摘要： A system is described for compensating for misalignments in an ink jet printer having an ink jet print head cartridge that includes a heater chip. The system includes determining alignment adjustment information related to the misalignments in the ink jet printer, loading the alignment adjustment information into a volatile memory device on the heater chip, and accessing the alignment adjustment information from the volatile memory device. The system also includes generating nozzle control signals based at least in part on the alignment adjustment information. The nozzle control signals are selectively provided to resistive heating elements in the heater chip, thereby heating ink in ink chambers adjacent the heating elements and ejecting ink droplets toward a print medium. The timing of the nozzle control signals is adjusted based upon the amount of misalignment in the various components of the printer and print head. The timing adjustments are applied to groups of nozzles so that dots printed by one group are substantially vertically aligned with dots printed by another group, thereby reducing the amount of perceptible skew in the printed output.

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： A thermal ink jet printing apparatus maintains stable printing output as certain characteristics of the apparatus change over its operational lifetime. The apparatus includes an ink jet print head with resistive heating elements for receiving electrical energy pulses having a voltage level and for transferring heat energy pulses having a desired energy level into adjacent ink based on the electrical energy pulses. The print head includes nozzles associated with the resistive heating elements through which droplets of the ink are ejected when the heat energy pulses are transferred into the ink. The apparatus further includes a printer controller in electrical communication with the print head. The printer controller determines a pulse count indicative of a number of electrical energy pulses, applies the electrical energy pulses having a first pulse width to the resistive heating elements when the pulse count is less than a threshold value, and applies the electrical energy pulses having an adjusted pulse width to the resistive heating elements when the pulse count exceeds the threshold value. The difference in the first and the adjusted pulse widths compensates for changes in the electrical resistance of the resistive heating elements over time.

摘要： The invention relates to a method and an apparatus for firing the nozzles on an ink jet print head cartridge that requires a reduced number of data lines between the ink jet print head cartridge and the printer electronics. A group data line provides serial group select data that is stored in a set of group select latches on the ink jet print head cartridge and identifies a particular group of nozzles on the ink jet print head. A primitive data line provides primitive select data that is stored in a set of primitive select latches on the ink jet print head cartridge and identifies a particular nozzle in the selected set of nozzles. A first clock line provides a first clock signal that is used to advance the group select data and the primitive select data into the group select latches and primitive select latches respectively. The group select data and the primitive select data is decoded to produce firing data which is advanced to a set of firing latches in accordance with a second clock signal that is provided on a second clock line. The data in the firing latches is logically ANDed or NANDed with a firing pulse provided on a firing line in order to expel a drop of ink from the selected nozzle or nozzles on the ink jet print head cartridge.

摘要： An ink jet print head is controllable based at least in part on q number of first control signals and p number of second control signals. The print head includes a print head integrated circuit chip having ink-heating resistors for generating heat when activated. The print head chip also has a switching circuit for receiving the first and second control signals, and for selectively activating the resistors by allowing electrical current to flow through selected resistors based at least in part on the first and second control signals. The switching circuit is operable in either a first operating mode or a second operating mode, where q is equivalent to q1 in the first operating mode, and is equivalent to q2 in the second operating mode, and where q1 is twice q2. In the first operating mode, p is equivalent to p1, and in the second operating mode, p is equivalent to p2, where p2 is twice p1. The product of q1 multiplied by p1 is equivalent to the product of q2 multiplied by p2. The print head also includes an operating mode selection circuit connected to the print head integrated circuit. The configuration of the operating mode selection circuit determines whether the switching circuit operates in the first operating mode or the second operating mode. When in the first operating mode, the print head requires four passes across a print medium to completely print an image, while in the second operating mode, the print head requires only two passes. Thus, a print head implemented according to the second operating mode offers a higher performance design point. However, a print head implemented according to the first operating mode is less expensive to manufacture. Therefore, the invention provides a single print head integrated circuit chip which may be used for two different cost/performance design points, the selection of which depends upon the configuration of the operating mode selection circuit.

摘要： An ink jet print head includes a nozzle plate having a substantially linear array of ink jet nozzles through which ink droplets are ejected toward a print medium. An integrated circuit chip, which is disposed adjacent the nozzle plate on the print head, includes a semiconductor substrate, a source voltage conductor connected to a source voltage, and a ground return conductor. A substantially linear array of ink heating resistors are disposed on the substrate substantially parallel to the length of the chip, each associated with a corresponding one of the ink jet nozzles. The chip also includes a plurality of substrate heater resistors disposed on the substrate in a substantially linear arrangement and aligned substantially parallel with the nozzles. The substrate heater resistors are electrically connected in parallel, with one node of each being connected to the source voltage conductor and another node of each being connected to the ground return conductor. Preferably, the substrate heater resistors include first substrate heater resistors disposed near a lengthwise center of the chip and second substrate heater resistors that are distally disposed relative to the lengthwise center of the chip. The first and second substrate heater resistors have different first and second electrical resistance values, respectively, that are determined by thermal dissipation patterns of the chip. The difference between the first and second electrical resistance values cause the first and second substrate heater resistors to generate different amounts of heat when supplied with the source voltage. The different amounts of heat generated by the first and second substrate heater resistors and the relative positions of the first and second substrate heater resistors compensate for differing thermal dissipation patterns across the chip.
