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： An n-bit serial shift register in an ink jet print head operates in a print mode or a test mode. When the shift register is operating in the print mode, n bits of print data are serially scanned into n number of bit registers and are then latched out to heater addressing logic circuitry in the print head to control a print operation. When the circuit is operating in the test mode, x bits of test point data from x number of test nodes in the print head are loaded in parallel into x number of the n number of bit registers, and are then serially scanned out to a test data output. In this manner, a single shift register may be used to scan in print data and scan out test data, thereby providing observability and controllability of the internal logic nodes of the print head while minimizing logic size and the number of input/output connections on the print head.

摘要： An inkjet printhead heater chip has an integral voltage regulator that derives two output voltages from a single chip input voltage. One of the two output voltages powers control logic circuitry as the other powers FET drivers. Preferred output voltages include +3.3 volts for the control logic circuitry and +7.5 volts for the FET drivers. A Vgs of the FET is about +7.5 volts which enables a FET area width of about 400 microns. Outputs of the control logic circuitry provide input to the FET drivers. A resistive heater for ejecting ink couples between a drain of the FET and the chip input voltage. Voltage regulating capacitors exist on the heater chip in parallel with the input voltage and each of the output voltages. Preferred capacitors have a gate oxide and a polysilicon layer overlying a substrate. Inkjet printers for housing the printheads are also disclosed.

摘要： An ink jet printer includes a printhead control circuit that produces printhead command signals based on data signals provided by the printer. A power circuit actuates ink ejectors in response to the printhead command signals and includes a plurality of compensation circuits. Each ink ejector is associated with a single compensation circuit and each compensation circuit includes a number of switches connected in parallel with each other. Each switch in a single compensation circuit is connected to actuate a single ink ejector when the switch is turned on. The compensation circuits adjust their internal resistance by turning on more or less switches and thereby compensate for changing effective parasitic resistance of the power lines.

摘要： An inkjet printer includes a printhead for ejecting ink onto a print medium. The printhead includes electrical and mechanical structure for controlling the ejection of the ink. The printhead includes an ink ejector chip having at least one active device, such as a transistor and the like. A guard ring substantially surrounds select active devices included on the chip. The guard ring tends to prevent latch-up when the chip operates to energize the ink. The chip is manufactured using a substrate devoid of an overlying epitaxial layer which tends to reduce the cost of manufacturing the chip.

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： 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.
