摘要： Method and apparatus is described for detecting faults, such as cracks, in ink jet printhead heater chips using a resistor on the heater chip. The resistor is located adjacent to at least one edge of the heater chip. One method, for example, includes the steps of measuring the resistance of the resistor at a first temperature and comparing the measured electrical resistance to a theoretical calculated resistance. Another method, for example, includes the steps of measuring the resistance at a first temperature, heating the chip, and measuring the resistance at a second temperature. Faults are detected by comparing expected changes in resistance or temperature to measured changes.

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： The invention provides a method for reducing ink corrosion of exposed metal layers on a chip surface of a semiconductor chip for an ink jet printhead. The method includes depositing a protective layer in a plasma process to the chip surface, the protective layer being deposited adjacent ink ejectors so that the protective layer substantially circumscribes an ink via in the chip. A thick film layer is applied to the protective layer and chip, whereby the protective layer and thick film layer are sufficient to promote increased adhesion between the thick film layer and a nozzle plate attached to the thick film layer thereby substantially reducing a tendency for the nozzle plate and thick film layer to delaminate from one another during printhead manufacture or use and interrupting contact between ink and the exposed metal layers on the chip surface.

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.

摘要： An apparatus addresses ink jet heating elements based on image data to cause ejection of ink droplets toward a print medium. The apparatus includes a controller for generating address signals, power signals, and first and second bank signals. The first and second bank signals, which are carried on first and second bank lines, alternate between on and off states. The first bank signal is off when the second bank signal is on, and the second bank signal is off when the first bank signal is on. The apparatus has m address lines and n power lines connected to the controller for carrying the address signals and the power signals. A print head has m×n number of first driver circuits, each of which is connected to the first bank line and to a corresponding one of the m address lines. The first driver circuits enable flow of a first driving current when the first bank signal and the address signal are simultaneously on on the first bank line and the corresponding address line. The print head has m×n number of second driver circuits, each of which is connected to the second bank line and to a corresponding one of the m address lines. The second driver circuits enable flow of a second driving current when the second bank signal and the address signal are simultaneously on on the second bank line and the corresponding address line. First heating elements are each connected to a corresponding one of the first driver circuits and to one of the n power lines. A first heating element is activated by the first driving current when the power signal is on on the connected power line and the corresponding first driver circuit enables flow of the first driving current. Second heating elements are each connected to a corresponding one of the second driver circuits and to one of the n power lines. A second heating element is activated by the second driving current when the power signal is on on the connected power line and the corresponding second driver circuit enables flow of the second driving current.
