Owners of PIXMA multifunctional devices often need to reconnect their devices to a new wireless network or troubleshoot connection issues that can't be resolved using standard methods. The question of how to reset the Wi-Fi on a Canon 3640 printer becomes especially pressing after changing the router or password, or after purchasing a used device that retains previously used configurations. A malfunctioning communication module can block document printing and scanning, turning a functional device into a useless device.
Clearing network settings doesn't require advanced programming knowledge or complex tools, but it does require strict adherence to a specific sequence of steps. In this article, we'll cover all available methods for restoring network settings to their default state, including using the buttons on the device's case and menu. Understanding these processes will help you quickly restore functionality. Canon PIXMA TS3640 and avoid repeated mistakes during setup.
It's worth noting that resetting the network doesn't delete personal data or paper format settings from the scanner; it only affects the local network connection settings. This is a safe operation that can be repeated multiple times without risking damage to the device's hardware. The key is to follow the instructions carefully, as the menu interface can be confusing for beginners.
Preparing to reset network settings
Before attempting any drastic network configuration changes, ensure the device is ready to receive commands. Make sure the printer is turned on and in standby mode, not in deep sleep with the screen blank. The power indicator should be solid, not flashing, indicating it's in power-saving mode.
It's also important to check if printing or scanning is currently in progress, as interrupting these tasks can cause paper jams or software crashes. If you see a cartridge error or out-of-paper message on the screen, it's best to troubleshoot these issues first. Stable condition devices are the key to successful execution of the reset command.
⚠️ Important: If you plan to reconfigure your printer to a new router, make sure you know the password for the new Wi-Fi network in advance. After resetting the old settings, the device will enter connection standby mode, and you will need to enter the new password immediately.
Make sure you're in a strong signal area if you plan to reset the router immediately. While the reset itself can be performed at any distance from the router, proximity is key for subsequent synchronization. This will avoid unnecessary network search issues during the setup process.
Direct reset method via button combination
The fastest way to clear network settings on a model Canon TS3640 — using a special button combination on the control panel. This method doesn't require entering a deep menu and works even if the device's interface is partially locked or frozen. First, find the button marked with a wireless network icon (usually it looks like an antenna or a smartphone).
Press and hold this button until the power indicator starts flashing, then release it. Then, quickly press the Color button, followed by the Black button. This sequence will initiate network reset mode. The screen may flash or beep to confirm the command was successfully completed.
After completing these steps, the Wi-Fi indicator will begin flashing, indicating the device has entered network search or access point mode. This means all saved passwords and SSIDs have been cleared from memory. The printer is now ready for reconfiguration, just like a new device out of the box.
☑️ Pre-reset check
Reset via the device setup menu
If the physical method doesn't work for some reason, or you prefer visual control, you can use the built-in menu. Press the button Menu (or the button with the image of a wrench/tool) on the control panel. Use the navigation arrows to find the section responsible for device settings, which is often labeled as Device settings or the gear icon.
Inside the menu, find the item Reset settings (Reset settings). The system will prompt you to select which settings you want to clear. Select the option. LAN settings or Network reset. Confirm the action by clicking the button. OK or YesThe device will warn you that your current settings will be lost.
After confirmation, the printer will reboot the network module. A message indicating the process is complete may appear on the screen. This method is preferable if you want to be sure that only network settings are being reset, and not, for example, paper size or print quality settings.
What to do if the menu is not responding?
If the screen doesn't respond to touch, the device may be frozen. In this case, unplug the power cord for 10-15 seconds, then plug it back in. After it fully boots, try accessing the menu again.
Full reset to factory settings
In situations where you need to delete absolutely all user data, including not only Wi-Fi, but also region settings, paper size, and system preferences, a full reset (Factory Reset) is used. This procedure will restore Canon PIXMA TS3640 to the state it was in when it left the factory assembly line. Use this method with caution if you simply need to change your Wi-Fi password.
To perform a hard reset, go to the settings menu and select Reset all or Factory resetThe system will ask for confirmation, as this action is irreversible without manually reconfiguring all settings. After confirmation, the device will reboot, which may take up to two minutes.
