Replaceable cartridge, kit and method for flushing ink from an inkjet printer

A kit for use with an inkjet apparatus in which a reservoir cartridge with a first ink has been installed, said kit comprising:

• a replaceable reservoir cartridge comprising:
• a supply of fluid for flushing said first ink from pathways in said inkjet apparatus;
• and
• a memory that couples to a processor in said inkjet apparatus upon installation of said replaceable reservoir cartridge therein, said memory including flush control parameters which, upon being accessed and utilized by said procedure, provide a notice to a user of said installation of said replaceable reservoir cartridge and that a fluid other than said first ink has been installed, and enable said user to selectively cause a printing of a plurality of media sheets through use of said fluid to enable a flushing of said first ink from said pathways;
• and
• a storage media with a procedure for controlling said inkjet apparatus upon installation of said replaceable reservoir cartridge thereinto.

A method for changing ink in an ink jet printer from a first ink to a second ink, said ink jet printer including a processor, a printhead mounted on a carriage, a fluid conduit with an inlet end and an outlet end in fluid communication with the printhead, and a first cartridge containing said first ink that is in fluid communication with the inlet end of said fluid conduit when it is releaseably mounted in a fixed supply station, the first ink initially resident in said printhead and said fluid conduit, said fist ink cartridge including a first memory for containing at least a first ink parameter and having a first cartridge electrical connector that contacts an electrical connector to couple said first memory with said processor, said method comprising:

• providing a second cartridge that contains a supply of a fluid for flushing said first ink from said fluid conduit, said second cartridge including a second memory for storing at least a fluid parameter comprising a flush control parameter and including a second cartridge electrical connector;
• decoupling said inlet end of said fluid conduit from said first ink cartridge and said first cartridge electrical connector from said inkjet printer;
• coupling said inlet end of said fluid conduit to said second ink cartridge;
• coupling said second cartridge electrical connector to said inkjet printer;
• transmitting said fluid parameter to said processor and providing a notice to a user of installation of said second ink cartridge and that a fluid other than said first ink has been installed;
• selectively enabling said user to enter a command;
• upon entry of said command by said user, providing energization signals in response to said fluid parameter to said printhead in said inkjet printer such that said printhead ejects fluid onto media while the carriage scans;
• and
• channeling said fluid from said second cartridge to said printhead while providing said energization signals to said printhead until said fluid substantially replaces said first ink in said fluid conduit and said printhead.
