Abstract:
1. A liquid cartridge determination system, comprising: a liquid cartridge comprising: a mounting portion configured to receive the liquid cartridge thereon, wherein the liquid cartridge is configured to be inserted into the mounting portion in the particular direction; a first detector configured to detect the first detect portion when the liquid cartridge is positioned in a first position relative to the mounting portion, and to generate a first signal when the first detector detects the first detect portion; a second detector configured to detect the second detect portion when the liquid cartridge is positioned in a second position relative to the mounting portion, wherein the first position is different than the second position, and to generate a second signal when the second detector detects the second detect portion; and a determiner configured to determine whether the liquid cartridge has at least one predetermined characteristic associated therewith based on a time difference between a first time when the first signal is generated by the first detector from detecting the first detect portion and a second time when the second signal is generated by the second detector from detecting the second detect portion.
