Canon printers are popular for their durability, efficiency, and high-quality prints. However, like any machine, they can sometimes experience errors that hinder their performance. One such error is Canon printer error code 1702, a relatively common issue that users might encounter. This error typically appears when the printer is unable to recognize one or more of the ink cartridges, or when there is a problem with the ink cartridge installation. Understanding the causes of this error and how to fix it can save you a lot of time and frustration.

In this article, we will walk you through what Canon printer error code 1702 means, the possible causes, and step-by-step troubleshooting methods to help you resolve the issue.

What is Canon Printer Error Code 1702?

Canon printer error code 1702 is an error that typically appears on models such as the Canon PIXMA and Canon iP series. It indicates a problem with the ink cartridge(s). Specifically, error 1702 occurs when the printer cannot properly recognize one or more of the ink cartridges. This can happen for a variety of reasons, including issues such as:

Improper installation of the ink cartridges.
Incompatible ink cartridges.
Dirty or obstructed contacts on the ink cartridges.
Ink cartridge malfunctions or defects.
Software or communication issues between the printer and the ink cartridges.

When error code 1702 appears, the printer will usually stop printing and may display a warning light or a message on the screen. Depending on the model, you may also hear an error beep or see a flashing light. The problem is typically related to one or more ink cartridges being improperly detected or not recognized at all.

Common Causes of Canon Printer Error Code 1702

To effectively resolve Canon printer error code 1702, it is essential to understand the potential causes. Below are the most common causes:

Incorrect Ink Cartridge Installation: Sometimes, error 1702 occurs when the ink cartridges are not installed properly. If the cartridges are not seated correctly in their designated slots, the printer may not be able to detect them, triggering the error.
Incompatible Ink Cartridges: Using non-Canon or third-party ink cartridges can sometimes lead to errors like 1702. While third-party cartridges may seem like a cost-saving alternative, they may not always be compatible with your printer, causing issues such as failure to recognize the cartridge or poor print quality.
Dirty or Corroded Contacts: The electrical contacts on the ink cartridges and within the printer play a vital role in ensuring proper communication between the printer and the cartridges. If these contacts are dirty, corroded, or obstructed, the printer may fail to recognize the cartridges, leading to error code 1702.
Faulty Ink Cartridges: Sometimes, the problem may not be with the printer itself but with a defective or malfunctioning ink cartridge. A faulty cartridge that is either empty, damaged, or defective can lead to error 1702.
Software Issues: Occasionally, software problems can cause Canon printer error code 1702. Outdated printer drivers, a corrupted printer setup, or a miscommunication between the printer and your computer may prevent the ink cartridges from being recognized correctly.
Firmware or Hardware Issues: Less commonly, issues with the printer’s firmware or internal hardware could contribute to error 1702. This is especially true if there is a malfunction within the printer’s internal components responsible for detecting and communicating with the ink cartridges.

How to Fix Canon Printer Error Code 1702: A Step-by-Step Guide

Now that we have a clear understanding of the potential causes of error code 1702, let’s go through the troubleshooting steps to resolve the issue. These steps are designed to address both simple and more complex issues.

Step 1: Restart the Printer

A simple restart can often fix temporary glitches or errors in the printer’s system. Before proceeding with any other troubleshooting, it’s worth starting with a restart.

Turn off the printer by pressing the power button.
Unplug the printer from the power source for about 5-10 minutes to allow it to reset.
Plug the printer back in and turn it on again.
Check to see if error code 1702 is still displayed.

If the error persists after restarting the printer, proceed to the next step.

Step 2: Verify Ink Cartridge Installation

Improperly installed ink cartridges are one of the most common causes of error code 1702. To fix this, you need to ensure that the ink cartridges are installed correctly:

Turn off the printer and unplug it.
Open the printer cover to expose the ink cartridges.
Remove the ink cartridges carefully from their respective slots.
Inspect the ink cartridges for any visible damage, leaks, or signs of being improperly installed.
Reinstall the ink cartridges, ensuring that they click securely into place. Be sure that the cartridges are installed in their correct positions (for example, black ink in the black slot and color ink in the color slot).
Close the printer cover and plug the printer back in.
Turn the printer on and check if the error has been cleared.

