I have heard that when you buy printers (either laser or inkjet), the cartridge/toner that they give you isnt the full sized version. Yesterday I bought the Samsung CLP-315 (its a laser printer). http://www.trustedreviews.com/printers/review/2008/09/16/Samsung-CLP-315-Colour-Laser-Printer/p1 So im assuming that the toner will not last as long enough I do know that toners for laser printers are supposed to last for a long time, though. Can anyone give me a rough estimate as to how long (or, how many pages approximatey) can i get out of the black toner that already comes with the product? A normal full-sized black toner is supposed to do 1000 pages of text (I called the Samsung helpline yesterday). To make a sensible estimation, am i along the right lines to say that the already-supplied black toner will last me 500 pages? I don’t even know if the toner theyve given me is smaller-sized or whether it is in actual fact the real and full-sized thing. I did open up the printer and quickly had a look. The reason why im asking is because i originally bought this laser printer so that i can sit in my room and keep printing off draft copies of my university project (It saves me having to travel into uni every day to use the printer there). Im a bit worried now, though, because knowing my luck, after printing off draft copies of my essay. i bet the toner will run out the day before i have to hand in my work... Please can someone help me :( and if you know anything about laser printers please can you write something just so that I am put at ease!! Thanks for all the responses so far. I have looked and this is what it says on the black toner: CLT-409 (Series E) UNIT - DEVE BLACK S/N: CNE1JC9604755ABP3AQAP1990 So im assuming CLT-409 (Series E) is the part number. I FOUND THE ANSWER! I called them up. They said that the already-supplied toners contain 1/3 ink, so I should be able to get approx. 700 pages (when printing at 5% coverage)
