How to remanufacture Brother TN420 TN450 TN2210 TN2220 toner Cartridge for use in DCP 7030, DCP 7040, DCP 7045N, HL 2140, HL 2150N, HL 2170W, MFC 7320, MFC 7340, MFC 7440N, MFC 7840W and reset the toner counter.
There are 3 different yielding toner cartridges:
Starter cartridge -- 700 pages at 5%
TN420 (TN2210 Europe) - 1200 pages at 5%,
TN450 (2220 Europe). - 2600 pages at 5 %
The drum unit DR420 (DR-2200 Europe) is rated for 12,000 pages.
Fuser assembly haS a life of 50,000 pages.
When you instal a new toner cartridge, the bias voltage is set to a high voltage.
As the cartridge is used, the bias voltage is gradually reduced down and the density increases.
This is necessary because a new toner cartridge has a tendency to print light, and to keep the density level even throughout its life, the density bias voltage is reduced accordingly.
Each time a new cartridge is installed, the bias voltage is reset to the high voltage point, and the cartridge page count is reset to zero.
Since different yields would dictate different decreases in density over time, the cartridge uses different reset gears.
The developer roller presents the good toner to the drum, but it also pick up the waste toner.
So, at the end of its life, the toner cartridge is full of waste toner.
Failure to clean the toner cartridges properly, will causes backgrounding.
