How to Fix a Canon Printer Not Printing

Why Is My Canon Printer Not Printing?

A printer can appear ready while a problem elsewhere prevents the job from reaching the paper. Before assuming the printer has failed, identify where the printing process stops.

Common causes include:

• The printer is off or still initializing.
• The USB connection is loose or unavailable.
• The printer is no longer connected to WiFi.
• The computer is sending the job to another printer.
• A previous job is stuck in the print queue.
• The printer is shown as offline.
• Paper is missing, jammed, or loaded incorrectly.
• Paper settings do not match the loaded media.
• An ink or cartridge issue is present.
• The printer is displaying an error or support code.
• The printer driver or software is not working correctly.

Step 1: Make Sure the Canon Printer Is Ready

Check the printer before changing anything on the computer.

1. Make sure the power cord is securely connected.
2. Turn on the printer.
3. Wait while the printer initializes.
4. Check the display or indicator lamps for an error.
5. Make sure covers and trays are positioned correctly.

Some printers take time to initialize or process a large print job. If the power indicator shows that the printer is still processing, allow it time to become ready before sending additional jobs.

Step 2: Check the Printer Connection

The next step depends on whether the printer uses USB or a network connection.

If the Canon Printer Uses USB

• Check that the cable is firmly connected to both the printer and computer.
• Try a different working USB port if available.
• If practical, connect the printer directly to the computer while troubleshooting instead of using an intermediate USB hub.
• If another suitable cable is available, test whether the original cable is causing the communication problem.

If the Canon Printer Uses WiFi

• Make sure the printer's network connection is active.
• Confirm that the wireless router is working.
• Check that the computer and printer are using the intended network.
• If the router name or password changed, set up the printer for the current network again.
• Move the printer closer to the router temporarily if the wireless signal is weak.

Step 3: Make Sure the Correct Canon Printer Is Selected

If several printers or old printer installations appear on the computer, a document may be sent to the wrong device.

Before printing:

1. Open the application's Print window.
2. Review the selected printer.
3. Select your actual Canon printer model.
4. Check that an old or disconnected printer is not selected.
5. Send a small test document.

The printer driver selected for the job should correspond to the printer you are actually using.

Step 4: Clear Stuck Print Jobs

One failed job can sometimes prevent later documents from printing.

1. Open the print queue for the Canon printer.
2. Look for jobs that are paused, stuck, or showing an error.
3. Cancel unnecessary jobs.
4. Allow the queue to clear.
5. Send one simple test page.

Avoid repeatedly clicking Print while a job is already stuck. This can create a longer queue and make troubleshooting more confusing.

Step 5: Check Whether the Canon Printer Is Offline

If the computer reports that the printer is offline, confirm the physical or network connection first.

On systems that provide an offline printing option, open the printer queue and check whether an offline mode has been enabled. If it was enabled unintentionally, disable it and test printing again.

Do not treat the offline setting as the only cause. A printer can also appear offline because the computer can no longer communicate with it.

For a WiFi printer, recheck the network connection. For a USB printer, recheck the cable and USB port.

Step 6: Check Paper and Paper Settings

A printer may stop before printing if it cannot feed paper correctly or if its paper settings require attention.

• Make sure paper is actually loaded.
• Remove badly curled, folded, or damaged sheets.
• Align the paper stack before loading.
• Position the paper guides correctly.
• Check for a paper jam or torn paper.
• Make sure the output path is clear.
• Check whether the selected paper size and media settings match the intended print job.

If the printer displays a paper-related message, resolve that message before repeatedly resending the document.

Step 7: Check Ink, Cartridges, and Print Quality

If the printer accepts the job but the page is blank, faded, missing a color, or otherwise incomplete, the problem may be related to ink or print quality rather than communication.

Check:

• Whether an ink warning or cartridge error is displayed.
• Whether cartridges or tanks are installed correctly.
• Whether protective material was removed from a new cartridge.
• Whether the printer reports low or unavailable ink.
• Whether a nozzle check shows missing lines or colors.

If a nozzle check indicates a print-quality issue, use the maintenance procedure appropriate for your exact Canon printer model.

Step 8: Check for an Error or Support Code

If the printer shows a specific error code, support code, warning light pattern, or message, use that information as the main troubleshooting clue.

A paper jam, cartridge problem, cover warning, connection issue, or another printer condition may prevent printing until the displayed problem is resolved.

Do not ignore a recurring code and repeatedly power cycle the printer without identifying what the code represents.

Step 9: Check the Canon Printer Driver and Software

If the printer is powered on, connected, and free of visible errors but the computer still cannot print, check the printer installation.

1. Confirm that the installed printer corresponds to the exact Canon model.
2. Check whether the operating system still detects the printer.
3. Restart the computer if printing stopped after a temporary software or communication problem.
4. If the printer driver is missing, outdated, or damaged, install the appropriate software for the exact model and operating system.
5. Test with a simple document after installation.

Avoid installing random printer-driver packages from unknown download websites.

Step 10: Restart the Printer, Computer, and Network

After checking the obvious causes, a controlled restart can help restore communication.

1. Cancel unnecessary print jobs.
2. Turn off the printer normally.
3. Restart the computer.
4. If the problem is network-related, make sure the router is functioning normally.
5. Turn the printer back on.
6. Wait until it is ready.
7. Send one test page.

If the printer repeatedly loses its network connection after restarting, troubleshoot the wireless connection rather than continuing to restart it.

Canon Printer Not Printing: Quick Diagnosis

Canon Printer Not Printing From a Computer

When the printer itself appears ready but printing fails only from a computer, focus on communication, printer selection, the print queue, and the printer installation.

Test whether the problem affects every application or only one program. If one application cannot print but others can, the problem may be related to that application's print settings rather than the printer itself.

If no application can print, return to the connection, queue, printer selection, and driver checks above.

Canon Printer Connected to WiFi but Not Printing

A successful WiFi connection does not automatically guarantee that the computer is communicating with the correct printer installation.

Check that:

• The printer remains connected to the intended network.
• The computer is on the appropriate network.
• The correct Canon printer is selected.
• The print queue is not paused or blocked.
• No printer error is preventing printing.

If the printer was recently moved to a new router, update its network configuration and make sure the computer can discover it again.

Common Mistakes to Avoid

• Reinstalling drivers before checking whether the printer is simply turned off.
• Sending the same document repeatedly while the queue is blocked.
• Selecting an old printer installation with a similar name.
• Assuming WiFi is working because the router itself has internet access.
• Ignoring a paper, cartridge, or support-code warning.
• Using an unreliable USB hub while troubleshooting.
• Downloading drivers from unknown third-party websites.
• Running repeated maintenance cycles without checking print-quality results.
