We print a study guide magazine for our non-profit language school. We use 40 or 50 cartridges a year. All the toners we order from V4INK are great for us. We receive at least 1200-1500 copies of each cartridge. To be honest I don't count exactly. I weigh each cartridge to track when I expect to run out of ink. This way I can get the best out of every cartridge. If I were to rely on the copier's toner status message to change the cartridge, I would be wasting a lot of ink :) All my copies come out clean, with no streaks or dirty side lines like some other vendors. and I've tried a lot! Each cartridge cost me somewhere between $7.50 and $9.00. I return empty cartridges to Office Depot for recycling. They give you $2 as a reward which you can spend like cash :)
