My brother MFC 9440CN printer said something like Yellow toner end of life.
I knew these high capacity toners should not be out of life. It is just like the car maintenance indicator.
But my printer wouldn’t print!
So I found this to reset it — worked like a charm.
With power on, open the toner access main door. You will get a “Cover is Open” message on the LCD.
Press the “Clear/Back” button and you will be taken to the toner “Reset Menu”
You can then scroll through the reset options for the printer’s toner cartridges:
B.TNR-S – Black toner small cartridge (TN-110)
B.TNR-H – Black toner high-capacity cartridge (TN-115)
C.TNR-S – Cyan toner small cartridge (TN-110)
C.TNR-H – Cyan toner high-capacity cartridge (TN-115)
M.TNR-S – Magenta toner small cartridge (TN-110)
M.TNR-H – Magenta toner high-capacity cartridge (TN-115)
Y.TNR-S – Yellow toner small cartridge (TN-110)
Y.TNR-H – Yellow toner high-capacity cartridge (TN-115)
Select the cartridge size you have and the colour you want to reset, and press OK. Since I had small cartridges, I used the S options for all three colours.
Each cartridge must be reset individually. Press “1″ to reset.
Press “Clear/Back” to get out of the menu, then close the door.
It’s possible to reset the values for other consumables on the printer as well. Hold down both 3 and 9 at the same time, and you’ll get a menu to reset:
Drum
Belt Unit
PF Kit MP
PF Kit 1
PF Kit 2
Fuser
Laser
