By Targeted News ServiceALEXANDRIA, Va., Oct. 31 — Lexmark International, Lexington, Kentucky, has been assigned a patent (8,873,996) developed by two co-inventors for a "[t]oner system for an image forming device including a toner cartridge having a shutter with bypassing actuation."

Toner system for an image forming device including a toner cartridge having a shutter with bypassing actuation
Abstract
A toner system according to one example includes a developer unit and a toner cartridge. The developer unit includes a toner reservoir, an inlet port and a shutter. The toner cartridge includes a toner reservoir, an outlet port and an engagement member having a first engagement surface and a second engagement surface. The first engagement surface is positioned to receive an actuation force from a feature of an image forming device. The second engagement surface is positioned proximate the outlet port to engage the shutter of the developer unit. The engagement member is movable from a first position to a second position upon receiving the actuation force. As the engagement member moves from the first position to the second position when the toner cartridge is mated with the developer unit, the second engagement surface protrudes from the front of the toner cartridge and opens the shutter of the developer unit.
The patent application was filed on June 17, 2013 (13/919,021). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8873996.PN.&OS=PN/8873996&RS=PN/8873996
