, then restart your PC or Mac.
- Update drivers: Re-run Canon’s installer for the TS3722 driver and IJ Scan Utility if you recently changed macOS/Windows versions.
- Firewall/antivirus: Temporarily allow the Canon scanning components in Windows Defender Firewall if discovery is blocked.
The scan starts but the file won’t save
- Check save permissions: On macOS, ensure the scanning app has permission to write to Documents/Downloads.
- Look for an invalid destination folder: If you previously changed the destination in settings, ensure the folder still exists.
- Try a different format: Switching from PDF to JPEG can confirm whether the issue is tied to the chosen output type.
- Free disk space: If your drive is nearly full, scans may fail or be partially written.
Scans are blurry, cropped, or wrong color
- Clean the glass: Smudges and dust cause hazy results and streaks.
- Verify the page placement: Align the document to the guides on the scanner bed.
- Increase dpi for small text: Go from 300 dpi to 600 dpi for fine print.
- Choose the correct mode: Use Document for text and Photo for images. The presets affect sharpening and contrast.
Wi‑Fi drops mid-scan
- Move closer: Wi‑Fi signal drops can interrupt scanning over discovery sessions.
- Switch to computer method: If your phone’s Wi‑Fi is unstable, scanning via IJ Scan Utility may be more stable.
- Use a wired router setup if possible: Routers with stable 2.4 GHz performance usually work best for printers.
Common Mistakes to Avoid
- Scanning at too low resolution: Receipts and small fonts look worse than they need to.
- Saving JPEG when you need a real document: PDFs are better for sharing, archiving, and printing.
- Using different Wi‑Fi networks: Printer discovery fails when you’re on mobile data or a different SSID.
- Skipping destination confirmation: You may end up saving to a folder you can’t find later.
- Forgetting permissions on iOS/macOS: If iOS denies Files access, exports may not show where you expect.
FAQs About Scanning with a PIXMA TS3722
How do I scan multiple pages into one PDF on the TS3722?
Use IJ Scan Utility on your computer if you need the most consistent multi-page PDF behavior. In IJ Scan Utility, look for a multi-page or “Add Page” style option during the scan workflow. On mobile, check whether Canon PRINT offers a multi-page PDF mode in the scan screen.
Why are my scanned PDFs huge?
Most oversized PDFs come from high resolution (for example, 600 dpi) or scanning in full color when grayscale would do. Try 300 dpi and switch color mode to Grayscale for text-only documents.
Can I scan and save without using a computer?
Yes. Use the Canon PRINT app on your iPhone, iPad, or Android phone. You’ll export/save the resulting file to the iOS Files app or Android storage.
My scan is the wrong orientation (rotated). What should I do?
Reposition the page on the glass and rescan. If the app supports rotation correction, apply it after export using a PDF or image editor—but it’s usually better to fix it at scan time.
What’s the best resolution setting for documents?
300 dpi is the practical default for most documents. Use 600 dpi when dealing with small fonts, fine print, or handwriting that must be readable.
Bottom Line
If you want reliable scanning and control over what gets saved, use IJ Scan Utility on your Windows 10/11 PC or macOS. For quick, on-the-go copies, the Canon PRINT app on iPhone/iPad or Android is usually the fastest path.
Pick the right format (PDF for documents, JPEG for images), set a sensible dpi (300 for most pages), and confirm the save destination before starting your scan.
