2pk High Yield Toner Cartridge

I replaced the Linkyo toner after 2,713 pages. Considering 2600 is the advertised yield, I think this cartridge did very well. I did have a couple "Toner is low" messages pop up on the monitor. However resetting the cartridge through the on line printer interface got another couple hundred sheets printed. UPDATE: 7/12/2016 Adding additional info after testing over time. I replaced the TN450 cartridge with another LINKYO compatible on 11/5/15. AT that time my printer had printed 17837 pages. Next toner replacement was on 3/1/2016 and the printed page count was at 20550. So the LINKYO toner produced 2713 pages. Next toner replacement was on 7/12/16. Again put a new LINKYO toner in the printer and documented page count at 24290. So this time I got 3740 pages from the toner cartridge. I did deal with 3 "error" messages over this time indicating the toner needed replacement however I reset the machine 3 times using the following method (found by Googling "reset toner brother 2270"): [...] If your TN2230 – TN2250 toner counter on your HL-2130 HL-2240D HL-2250DN or HL-2270DW doesn’t reset when you install the cartridge, you may wish to try this procedure. Open the front cover and leave open while completing the following steps. Turn the printer off. Hold the ‘go’ button (or “start’ button) while turning the printer on. All panel lights should be on. Release the ‘go’ button (or “start’ button). Press the ‘go’ button (or “start’ button) 2 times. Pause. All panel lights should be on. Press the ‘go’ button (or “start’ button) 5 times. The toner light should be off (the error light may be flashing). The paper light should be on or flashing. Close the cover. The ready light should be the only light on. Note: This procedure has been tested on the HL2130 HL2240D HL2250DN and HL2270DW printer but may work on other printers using the TN2250 toner. I just now noticed print fading so after 3740 pages its time to replace the toner.
