摘要： A method for determining the pulse width for driving printhead nozzles in a thermal inkjet printer. The printhead is preheated to a desired temperature during a maintenance mode. The printhead nozzle heaters are successively driven in respective heating intervals, where each successive heating interval is characterized by shorter drive pulse width pulses occurring at a higher pulse frequency. The printhead temperature data received during each heating interval is processed to determine a respective temperature slope. The temperature slopes are compared to a desired threshold temperature slope, and when a match is found, the pulse width associated with the matched temperature slope is used to drive the nozzle heaters during subsequent printer operations to print characters on a print medium.

A flowpath delivers ink from the ink source to the heater and is defined at least in part by the mounting base on the body. Three or more thermally conductive paths extend from the mounting base to the body. Preferably, one or more of the thermally conductive paths are heat conductive bridges extending from the mounting base to the body through an edge feed via.

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.
