Samsung still say's toner low even when new toner put in

replace fuse chip in toner

Toner cartridge original or refill?

In the refill toner cartridges sometimes no replace the chip on it,put a new one chip.

This is due to a sensor that reads the actual cartridge is defective not the actual cartridge or the cartridge is one that was refilled and thus not put back togeather the way it should have been. So its ether or a refilled cartridge or a bad sensor. Both req. repair in some sort.

Have you tried putting a shim under it to make it higher?
Seriously...If the toner is low, you have to buy a new toner cartridge to replace the on that's low. No ink toner = no print.
Visit Staples, Best Buy, etc. to buy a new toner cartridge.

Try these steps:
1. Press MENU # 1 9 3 4 in sequence rapidly. The LCD panel should now display TECH.
2. Press MENU, and then press ENTER. The LCD panel will display Tech Mode.
3. Press the left arrow (<) button once. The operator panel will display NEW CARTRIDGE.
4. Press ENTER. The operator panel will display [YES].
5. Press ENTER. The toner warning message should be gone.
6. To exit TECH MODE, press MENU # 1 9 3 4 in rapid succession, as if you were dialing a phone number. The operator panel should no longer display TECH.
Let me know if it doesn't work as there is another possible solution.

You have to reset the drum count on the printer after you replace the drum. Call dell tech support they will not charge you for help resetting the drum even if you are not in warrenty.

ensure that the one you install is the exact model name and number, if this is correct, try unistallling once again and check one more time,

you might want to get a new cyan toner if this still fails, i dont think there is a prob in your machine, cheers

clean the contacts on toner and in printer, shake the toner before putting it in. Reset printer via the html menu!

If this IS a CLP-510, first make an information confirmation print.
Press MENU, then press ENTER, and ENTER again.

Look at the counter for the imaging unit, is it a low count confirming that you have indeed replaced it ?
If not you will need to reset the counter.

Check the counters for the toner cartridges, and check the capacity of the cartridge. On a CLP-510 the image counter for the toner is held on the chip on the cartridge (which also identifies the capacity of the cartridge).

There have been some faulty (oiginal Samsung chips), and of course re-manufactured cartridge chips could fail (many re-manufacturers don' test their cartridges before dispatch, they don't have the facility to do so without starting the count on the chip (or 'bowing' the reset fuse on a CLP-500 cartridge). VERY few re-manufacturers can test these cartridges without starting the count.

Sometimes the 'replace xxxxx toner' messages are caused by toner on the three contacts on the side of the cartridge, or their mating contacts inside the printer. Rarely, this can be caused by a faulty circuit board.
