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 inkjet printhead heater chip has an ink via asymmetrically arranged in a reciprocating direction of inkjet printhead movement. The ink via has two sides and a longitudinal extent substantially parallel to a print medium advance direction. A column of fluid firing elements exists exclusively along a single side of the two sides. The heater chip and ink via each have a centroid and neither resides coincidentally with one another. Preferably, the heater chip centroid resides externally to a boundary of the ink via. In other aspects, the column of fluid firing elements can be a sole column or plural and may be centered in the reciprocating direction. The ink via can be a sole via or plural. The heater chip can be rectangular and the ink vias can be closer to either the long or short ends thereof. Inkjet printers for housing the printheads are also disclosed.

摘要： The present invention is directed toward an improved heater chip for an ink jet printer. The heater chip has a diamond-like-carbon coating that functions as the cavitation and passivation layers of the heating elements on the heater chip. To improve the efficiency of the heater chip, the diamond-like-carbon coating is surrounded by a material that has a lower thermal conductivity than diamond. This surrounding layer limits thermal diffusion from the heating elements into the heater chip. A smoothing layer of tantalum is deposited over the diamond-like-carbon layer to insure that vaporization of the ink occurs at the ink's superheat limit. The diamond-like-carbon layer is preferably less than 8700 Angstroms in thickness such that less than 1 microjoule of energy is required to expel of ink droplet having a mass between 2-4 nanograms.

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： The invention described in the specification relates to an apparatus for supplying electrical information to a printer controller in order to identify the one or more cartridges installed in a printer. The apparatus comprises a carriage which is laterally translatable relative to the movement of print media through the printer, carriage translation means, and a replaceable cartridge attached to the carriage. The apparatus further comprises an indicia device which is attached to the replaceable cartridge and which has optically readable indicia thereon containing encoded information which contains information identifying the type of cartridge installed in the printer. The apparatus also includes an optical code reader which reads and transmits the encoded information to a printer controller as the cartridge moves in a lateral direction relative to the code reader. The invention thus uses the linear motion of the carriage in combination with the optically readable indicia device on the cartridge to identify the type of cartridge, or to otherwise control the printer depending on the specific information provided by the indicia device.

摘要： An ink jet print head identification system for providing print head identifying information to the electronics of an ink jet printer includes one or more parallel load, serial out, dynamic shift registers integrated into a print head chip having a plurality of address lines interconnecting the printer electronics and the print head electronics. The memory input of each shift register is electrically connected to a memory matrix that supplies digital bits of information to the shift register in response to receiving a decode signal function from the printer electronics. In a preferred embodiment, two of the address lines provide each of the registers with successive sequential clock signals to serially shift the bit of information received from the shift register's corresponding memory matrix to an output line where the print head identifying information is read by the printer electronics. Embodiments of the invention may employ any number of shift registers and memory matrices independent of the number of available address lines.
