Brother HL4150CDN Toner Counter Reset for TN340 and TN348

For some reason once in a blue moon when a new toner is installed the reset switch isn’t triggered and the toner counter doesn’t get reset. The following is a manual reset for your printer that you can use to reset the toner counter.

  1. Open the front cover of your Brother HL-4150CDN laser printer where you can access its toner cartridges.
  2. Press the Cancel & Secure Print buttons at the same time to see the toner menus on the screen.
  3. Press the “+” or “-” to select the toners you need to reset. Press “OK” to reset the selected toner cartridge. Repeat for each toner cartridges colour as required.
  4. Close the front cover.

DONE.Note: for selecting the correct toner you need to understand the cartridge code system Brother uses:

  • Black is K, Magenta is M, Cyan is C and Yellow is Y
  • TNR = toner
  • STR = starter cartridge (the toner cartridges that came with your printer)
  • STD = standard toner or TN340
  • HC = high yield toner or TN348

Note that some users have had to turn the printer off and back on again to get the reset menu to show.
