TRANSITIONAL INK JET HEATER ADDRESSING

摘要

An apparatus addresses ink jet heating elements based on image data to cause ejection of ink droplets toward a print medium. The apparatus includes a controller for generating address signals (316a-316m), power signals (318a- 318h), and first (314a) and second (314b) bank signals. The apparatus has m address lines and n power lines connected to the controll for carrying the address signals and the power signals. A print head has m x n number of firs t driver circuits, each of which is connected to the first bank line and to a corresponding one of the m address lines. The print head has m x n number of second driver circuits, each of which is connected to the second bank line a nd to a corresponding one of the m address lines. First heating elements are ea ch connected to a corresponding one of the first driving circuits and to one of the n power lines. Second heating element are each connected to a corresponding one of the second driving circuits and to one of the n power lines.
