Xerox Hoping For A Monochrome Revolution

The DocuTech Copier/Printer uses ultrasound waves to detect whether or not pages are stuck together. Wide-radius turns in the paper path help avoid scuffing and scratching. They also support heavier stocks.

A Toner Cloud

Toner and developer are mixed in the toner canister and are delivered together. The toner is suspended in a cloud so that no toner touches the photo receptor, extending its life. (The receptor is also brush- and vacuum-cleaned so toner from one page doesn't get onto the next page.)
