I refiilled tho toner cartrage with a generic toner as i have bin doing for years,and it still says tonen life end. i know that in the past when i bought generic toner it came with instuctions how to reset it,

I assume you mean toner waist bin? if so the bin should be visable when you open the printer up, use a hoover to get out as much as you can, watch out for static shocks tho!!

i have brohter dcp7030 laser printer .earlier toner is empty si i refiiled the toner but toner giving me not printout.printer is display the message of toner end so plase me suggest the reset of this ptinter

This often happens when cartrage has run past changing point. remove cartrages starting at top and CK for ink. Run cleaning page until clear

I replaced already new toner cartridge for my brother fax machine mfc-2820 but still the on screen message is appearing on the display "TONER LIFE END".
Pls help me to solve this problem.

You need to look at the toner cartrage if it was a new or compatible cartrage bought to replace the old one the problem would not exist unless the printer is broken.

Thier is a counting gear on the left side and on new or replacement cartarages it is in the 11 oclock postion when it is new. When the toner is all used it moves to the 3 oclock postion. What you need to do if you refilled the toner from a refill kit is to manually move the gear.

I believe thier is two ways to do this one buy a reset gear tool.

The other way that I do is to remove the three screws carefully that holds all the gears in place. Dont worry as it is just the cover and you can not really break the cartarage unless you strip the screws.
Once opened manually using your hand push firmly on the counting gear until you move it back to the 11 oclock postion. Then carefully reassemble the cover.
Once you place the cartrage back in the light will go off on its own and the toner counter will be reset.

Do not try to only move the counter you may get a few pages but this is bad for the printer
Do not leave any toner in the cartrage when refilling as this contaminates the toner and really shortens the refill life, try to get all the toner out as possible before refill.
Do not keep reshaking the cartrage and place it back in the printer, everytime you insert the cartarage the it can snag or be inserted a tiny bit wrong and break the gears in the printer. Do so in emergencys only, the rest of the time just refill the toner. $10 with delivery on ebay

I'm going to provide you a solution worth many dollars now you can use your left over half filled cartidges and in future also use the cartridges to the extreme.
1. Go to menu and select manual override for toner cartridges and then only replace toner when the print quality starts to suffer. This can save you thousands of dollars over the life of this fine printer.

What model printer do you have? Try gently shaking the cartridge end to end. Maybe the toner is wicked up like sand and needs to be redistributed.

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.

Make sure that you are not using generic supplies. Using generic supplies or supplies that have been refilled will cause the unit to give false errors. There is white piece of plastic inside the semi circular opening, if you do not see a white semi circular opening it is either a generic toner or starter toner and you will need to replace the toner with a authentic toner. You may try this also: 1. Remove the drum and toner, separate the drum and toner and then rock the toner from side to side. 2 Put the drum and toner back together and clean the corona wire ten times. 3 Put the drum and toner back inside the machine and close the cover, if you still have toner life end try this: a Open the front cover b press the options key, the LCD will say "replace drum?" c press the start key. and then press 10 on your dial pad. the display should say accepted for about 2 seconds and then say cover open. d close the cover, if the display still has toner life end, you will need to replace the toner
