What is the purpose of the "B" or "C" code appearing before an error number on some Canon printer displays?

The "B" or "C" code preceding an error number on some Canon printer displays often refers to the type of error. 'B' codes typically relate to the paper feed mechanism or paper jams, while 'C' codes are generally associated with ink-related issues, such as cartridge problems or print head malfunctions. Knowing this distinction can help narrow down the potential cause when consulting Canon's troubleshooting resources.
