Check Ink Cartridges: Open the printer’s front cover and inspect the ink cartridges. Make sure they are properly installed and seated in their respective slots. Also, check if any of the ink cartridges are low on ink or need replacement.

Replace Problematic Cartridge: If you identify a specific ink cartridge causing the error, try removing it and reinserting it carefully. If the problem persists, consider replacing the problematic cartridge with a new one.

Clean the Contacts: Ink cartridge contacts can sometimes get dirty or dusty, causing connection issues. Gently clean the metal contacts on both the ink cartridges and the corresponding slots inside the printer using a lint-free cloth or cotton swab.

Restart the Printer: Turn off the printer, unplug it from the power source, wait for a few seconds, and then plug it back in. Turn on the printer and check if the error has cleared.

Update Printer Firmware: Check if there is a firmware update available for your Canon printer model. Visit Canon’s official website, enter your printer model, and download the latest firmware update. Installing updated firmware might resolve the issue.

Perform a Hard Reset: If the B203 error persists, you can try performing a hard reset on your Canon printer. To do this, follow these steps:

• Turn off the printer.
• Unplug the power cord from the printer and the power outlet.
• Wait for at least 5 minutes to allow any residual power to dissipate.
• Plug the power cord back into the printer and the power outlet.
• Turn on the printer and check if the error is resolved.

Check for Paper Jams: Sometimes, even ink cartridge errors are triggered by paper jams or other obstructions. Open the printer’s front and rear covers and check for any stuck paper or debris.

If the B203 error persists despite trying the above steps, it’s possible that there is an internal hardware issue with the printer. In such cases, it’s best to contact Canon’s customer support or bring the printer to an authorized service center for further diagnosis and repair. They can provide specific guidance and assistance tailored to your Canon printer model and the exact nature of the B203 error.
