Canon printer error 1668 typically occurs when there is a problem with the printer's print spooler service. The print spooler is responsible for managing print jobs and sending them to the printer. Here's how to fix error 1668 on a Canon printer:
Restart the Print Spooler Service:
The first step is to restart the print spooler service on your computer. Follow these steps:
Press the "Windows + R" keys to open the Run dialog box.
Type "services.msc" and press Enter to open the Services window.
Scroll down and find the "Print Spooler" service.
Right-click on the service and select "Restart."
Update Printer Drivers:
Outdated or incompatible printer drivers can also cause errors. Make sure you have the latest printer drivers installed for your Canon printer. You can download the drivers from Canon's official website.
Run Printer Troubleshooter:
Windows has a built-in printer troubleshooter that can help identify and fix common printer-related issues. Here's how to run it:
Go to "Settings" > "Update & Security" > "Troubleshoot."
Select "Printer" and click on "Run the troubleshooter."
Check for Windows Updates:
Sometimes, Windows updates can include fixes for printer-related issues. Make sure your operating system is up to date by installing the latest Windows updates.
