Copier Printer Scanner Features - Terms and Accessories?

The copier printer all in one industry has changed over the past three years. What use to be options now comes standard accessories on many copier models. If you plan to lease a copier or purchase a copier printer all in one it's important to know the features and what you actually need for your office equipment. What is an ADF or DADF (automatic document feeder or double-sided automatic document feeder)? The ADF or DADF sits on the top of the copier printer scanner and gives you the ability to automatically feed a stack of papers to copy, fax out or scan to a computer. Some brands of copiers still call this an option. However, a machine never goes out the door without this. Usually the feeder allows up to 50 pages (some up to 100 pages) at one time; on your digital copier or multifunction printer.
