Canon Pixma TR8620 Not Printing — Here’s the Quick Fix

If your Canon Pixma TR8620 printer suddenly stops printing, keeps showing errors, or doesn’t respond when you try to print, don’t worry — it’s often not a serious problem. Most of the time, your printer is fine, but the software on your computer that helps it “talk” to the printer needs to be updated or repaired.

This issue usually happens when that software (called a printer driver) becomes outdated, missing, or gets damaged after a Windows update or system change. The good news is that this is an easy fix once you know what to do. In this guide, we’ll walk you through simple steps that anyone can follow — no technical background needed.

You’ll also learn about DriverAssist, a trusted tool that can automatically detect and fix issues like this in minutes.

Why Your Canon Pixma TR8620 May Stop Printing

Your Canon printer relies on small helper programs in your computer that make sure everything you send to print is correctly understood. When those programs are outdated or damaged, your computer and printer stop communicating properly.

Here are some signs this might be happening:

• Your printer shows as “offline” even when it’s connected.
• You see messages like “Printer not responding” or “Print job failed.”
• Nothing happens when you click “Print.”
• The printer keeps appearing and disappearing from your list of devices.

In most cases, these problems aren’t with the printer itself. They’re caused by Windows using an outdated or incorrect version of that printer communication software.

If your printer prints successfully, your issue is resolved.

Manual Option 2: Update Using Windows Device Manager

Windows also has a built-in tool that allows you to manually check and install updated software for your printer. This can sometimes fix connection or recognition problems.

Here’s how to do it:

1. Press the Windows key + X on your keyboard and select Device Manager.
2. In the list that appears, find Printers or Print queues.

Try printing a document afterward to see if the issue is resolved.

What If the Printer Still Doesn’t Print?

If you’ve tried the manual steps and your printer still won’t print, it’s possible that:

• The wrong version of the software was installed.
• The Windows update replaced it with a generic version.
• There are leftover files from a previous installation causing conflicts.

In this case, using DriverAssist is the fastest way to clean up the old files and install the correct one automatically. It ensures that your printer gets the exact software it needs without guesswork.