If the cartridges were not seated correctly, this step should resolve the issue.

Step 3: Clean the Ink Cartridge Contacts

Dirty or corroded contacts on the ink cartridges or within the printer can prevent proper communication, leading to error code 1702. Cleaning these contacts is a simple but effective troubleshooting step:

Turn off the printer and unplug it from the power source.
Open the printer cover to expose the ink cartridges.
Remove the ink cartridges from the printer.
Use a soft, lint-free cloth to gently clean the metallic contacts on the cartridges. Dampen the cloth with a small amount of water or rubbing alcohol for better cleaning.
Also, clean the corresponding contacts inside the printer where the cartridges make contact.
Reinstall the ink cartridges and close the printer cover.
Plug the printer back in and turn it on.
Check if the error has been resolved.

This step will ensure that the contacts are clean and free from any dirt, ink buildup, or corrosion that could be causing the printer to fail to recognize the cartridges.

Step 4: Use Genuine Canon Ink Cartridges

One of the common causes of error 1702 is using non-Canon or third-party ink cartridges. While third-party cartridges may seem like an economical choice, they are often not fully compatible with Canon printers and may lead to recognition errors.

If you are using non-Canon cartridges, try switching to genuine Canon ink cartridges to see if that resolves the issue.

Turn off the printer and unplug it.
Remove the non-Canon ink cartridges.
Install genuine Canon ink cartridges.
Plug the printer back in and turn it on.
Check if the error code is resolved.

Switching to genuine ink cartridges is particularly helpful if the printer refuses to recognize third-party cartridges.

Step 5: Check for Ink Cartridge Defects

If the ink cartridges are properly installed, clean, and genuine, but you are still experiencing error 1702, it is possible that one or more of the ink cartridges are defective.

To check for defects:

Turn off the printer and unplug it.
Remove the ink cartridges.
Check each cartridge for any visible signs of damage or leakage.
If any cartridge is empty, damaged, or malfunctioning, replace it with a new cartridge.
Reinstall the new ink cartridges and close the printer cover.
Plug the printer back in and turn it on.

If the issue persists after replacing the ink cartridges, proceed to the next step.

Step 6: Update Printer Drivers and Firmware

Software issues can sometimes contribute to error code 1702. Ensure that your printer’s drivers and firmware are up to date to eliminate any compatibility issues or bugs that might be causing the problem.

Check for the latest printer driver: Visit the official Canon website and search for the latest drivers for your specific printer model.
Download and install the latest driver on your computer.
If there is a firmware update available, follow the instructions to update your printer’s firmware.
Restart your computer and printer after installing the updates.
Check if the error code 1702 still appears.

Updating your printer’s software can help resolve any software-related issues that might be interfering with cartridge recognition.

Step 7: Perform a Printer Reset

If none of the previous steps resolve the issue, performing a factory reset may help. Keep in mind that this will reset your printer to its default settings, and you may lose any custom configurations.

To reset your Canon printer to its factory settings:

Turn off the printer.
Press and hold the “Stop” or “Resume” button (this may vary depending on your model) while turning the printer back on.
Hold the button for about 5-10 seconds until the printer resets.
Release the button and allow the printer to reset.
Check if the error code is cleared after the reset.

Step 8: Contact Canon Support

If none of the above solutions work, the issue may be more complex and could involve internal printer hardware problems or other mechanical malfunctions. In this case, contacting Canon customer support for further diagnosis or taking the printer to an authorized service center would be the next step.

Conclusion

Canon printer error code 1702 is a frustrating issue, but it is usually solvable with a few troubleshooting steps. The error often occurs due to problems with the ink cartridges, such as incorrect installation, dirty contacts, defective cartridges, or incompatible third-party cartridges. By following the steps outlined in this guide—such as checking cartridge installation, cleaning contacts, using genuine ink cartridges, and updating software—you can usually fix the error yourself.
