Like most laser printers, the toner light comes on early. This gives you time to order new toner. I find it best, since it does not stop the printer from printing, just to have a toner on hand and when your toner is empty replace it. Since this is a mesurement inside the toner cartridge its self, there is no way to reset the warning (other than replace the cartridge).

If it tells you the DRUM is low it has nothing to do with toner, it probably meens you need to replace the DRUM unit (aluminium blue/green cylinder in the device) dont forget to reset the timer after replacement

Good luck!

This light is indeed designed to indicate a low toner condition. Its coming on is triggered not by the actual level of toner in the cartridge, but by a software process that estimates toner use. If you are inclined to refill your own cartridges, you can use install a glass fuse in the little clip on the back of the toner cartridge that will reset the counter, and turn out the light, otherwise the light will stay on. The reset process will blow the fuse, so a new fuse is needed each time a cartridge is refilled. Leaving the light lit does not hinder the operation of the printer, so as long as there is still sufficient toner to print, the printer will operate normally.

On the LCD display choose the 'Reset Menu'Then within that menu keep going through the (many) options 'till you get to 'Change Toner K' (K for black, C for Cyan, M for magenta,Y for yellow).
Once you select the appropriate Toner it will rotate to offer the toner for replacing.
Open up the cover at the front, reach inside and change the position of the coloured part of the toner cartridge on the R/H side to the Unlock symbol and then ease the cartridge out. It comes out at a slight angle as the part you move to unlock it comes out slightly ahead of the other side.
Put the new toner cartridge in and turn the coloured part to the locked symbol and close up.

Please take a moment to rate this solution, thanks.

There is a toner sensor in this printer that shoots a beam of light through the toner cartridge. As long as the toner is full and blocks the light, it sees it as being full. If it were the sensor, it would tell you this for all the toners, though. The printer also calculates how much toner may have been used and gives warnings based on that. It could be that this isn't getting reset after you change toner. You can reset the toner gage by going into the reset menu and selecting "New xxxx cartridge" and changing it to YES.

The symbol on top that looks like a beaker full of marbles is the symbol for the toner cartridge (notice the same symbol is found on the button that opens the toner cartridge door). If this light is on, either the toner cartridge is getting low, or the cartridge needs replaced.

Just refilling the cartridge may not resolve the low toner message. Many cartridges have a sensor chip that must be reset to clear the message. Due to this, many people opt to buy replacements or refurbished cartridges that have had the sensor chip reset.
