Abstract
The detection system includes a cartridge having a first detection port for detecting the pressure condition in the top portion of the cartridge and a second detection port and tube for detecting the pressure condition in a bottom portion of the cartridge. The cooperative printer structure couples these ports to a pressure differential sensor that signals a printer refill condition.
