To really ensure that you are getting the best out of your AcuLaser C9100 laser printer, it is important to make sure that it is properly maintained. Sometimes toner is going to be wasted and if this is allowed to accrue in your machine, it can cause problems. Epson understands that you deserve a brand that is going to support all aspects of your printing. It has produced this waste toner collector to ensure the quality of your prints and avoid damage to your printer. It's designed to store waste toner from up to 24,000 pages.
