How can I resolve a "Low Ink" or "Replace Toner" error on a Brother printer if I just replaced the cartridge?

If you've just replaced the ink or toner cartridge and the Brother printer still shows a "Low Ink" or "Replace Toner" error, ensure the new cartridge is correctly installed and that any protective seals or tabs have been removed. Sometimes, printers require a reset after cartridge replacement. Check your printer's manual for specific instructions on how to reset the cartridge counter, which might involve a button combination or navigating through the printer's menu.
