I bought an inexpensive copier a few years ago for occasional use. The copier is great, but soon found out that the toner is more expensive than the printer. I shake the toner until every drop of ink is out of the cartridge before changing it. The product that I bought (Black Toner E20 for Canon Copier) was brand new plus actually was manufactured by Canon and not an immitation cartridge. It was a great price. The seller was very prompt. The item was exactly as he described.
I use my Canon copier daily and welcome bargain prices for a genuine toner. This product costs twice as much when I have to buy it at an office supply store. Thanks to Ebay I can save a little money on my supplies.
The toner last for about a 5000 copies. Is good for the home or small business. I have a small busness and I have to buy a new toner every 4-6 months. I have an other copier that last only a month and that toner only good for 1000 copy.
