What is the difference between a general error and a specific error code on my DCP-T420W?

A general error indicates a broad problem, often with internal printer components, and requires a more general troubleshooting approach like a power cycle. A specific error code provides a more precise indication of the issue, such as a paper jam, ink cartridge problem, or mechanical malfunction. The error code directs you to a more targeted solution, usually found in the printer's manual or on the Brother support website. Always try to identify the specific error code for quicker and more effective troubleshooting.
