Systems, Methods and Apparatuses for Authorized Use and Refill of a Printer Cartridge

A chip for a cartridge with dispensable material, comprising:

• a non-volatile memory for storing a number tracking amount of dispensable material in the cartridge with dispensable material;
• a circuit configured to detect changes in an environmental parameter;
• and
• circuit components configured to:
• receive a first message comprising a first command and an operation input value for a print job at the cartridge;
• process the first message, comprising decreasing the amount of dispensable material in the cartridge;
• receive a second message comprising a second command to increase the amount of dispensable material;
• and
• ignore the second command when the circuit has detected changes to the environmental parameter beyond permissible bounds to prevent responding to requests to increase the number tracking amount of dispensable material.

A method for performing operations by a chip of a cartridge with dispensable material, comprising:

• receiving a first message comprising a first command and an operation input value for a print job at the chip;
• processing the first message, comprising decreasing a number tracking amount of dispensable material in the cartridge, the number being stored in a non-volatile memory of the chip;
• receiving a second message comprising a second command to increase the amount of dispensable material;
• detecting changes in an environmental parameter with a circuit of the chip;
• and
• ignoring the second command when the circuit has detected changes to the environmental parameter beyond permissible bounds to prevent responding to requests to increase the number tracking amount of dispensable material.
