What Is Cannot Detect Error

The "Cannot Detect" error message on your Brother printer typically indicates issues with the toner cartridge or drum installation.

  • If the toner cartridge is in place, grasp the assembly with both hands and gently sway it from side to side five to six times to evenly distribute the toner inside the cartridge.
  • Clean the three metal contacts on the right-hand side of each drum unit and the corresponding metal contacts on the right-hand side inside the printer.
  • Then, depress the green lock lever, and remove the toner cartridges from the drum units.
  • Securely place the cartridge and drum unit assembly back into its slot and close the front cover.
