Abstract: An electrical connector having a housing with at least one contact receiving passageway extending from an insertion face to a mating face. The contact receiving passageway has a wall extending about the perimeter of the contact receiving passageway. A contact is insertable into the contact receiving passageway from the insertion face toward the mating face. The contact has a mounting portion positioned in the contact receiving passageway. The contact has a lance which extends outward from the mounting portion. A recess extends from the contact receiving passageway into the wall of the contact receiving passageway. The recess has a stop surface and a lead-in surface. The lance cooperates with the stop surface of the recess to properly position and retain the contact in the at least one contact receiving passageway.

Abstract: A driver chip for use in an LED or other multi-element recording printhead includes a plurality of current driver channels. Data for determining recording durations for each of the current driver channels is provided on a data bus. A token bit is shifted through a shift register in association with image data to be latched by registers corresponding to a specific driver channel. The driver chip is operational in different recording resolution modes so that it may be connected to recording arrays of different resolutions. When operational in other than its highest or higher resolution, a by-pass signal is generated causing the token bit to by-pass certain stages of the shift register.

Abstract: A non-impact printhead having a plurality of driver IC chips and and a plurality of recording elements such as LEDs. Each driver IC chip includes a plurality of current-carrying channels that are operative for carrying current to respective recording elements on the printhead and a control for controlling operation of the driver.

Abstract: In an LED printhead or the like, a plurality of LED arrays are arranged in a row. Opposite the LED arrays are driver IC chips providing current in respective current driving channels to respective LEDS. Current to an LED for recording of a pixel will be provided for say a duration related to a multibit image data signal. A data bus is provided for carrying the data signals. The data signals are latched in respective data registers associated with each current driving channel. A token bit shift register is provided for identifying a respective data register for latching of the multibit image data signal presently on the data bus. A direction of shifting of the token bit is determined through automatic self-sensing of the token bit itself as the token bit is moved from a boundary scan register that forms a part of a boundary scan test architecture.
