Abstract: Systems and methods for identifying a device using a programmable memory circuit having at least one partially blown fuse are described herein. An electronic controller is configured to determine a resistance associated with a partially blown fuse in a programmable memory circuit and to determine an identifier based on the resistance.

Abstract: Systems and methods for identifying a device using a programmable memory circuit having at least one partially blown fuse are described herein. A fluid ejection apparatus includes an electronic controller. The electronic controller is configured to determine a resistance associated with a partially blown fuse in a programmable memory circuit and to determine an identifier based on the resistance.

Abstract: A printing apparatus includes one of a first cartridge or a second cartridge. The first cartridge has a first contact array including a plurality of contact areas. The second cartridge has a second contact array including a plurality of contact areas. The locations of the contact areas of the first contact array are different from locations of the contact areas of the second contact array. The printing apparatus further includes a carriage that interchangeably receives the first cartridge and the second cartridge. A controller identifies whether the first cartridge or the second cartridge is installed in the carriage.

Abstract: A nozzle tape covers substantially all of an outlet portion and an electrical contact portion of a print cartridge. At least one hole provided in the portion of the nozzle tape covering substantially all of the electrical contact portion exposes at least one electrical contact formed on the electrical contact portion. When the cartridge is installed in a print device, such as a printer, a partial electrical connection will be established between the exposed electrical contact and a corresponding electrical contact in the print device. The partial electrical connection may be used to convey a signal to an output device, such as a computer. The signal may indicate that the nozzle tape must be removed before the print cartridge will work properly.

Abstract: Embodiments of the invention involve modifying non-volatile data fields in the integral memory components of consumable cartridges (and, in some embodiments, data fields in the utilizing device memory) such that the consumable cartridges become compatible with only a small subset of utilizing devices, thereby substantially reducing their potential value to a thief or unauthorized borrower.

Abstract: A print cartridge includes a cartridge body having a lower portion and a vertical wall. A printhead is coupled with the lower portion of the cartridge body. A contact array including a plurality of contact areas is disposed on the vertical wall. The contact array is one of at least two contact arrays. Each contact array has a different pattern of contact area locations. A portion of the contact areas of each contact array are capable of providing identity information for the print cartridge.

Abstract: Systems, methods, and devices are provided for printhead calibration. A method includes printing a swath. A temperature rise of a printhead is measured during the swath and an operating energy of the printhead is calibrated based on the measured temperature rise while performing a non-test print job.
