Toner life end, with fresh cartridges?? - Brother Office Equipment & Supplies

Remove the "end-of-life" toner-cartridge, and responsibly recycle it.
Insert a new toner-cartridge.
Click 'Y' for "yes".

As posted by another before. Remove toner cartridge and cover small window in RHS with opaque tape eg black gaffer tape.

Did you pull the plastic tape on the cartridge?

If your cartridge has a lever on the left side near the rear, it needs to be reset, and there's a lever inside on the left that can stick and cause that error. You need to wiggle and pull that lever until it moves freely again.

When the Toner Life End LED flips on, requires you to replace the cartridge, even when there's still toner left in the cartridge. The machine detects end of life by shining a light through from one side to the other.
To circumvent the detection mechanism, remove the cartridge and put a piece of masking tape over or jam a little bit of paper into the clear opening/circle on the right side of the toner cartridge, and then pop the cartridge back in. Eventually, you'll start seeing streaks, and then you'll know that the cartridge is truly empty.

There are two units in the machine, a toner cartridge and a drum unit. The toner clips into the drum and then is inserted in the machine. If you changed the toner and you still get this message, you may have a bad or damaged toner detection sensor.

did you reset the toner life?

open the front cover, press the option button, on the screen will display ''reset toner life 1 yes 2 no ''
press 1 and close the cover.

toner life reseted

There is no reset code the likely thing is that you have a faulty toner cartridge. Put another new one in and check the machine then.

Before you try the above shake the toner cartridge and tap it some more as it may also be the toner inside have become solid and needs breaking up.


Hope one of the above works for you
Thanks J
