Why Does My Canon PIXMA TS7720 Keep Saying “Driver Unavailable”?

You sit down to print something important, but your Canon PIXMA TS7720 suddenly refuses to work. Then your computer flashes a message that says “Driver Unavailable.” It’s confusing, and it might sound like something is seriously wrong, but the truth is it’s a common and fixable issue.

This guide will walk you through what this message actually means, why it appears, and the simplest ways to get your Canon PIXMA TS7720 printing again — no technical background required.

What “Driver Unavailable” Really Means

When your printer says “Driver Unavailable,” it’s basically your computer’s way of saying, “I can’t talk to your printer.”

Your computer and your printer communicate through a small piece of software that acts like a translator. If that software is missing, out of date, or damaged, your computer can’t send instructions properly — and your printer stops responding.

You can think of it like trying to send a message in a language the other person doesn’t understand. The connection is still there, but the communication fails.

Here are the most common reasons this happens:

• Your Windows system recently updated and replaced some of your printer’s files.
• The printer’s software didn’t install correctly the first time.
• You moved the printer to a new computer, but the right setup files weren’t installed.
• The printer’s connection was interrupted while it was being set up or used.

Fortunately, fixing it only takes a few simple steps.

Quickest Fix: Let DriverAssist Handle Everything Automatically

The easiest and most reliable way to repair the “Driver Unavailable” message is to use DriverAssist — a trusted tool that automatically finds and installs the correct software for your Canon PIXMA TS7720.

Instead of spending time searching online or guessing what to download, DriverAssist scans your computer and sets up the right files automatically. It only takes a few minutes, and you don’t need to touch any advanced settings.

Follow these steps:

1. Visit the official website.
2. Download and install DriverAssist.
3. Open the program and let it scan your computer.
4. When it detects your Canon PIXMA TS7720, follow the prompts to install the correct software.
5. Restart your computer after installation.

Once your computer restarts, your printer should respond normally again. For most users, this fixes the issue completely.

Manual Fix Option 1: Get the Software Directly from Canon’s Website

If you’d rather not use an automatic tool, you can manually install the correct software from Canon’s official support website. This method ensures you’re downloading files directly from the manufacturer.

Here’s how to do it:

1. Open your preferred web browser and go to the Canon Support site.
2. Type Canon PIXMA TS7720 into the search bar and hit Enter.
3. Choose your printer from the results.
4. On the printer’s page, look for the Drivers & Downloads section.
5. Select your version of Windows (such as Windows 10 or Windows 11).
6. Click Download beside the most recent file available.
7. Once it finishes downloading, open the file and follow the steps that appear on-screen.
8. When the setup is complete, restart your computer and reconnect your printer.

Try printing a page afterward. If the printer responds normally, you’ve successfully fixed the problem.

Manual Fix Option 2: Use Windows Device Manager

Windows also includes a built-in feature called Device Manager, which lets you manually repair or update the software for your printer. It’s a quick fix that can help if your printer software is installed but not working properly.

Here’s how to use it:

1. On your keyboard, press the Windows key + X and choose Device Manager from the list.
2. Find Printers or Print queues and click the small arrow to expand it.
3. Right-click on Canon PIXMA TS7720 and select Update driver.
4. Choose Search automatically for updated driver software.
5. Wait while Windows searches for the correct files and installs them.
6. Restart your computer after the process finishes.

Once your system restarts, open any document and try printing again. If you no longer see the “Driver Unavailable” message, your printer should now be back to normal.

If the Problem Persists

If your Canon PIXMA TS7720 still isn’t responding after trying both methods, some old printer files might be interfering with the new installation. Doing a clean reinstall can often clear things up.

Here’s how to start fresh:

1. Unplug your Canon PIXMA TS7720 from your computer.
2. Open the Control Panel and select Programs and Features.
3. Find any Canon printer software listed and uninstall it.
4. Restart your computer.
5. Reconnect your printer once your computer is back on.
6. Use DriverAssist (recommended) or the Canon website to reinstall the correct software.

A clean reinstall removes old, broken files and helps your system communicate properly with the printer again.

Why You Should Keep Your Printer Software Up to Date

Most people never think about their printer’s software until something goes wrong. But keeping it updated can prevent issues like this from happening in the first place.

When Windows releases updates, small changes in your computer’s system can sometimes break the connection between your printer and your PC. Updating your printer software helps keep both devices in sync.

It also prevents common issues such as:

• The printer disappearing from your list of available devices.
• Print jobs freezing halfway through.
• The printer saying “Not Responding” or “Unavailable.”
• Blank pages or half-printed documents.

By checking for updates every once in a while — or letting DriverAssist handle it automatically — you’ll save time and avoid frustration later on.

Conclusion

A “Driver Unavailable” message can be annoying, especially when you just need to print something quickly. But in reality, it’s simply your computer and printer losing the ability to communicate.

The good news is that the fix is easy. Using DriverAssist is the fastest and most convenient option — it automatically finds and installs the right software for your Canon PIXMA TS7720 without you needing to search for anything.

If you prefer to do things yourself, updating the printer software from Canon’s website or through Windows Device Manager works just as well.

Once the correct software is in place, your Canon PIXMA TS7720 should start printing normally again. In the future, keeping your printer’s software updated will help prevent similar issues from happening.
