If your Canon PIXMA TS3750i is experiencing connection problems, you want to remove your saved settings, or you’re preparing to give the printer to someone else, resetting it to its factory settings can be a useful solution.
The Canon PIXMA TS3750i provides two different reset options. You can reset only the network settings, which is useful when you’re having Wi-Fi problems, or you can perform a full settings reset, which returns the printer’s settings to their defaults. Canon’s instructions confirm that the full reset also restores the administrator password to its default.
In this guide, we’ll explain both options and show you how to factory reset your Canon PIXMA TS3750i step by step.
Before You Reset Your Canon PIXMA TS3750i
A reset removes settings you’ve previously configured, so it’s worth considering what you actually need to reset before starting.
If you’re only having trouble connecting the printer to Wi-Fi, you may only need to reset the network settings.
If you want to return the printer’s settings to their factory defaults, use the full reset option.
Important: A full initialization erases the printer’s network settings. Afterward, you’ll need to set up the printer’s Wi-Fi connection again before you can print over your wireless network.
Option 1: Reset the Network Settings
If your main problem is Wi-Fi connectivity, resetting only the network settings may be enough.
This removes the saved network configuration without performing the full printer settings initialization.
Step 1: Turn On the Printer
Press the Power button to switch on your Canon PIXMA TS3750i.
Wait until the printer has finished starting up.
Step 2: Press the Setup Button
Press the Setup button repeatedly until the printer’s LCD displays 10.
On the TS3750i, setup number 10 corresponds to resetting the LAN/network settings.
Step 3: Confirm the Reset
Press either the Black button or the Color button.
The printer will initialize its network settings.
Step 4: Reconnect the Printer to Wi-Fi
After the network reset, your previous wireless settings will no longer be available.
You’ll need to set up the printer’s Wi-Fi connection again before using it wirelessly. Canon provides setup instructions for reconnecting the TS3750i to a computer or smartphone.
Option 2: Perform a Full Factory Reset
If you want to reset all printer settings, use the full initialization procedure.
This is the option to use if you want to return the printer’s configurable settings to their defaults.
Step 1: Turn On the Printer
Make sure your Canon PIXMA TS3750i is switched on.
Step 2: Press the Setup Button
Press the Setup button repeatedly until 17 appears on the LCD.
On the TS3750i, setup number 17 is the option for resetting all settings.
Step 3: Start the Factory Reset
Press either the Black button or the Color button.
The printer will initialize its settings.
According to Canon’s documentation, this resets the printer settings and restores the administrator password to its default setting.
Step 4: Set Up the Printer Again
Once the reset is complete, you’ll need to configure any settings you want to use again.
If you normally use the printer over Wi-Fi, you’ll need to reconnect it to your wireless network. Canon’s official TS3750i setup guide provides instructions for connecting the printer to a computer or smartphone.
What Does a Factory Reset Remove?
A full reset returns the printer’s configurable settings to their default state.
This can include settings you’ve changed for:
- Network connections
- Wireless configuration
- Printer preferences
- Other configurable printer settings
- Administrator password
Canon notes that some items cannot be returned to their default state, including the current print-head position and certain SSL/TLS certificate-request settings.
Factory Reset vs Network Reset
It’s important to choose the right reset option.
| Reset option | Setup number | What it does |
|---|---|---|
| Network reset | 10 | Resets the printer’s LAN/network settings |
| Full settings reset | 17 | Resets all printer settings |
If you’re troubleshooting a Wi-Fi problem, starting with the network reset may be appropriate. If you need to completely reset the printer’s configurable settings, use the full reset option.
What to Do After a Factory Reset
After completing a full reset, the printer may no longer be connected to your wireless network.
If you want to continue using Wi-Fi printing, you’ll need to go through the printer setup process again.
Canon’s official TS3750i setup instructions cover connecting the printer to a computer or smartphone and completing the setup process.
You may also need to reinstall or configure the printer on your computer if it no longer appears as an available printer.
When Should You Factory Reset a Canon PIXMA TS3750i?
A factory reset can be useful in several situations, including:
You’re Having Persistent Wi-Fi Problems
If you’ve tried normal troubleshooting but the printer won’t connect properly to your wireless network, resetting the network settings can clear the existing network configuration.
You’re Changing Wireless Networks
If you’re moving the printer to a different Wi-Fi network, resetting the network settings can help remove the previous connection information before setting up the new connection.
You’re Giving Away or Selling the Printer
If you’re passing the printer to another person, a full settings reset can remove your configured printer settings and network information.
You Need to Restore Default Settings
If you’ve changed several printer settings and want to return the configurable settings to their defaults, the full reset provides a straightforward way to initialize them.
Does a Factory Reset Fix Every Printer Problem?
Not necessarily.
A factory reset primarily changes the printer’s settings. It doesn’t automatically fix physical problems such as:
- Empty ink cartridges
- Paper j
