Reddit post by u/Fast_Cranberry_1013 (r/printers). Brother MFC-L3780CDW failed with a persistent No Toner message after 4 months despite repeated official troubleshooting. Brother chat repeatedly looped the same article and effectively would not proceed with warranty repair unless a full set of new genuine Brother toner cartridges had been purchased.
