What it means

Brother shows Cannot Detect when the inkjet printer does not detect an ink cartridge. In its help for MFC-J models, Brother lists causes such as a cartridge installed too quickly or incorrectly, a used cartridge reinstalled, non-genuine ink, an air bubble in a new cartridge and the wrong model cartridge. The message does not mean the printer is faulty: almost every cause is in the cartridge or how it was installed.
