摘要： Methods and apparatus for improving modularity in a micro-fluid ejection device and for providing instruction data to a plurality of data handling devices within a micro-fluid ejection device. The method includes generating device data and appending an address to the device data to generate instruction data. The address typically indicates at least one data handling device within the micro-fluid ejection device for which the device data is intended. The instruction data is provided to a plurality of data handling devices including at least one data controller. The data controller is operated to decode the address from the instruction data and select at least one data handling device to receive the device data based upon the decoded address. The device data is thereby input into each selected data handling device and subsequently used to operate the micro-fluid ejection device.

摘要： Current control circuit for micro-fluid ejection heaters. In one embodiment, the current through a heater in a micro-fluid ejection device may be monitored and regulated to maintain a particular value or range of values. In such an embodiment, the heater current may be monitored and compared to a reference value. A signal may be induced based upon the divergence of the beater current from the value and the signal may be applied to the logic switch for the monitored heater. The logic switch may regulate the current through the heater based upon the induced signal. As a result of the regulation of the current, the induced signal may dynamically change thereby allowing fast regulation of the heater current.

摘要： A micro-fluid ejection device, such as an inkjet printhead, includes a substrate, a heater chip on the substrate, a structure on the substrate for supplying ink to the heater chip and a nozzle plate on the heater chip. The heater chip has a plurality of electrically-activatable spaced apart heater elements that can be repetitively subjected to momentary electrical activation and deactivation so as to cause cyclical heating and cooling of ink in the heater chip resulting in repetitive ejection of drops of ink by the nozzle plate on the heater chip. The device also includes a thermal control system in the heater chip being self-managed by operation of a control loop defined by the thermal control system internally of the heater chip and substrate for sensing and limiting the variation of the temperature of the substrate during cyclical operation of the heater elements of the heater chip.

摘要： An apparatus provides identification information related to at least one ink jet print head in an ink jet printer. The apparatus includes a printer controller for providing a first identification data string comprising n number of bits, at least one of which has a first state, and no more than n−1 number of which have a second state different from the first state. Coupled to the printer controller is a first ink jet print head having a first serial input shift register. The first serial input shift register has at least n number of bit positions for receiving the n number of bits of the first identification data string. The first ink jet print head also includes at least n number of first latches, each of which is coupled to a corresponding one of the n number of bit positions of the first shift register. The n number of first latches are for latching the n number of bits of the first identification data string from the n number of bit positions of the first shift register. A first identification line, which is coupled to a predetermined one of the first latches, provides to the printer controller one of the n number of bits from the first identification data string that is latched into the predetermined one of the first latches. Based upon whether the bit provided on the first identification line has a first or second state, the printer controller determines whether the first print head is of a first type.

摘要： Disclosed is a method for compensating a shift in an ON resistance of a transistor in a chip of a printhead of an inkjet printer. The method includes determining a value of a life indication parameter of the printhead and comparing the determined value of the life indication parameter of the printhead with at least one predetermined value of the life indication parameter. The at least one predetermined value of the life indication parameter of the printhead is stored in at least one of a memory of the inkjet printer and a memory of the chip of the printhead. Thereafter, a gate voltage input to the transistor is modified based on a difference between the determined value of the life indication parameter and the at least one predetermined value of the life indication parameter of the printhead for compensating the shift in the ON resistance of the transistor.
