Abstract
A printhead includes a plurality of recording elements such as LEDs each having a light output characteristic related to a driving parameter such as current. A plurality of driver circuits establishes the driving parameter for driving the recording elements. The driver circuits are mounted on a circuit board. A flex circuit having a conductive pattern electrically connects the driver circuits to the recording elements. The driver circuits include resistors for use in regulating the driving parameter. In lieu of mounting the resistors on the circuit board, the resistors are instead advantageously mounted on the flex circuit for controlling current to the respective recording elements. This allows the resistors and recording elements to be replaced without the need to also replace or modify the circuit board in the event that more efficient recording elements are to be used.