It's important to understand that after this procedure, you'll have to reselect your interface language, time zone, and region. Your network settings will also be completely cleared. This is a last resort measure that helps with serious software issues that cause the printer to behave erratically.
| Reset type | What is being cleared? | Impact on printing | Complexity |
|---|---|---|---|
| Network reset | Wi-Fi password, SSID, IP address | It doesn't affect | Low |
| Reset LAN settings | All network parameters, ports | It doesn't affect | Average |
| Factory Reset | All settings, language, region, network | Requires a new setup | High |
| Resetting counters | Ink consumption data only | It doesn't affect | High |
Remember that a hard reset doesn't affect the physical wear of the components or the ink levels in the cartridges; it only affects the software. If you simply want to reconnect the device to the router, limit yourself to the network reset described in the previous sections.
Wi-Fi status indication after reset
Understanding the signals your printer emits is critical for diagnostics. After a successful Wi-Fi reset, the wireless network indicator on the control panel will turn off. Canon 3640 will start blinking. The blinking frequency may vary, but it usually means the device is in Access Point Mode.
If the indicator light is solid, the printer has successfully connected to a network (it may have automatically connected to one of the saved networks if the reset was incomplete, or to the default network). If the indicator light doesn't light at all, check whether the wireless module is enabled in the device menu.
In some cases, the indicator may blink very rapidly, indicating a connection error or network search. This is normal behavior immediately after a reset, when the printer is attempting to find previously known networks. If the blinking continues for more than 5-10 minutes without success, the module may enter sleep mode.
⚠️ Note: The interface and indicator behavior may vary slightly depending on the firmware version. If the lamp's behavior differs significantly from what is described in the instructions, please consult the official user manual for your specific device version.
Resetting Wi-Fi after clearing
Once you've successfully reset the Wi-Fi on your Canon 3640 printer, it's time to reconfigure it. The easiest way to do this is using the mobile app. Canon PRINT Inkjet/SELPHYDownload it to your smartphone, connect to the same Wi-Fi network you plan to connect the printer to, and launch the app.
The app will automatically detect the printer in setup mode. Follow the on-screen instructions: select your Wi-Fi network from the list and enter the password. The printer will receive data and connect. Alternatively, use the button. Wireless on the printer itself to search for networks, if the model supports direct input from the screen, although on the 3640 series the WPS method or an app is more often used.
If you're using WPS (Wi-Fi Protected Setup), press the WPS button on your router, then press the corresponding button on the printer (often you need to hold down the wireless button). The devices will find each other and exchange passwords automatically, without the need to enter the security key manually.
Common problems when resetting
Sometimes users encounter a situation where the printer doesn't respond to reset commands or can't connect to the network after cleaning. One common cause is the use of a 5 GHz network. The Wi-Fi module in the model Canon TS3640 Only works in the 2.4 GHz band. If your router only broadcasts 5 GHz or combines them into a single network with 5 GHz as the priority, the printer may not see the network or connect.
Another issue is a hidden SSID (network name). If your network name is hidden, the printer won't be able to find it automatically. In this case, you'll need to temporarily enable the network name display in your router settings or configure it via WPS. Also, make sure MAC address filtering isn't enabled on your router, as this could block new connections.
If all else fails, try updating the printer firmware. Sometimes older firmware versions contain bugs that prevent the network module from working properly. The update can be performed via a USB cable by connecting the printer to a computer, or through the device menu if it's at least partially functional.
Why doesn't the printer see the network after a reset?
Most often, the problem lies with the frequency range. Make sure your router is broadcasting a 2.4 GHz signal. Also, check if your router limits the number of connected devices. Try moving the printer closer to the router to eliminate signal issues.
Is it possible to reset the settings without accessing the menu?
Yes, the button combination (Wireless + Color + Black) allows you to reset the network without entering the menu. However, for a full factory reset, entering the menu is usually required, as it is a more in-depth system operation.
Will this reset the web interface admin password?
Network Reset returns the IP address and Wi-Fi password to factory defaults, but the password for accessing the printer's web management interface (if changed by the user) may remain. To completely reset all passwords, use the Reset All option.
Do I need to remove the printer from the system before resetting?
It's a good idea to remove the old device from the printer list on your computer and phone before resetting to avoid driver conflicts. After the reset and new setup, the system will detect it as a new device, and you can install the new drivers.
