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： 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： A print data loading circuit receives N bits of serial data on a serial input data line, and provides the input data to a data bus in an addressing circuit for addressing one or more image-forming elements in a printing device. The data loading circuit includes an N-bit serial shift register having N number of serially-coupled single-bit storage registers. The data loading circuit also includes N−1 number of data latches, each having a data input coupled to a data output of a corresponding one of the single-bit storage registers. The data outputs of the data latches are coupled to N−1 number of selection lines that are coupled to the data bus. Each data latch has a clock input that is coupled to the data output of the Nth storage register. Based on this configuration, a bit provided at the Nth-register data output acts as a load trigger bit to cause the other data bits in the other single-bit storage registers to be loaded into the N−1 number of data latches. By providing the trigger bit from the Nth register of the shift register, the present invention eliminates the need for a second clock input to latch the print data into the data latches. Eliminating a second clock input reduces print head costs and potential EMI problems.

摘要： A fluid cartridge has a bottle to retain a volume of fluid. An ejector chip resides in fluid communication with the bottle and causes ejection of fluid upon activation of fluid ejectors. Control logic coordinates ejector activation with dose control logic and temperature control circuitry. The dose control logic pre-specifies an amount of fluid to be ejected and prevents further ejection upon reaching the amount. Meanwhile, the temperature control circuit inhibits any ejection until a temperature of the fluid is within a predefined acceptable range. Bottle modularity, fluid dispense-areas and group-control of the ejectors facilitate certain designs.
