Method of normality decision with regard to ink cartridge and printer actualizing the method Abstract

An ink cartridge of the present invention has a storage element, in which plural pieces of specific information relating to an ink cartridge are stored at specific addresses having predetermined data lengths. For example, a piece of information on the year of manufacture is registered in a data length of 7 bits, a piece of information on the month of manufacture is registered in a data length of 4 bits, and a piece of information on the date of manufacture is registered in a data length of 5 bits. A piece of information on the time (hour) of manufacture is registered in a data length of 5 bits, and a piece of information on the time (minute) of manufacture is registered in a data length of 6 bits. The technique of the present invention determines whether the storage element incorporated in the ink cartridge is normal or abnormal, based on the piece of information on the month of manufacture. This arrangement ensures the easy and adequate determination of whether or not the information stored in the storage element is destroyed.

Method of normality decision with regard to ink cartridge and printer actualizing the method Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method of normality decision with regard to an ink cartridge, which is detachably attached to a printing apparatus like an ink jet printer or an ink jet plotter, as well as to a printer that actualizes the method.

2. Description of the Related Art

The type of ink usable for a printer generally depends upon the type of the printer, such as the ink jet printer or the dot impact printer. Byway of example, it is assumed that a certain type of ink is usable for a specific printer. If another type of ink, which has different properties from those of the certain type of ink and is not generally used for the specific printer, is mistakenly attached to the specific printer, a desired printing result may not be obtained. In another example, the ink jet printer may encounter the troubles due to a difference in viscosity of ink, such as a poor printing result or clogging nozzles on a print head. (more ink cartridges…)
