Ink cartridge, detection device for cartridge identification and ink level detection, and image formation apparatus comprising thereof

Image Number 13 for United States Patent #7360858.

The ink cartridge has a first detection target portion for detecting ink level and a second detection target portion for identifying the type of an ink cartridge. The ink level detection device uses an optical sensor to scan the first and second detection target portions of the ink cartridge, and detects ink level and the type of the ink cartridge, that is, whether the ink cartridge is containing standard amount of ink or large amount of ink. Therefore, the number of image formation on recording media can be estimated, and failure in image formation due to a shortage of ink in the middle of image formation can be inhibited.
