I have bought this toner over a year ago. Now more than ever eased the print quality, the usual message came - Toner Low. I only imagined doing nothing - is just so ... but now saw that I have the cartridge until just over one year. I print mainly bills or even a letter, but no photos, etc. Also on my paper consumption I can see very well that I max. 1200 sheets have consumed this year. If it would have meant "Toner is enough for 1,500 sheets" I had not said anything, but this is much too deep below expectations.
