Ink level detection within ink cassette used in a printer is based upon measured pressure difference fed to built in processor |
摘要 |
The ink jet printer has an air pressurized (115) ink supply cassette (114) that delivers ink to the print head (120). A differential pressure sensor (131) monitors the difference between air and ink lines (122,113) and a processor (134) computes the volume of ink remaining in the cassette.
