Basic Troubleshooting Steps

To troubleshoot the issue of your Canonet QL17 GIII shutter not firing, there are a few basic steps you can take.

  • First, check the battery to ensure it’s fresh and inserted correctly.
  • Next, verify that the film is loaded properly and that the film advance lever is in the correct position.
  • Additionally, inspect the film pressure plate for any jams or damage.
  • Finally, gently press the shutter release button multiple times to see if it activates.


Ensure you have fresh batteries inserted correctly in your Canonet QL17 GIII camera, as this can affect the firing of the shutter.

Check the battery life to ensure it isn’t depleted. The Canonet QL17 GIII camera requires a 1.35V mercury battery (PX625) or a replacement zinc-air battery (PX625A).

If your camera is equipped with a battery voltage check button, press it to verify the battery voltage.

Additionally, inspect the battery compartment for any signs of corrosion or damage. If you notice any issues with the battery or the battery compartment, replace the battery or clean the contacts as necessary.

Properly inserting the battery with the correct polarity is crucial for the camera’s electrical functions to work correctly.

Film loading

After confirming that your Canonet QL17 GIII camera’s battery is properly inserted and functioning, let’s now address the next step in troubleshooting: film loading.

To ensure proper film loading, follow these steps:

  1. Film advance: Check if the film advance lever moves smoothly and advances the film to the next frame. If it feels stuck or doesn’t move at all, there may be an issue with the film transport mechanism.

  2. Frame counter: Look through the viewfinder and check if the frame counter advances as you advance the film. A malfunctioning frame counter could indicate a problem with the film advance mechanism or the frame counter mechanism itself.

  3. Rewind knob: Make sure the rewind knob rotates freely. If it feels stuck or doesn’t turn, it could prevent the film from advancing properly.

  4. Exposure meter: Check if the exposure meter responds to changes in lighting conditions. If the exposure meter isn’t functioning correctly, it may affect the camera’s overall operation.

Film pressure plate:

Inspect the film pressure plate for any signs of jamming or damage. The film pressure plate plays a crucial role in ensuring proper film alignment and flatness during the film transport mechanism. If the pressure plate is jammed or damaged, it can result in film advance issues and ultimately prevent the shutter from firing.

To troubleshoot this issue, follow these steps:

  • Check for any debris or foreign objects that may be obstructing the pressure plate.
  • Ensure that the pressure plate is securely fastened and not loose or misaligned.
  • Verify that the pressure plate adjustment is correct according to the camera’s manual.
  • Examine the film flatness by gently pressing down on the film while inspecting the pressure plate.

If you notice any abnormalities or suspect that the pressure plate may be causing the issue, it’s recommended to consult a qualified camera repair technician for further assistance.

Shutter release:

To troubleshoot the issue with the shutter not firing on your Canonet QL17 GIII camera, try gently pressing the shutter release button multiple times to check for activation.

The shutter release button is responsible for initiating the shutter mechanism, which controls the exposure and captures the image. Sometimes, the shutter button may become stuck or unresponsive due to debris or mechanical issues.

By pressing the button several times, you can test if it’s functioning properly or if there’s a delay or lag in the shutter speed.

If the shutter release button still doesn’t activate the shutter, it could indicate a more significant problem with the camera’s internal mechanism. In this case, it’s recommended to seek professional assistance from a qualified camera repair technician.

Consult the Manual

If you’re experiencing issues with your Canonet QL17 GIII camera, one of the first steps you should take is to consult the user manual for troubleshooting guidance specific to your camera model.

The manual is a user-friendly guide that provides detailed information on troubleshooting techniques, common issues, and troubleshooting tips.

Here are some reasons why consulting the manual is important:

  • Accuracy: The manual is specifically designed for your camera model, ensuring that the troubleshooting process is accurate and effective.

  • Comprehensive information: The manual covers a wide range of topics, including troubleshooting techniques for various camera functions and components.

  • Step-by-step instructions: The manual provides clear and precise step-by-step instructions on how to diagnose and resolve common issues, making it easier for you to troubleshoot the problem.

  • Safety precautions: The manual also includes important safety precautions that you should follow while troubleshooting, ensuring that you don’t cause any further damage to your camera.

Seek Professional Help

If consulting the manual doesn’t resolve the issues with your Canonet QL17 GIII camera, it’s time to seek professional assistance from a qualified camera repair technician.

While troubleshooting techniques can be helpful, there are complex components within the camera, such as the shutter mechanism, that require specialized knowledge for repair. Attempting to fix it yourself without proper training can lead to further damage.

A professional camera repair technician has the expertise and tools necessary to diagnose and fix the problem accurately. They’re familiar with the inner workings of the Canonet QL17 GIII and can identify common issues that may be affecting the shutter’s functionality. By seeking their help, you can ensure that your camera receives the proper maintenance it needs.

Some common issues that could cause the shutter not to fire include a misaligned or worn-out shutter curtain, a faulty shutter release button, or a malfunctioning electromagnet. These problems can be tricky to diagnose and repair without the right knowledge and tools.


In conclusion, if you’re experiencing issues with your Canonet QL17 GIII shutter not firing, it’s important to prioritize safety and seek professional assistance if needed.

While there are some basic troubleshooting steps you can take, it’s advisable to consult the user manual for specific guidance.

If the problem persists, reaching out to a qualified camera repair technician is the best course of action to ensure the longevity and proper functioning of your camera.
