How to Reset a Brother HL-3040CN Printer

How to Reset a Brother HL-3040CN printer


Step 1. Open the front cover of the Brother printer, this would be the cover where the toner and drum are put in, not the paper. The cover should remain open for the whole process, or until the printer directs you to close it.


Step 2. Press both the Secure Print and Cancel buttons at the same time. You should see a message appear on the screen that says “K-TNR-STD” If you do not see this message then you might have to clear any print jobs that are in the print queue.


  • K is for Black, M is for Magenta, C is for Cyan, and Y is for Yellow

  • TNR is for toner

  • STR is for starter cartridge (that is, the cartridge that originally came with your printer)

  • STD is for standard toner

  • HY is for high yield toner (not all models will have this option)


Step 3. Use the + and - buttons to make a selection for the toner you want to reset. In some cases you will have to reset all of the colors, which means going through this process a total of 4 times


Step 4. Press the Ok button once you have made a selection


Step 5. The display screen will show “Ok?” to confirm your selection. Hit the Ok button one more time and it will reset the printer. Close the lid and resume printing.
