Brother TN-730 / TN-760 Cannot detect black cartridges error message

Your printer has most likely been manufactured after the date of the toner ink cartridge chip that is located on the bottom of the cartridges. eg. Printers manufactured before October 2018 the cartridge works on but printers manufactured after that date the cartridge will now work.

If you have received this error with a toner purchased from Printer Refillers please bring it back with your bill and we can exchange cartridge for a re-manufactured cartridge as this will solve the issue. Unfortunately, the only other way to solve this issue is to move the chip from your old cartridge to the new one. However, if you do this with a cartridge purchased from Printer Refillers your warranty will be void. So we strongly recommend coming back to see us with the cartridge.
