Why Does Canon Printer Say 'Printer is Busy'?

Canon printers are known for their reliability, performance, and quality prints. However, like any electronic device, they can encounter issues that frustrate users, one of the most common being the “Printer is Busy” error. This problem usually occurs when you are trying to print, scan, or copy, but the printer fails to respond and instead displays the message that it is busy.

Common Causes of the "Printer is Busy" Error

Understanding the root causes of this error is the first step to fixing it. Here are the most common reasons why your Canon printer may say it is busy:

Pending Print Queue
If too many documents are in the queue or if a previous task has not been cleared, the printer may display the busy message.
Driver or Software Conflicts
Outdated or corrupted Canon printer drivers can create communication problems between your computer and the printer.
Network Connectivity Issues
If your Canon printer is connected via Wi-Fi, unstable connections can cause delays and errors.
Hardware Malfunctions
Paper jams, cartridge issues, or sensor malfunctions can stop the printer from working properly.
Background Processes
Sometimes, the printer may still be processing a prior command (like cleaning printheads or scanning), and issuing a new command causes it to appear busy.
Incorrect Printer Settings
Misconfigured print preferences or selecting the wrong printer in the system may trigger the issue.

Step-by-Step Solutions to Fix the Canon "Printer is Busy" Error

Let’s go through effective troubleshooting methods to fix this issue. Follow them in order for the best results.

1. Restart Your Printer and Computer

A simple restart often solves temporary glitches.

Turn off your Canon printer.
Unplug it from the power source for at least 1–2 minutes.
Restart your computer or device.
Plug the printer back in and turn it on.

This clears the memory and refreshes the connection between devices.

2. Check and Clear Print Queue

A clogged queue can cause the busy error.

On Windows:
1. Open Control Panel > Devices and Printers.
2. Right-click on your Canon printer and select See what’s printing.
3. Cancel all pending jobs.
On Mac:
1. Open System Preferences > Printers & Scanners.
2. Select your Canon printer and click Open Print Queue.
3. Cancel or delete pending jobs.

Once cleared, try printing again.

3. Update or Reinstall Printer Drivers

Driver issues are a common cause of the busy error.

Visit the official Canon Support website.
Enter your printer model.
Download the latest drivers for your operating system.
Install the drivers and restart your system.

If the problem persists, uninstall the existing drivers first and then reinstall fresh ones.

4. Check Network or USB Connection

If your printer is network-based:

Ensure your Wi-Fi is stable and the printer is connected to the same network as your computer.
Try restarting your router.

If using a USB connection:

Ensure the cable is properly plugged in.
Test with another USB port or replace the cable if necessary.

5. Run Printer Troubleshooter (Windows)

Windows has a built-in troubleshooter.

Go to Settings > Devices > Printers & Scanners.
Select your Canon printer.
Click Manage > Run the troubleshooter.
Follow the prompts to automatically fix issues.

6. Reset the Canon Printer

A factory reset can eliminate software glitches.

On your printer control panel, go to Setup > Device Settings > Reset Setting.
Select Reset All.

Note: This will reset all network and custom settings, so you may need to reconnect your printer afterward.

7. Check for Paper Jams or Cartridge Issues

Sometimes the “Printer is Busy” error appears because the printer is physically stuck.

Open the printer’s paper tray and check for paper jams.
Ensure cartridges are correctly installed and have sufficient ink.
Clean the printhead if needed.

8. Stop Background Processes

The printer may still be engaged in internal processes like printhead cleaning or firmware updates. In such cases, give it a few minutes to complete the task before issuing new commands.

9. Firmware Update

Outdated firmware may cause errors.

Visit the Canon support website.
Download and install the latest firmware for your printer model.

This helps fix bugs and improve performance.

10. Check Default Printer Settings

Ensure your Canon printer is set as the default.

On Windows: Go to Control Panel > Devices and Printers, right-click on your Canon printer, and select Set as Default Printer.
On Mac: Go to System Preferences > Printers & Scanners and set your Canon printer as the default.
