How to Fix Canon Printer Error B200: Step-by-Step Guide

If your Canon printer suddenly stops working and flashes Error Code B200, you are experiencing a hardware protection sequence. This error typically means the printhead is overheating or experiencing irregular voltage.

While Canon often recommends sending the device in for repair, there are several professional troubleshooting steps you can take at home to clear the error and restore your printer's functionality.

Step 1: The Power Drain (Hard Reset)

The most common cause of a false B200 error is a temporary voltage spike in the logic board. A simple restart will not fix this; you must perform a complete power drain.

• Turn off the printer using the physical power button.
• Unplug the power cord directly from the back of the printer, then unplug it from the wall outlet.
• Open the printer cover and check for any jammed paper or debris.
• Leave the printer unplugged for at least 30 minutes to allow the logic board capacitors to drain completely.
• Plug the printer directly into a wall outlet (bypass any surge protectors temporarily) and power it on.

Step 2: Reseat the Printhead and Ink Cartridges

If the error persists, the printer may be failing to read the microchips on your ink cartridges, or the printhead contacts may be dirty.

1. Turn on the printer and open the main access door. If the carriage does not move to the center, manually guide it gently.
2. Remove all ink cartridges and set them aside on a clean paper towel.
3. Lift the locking lever and remove the actual printhead (the carriage that holds the ink).
4. Wipe the gold contact pins on the back of the printhead with a lint-free cloth and rubbing alcohol.
5. Reinstall the printhead, push down the locking lever, and click the ink cartridges back into place.

Step 3: Professional Firmware Override

If physical cleaning and power draining do not resolve the B200 error, the printer requires a remote diagnostic to reset the internal page counter and clear the corrupted logic board cache. Our certified technicians can remote into your system, update the core drivers, and bypass the error code safely.
