From my experience NONE of the laser printer manufacturers are filling their cartridges BECAUSE they want to sell you MANY more cartridges! One supplier seems to have decided to fight the manufactureres by filling cartridges to their REAL capacities: checksnet.com
Dell puts about 80grams of toner in a 1700 cartridge. Checksnet.com claims to put 250grams in their triple filled cartidge. I took a chance and ordered one. It must be true because I've printed thousands of pages and like that energizer bunny ... it just keeps going.
really didn't need the ability to print checks (MICR) but this toner also seems a bit darker than regular toner so I've also lowered the toner darkness so this thing may last forever!
