MM04

MM04 is an inkjet print head driver intended for use with the Ricoh GEN5 print head. The module contains an analog and a digital section. The analog section consists of four independent power amplifiers, each of which is capable of producing the fire pulses needed to drive up to 1280 inkjet nozzles. The digital section uses 3-bit, digital printing data for the print head’s output latches, and generates exactly timed analog input signals for the power op amps. The analog section plugs into the digital section and is built on a thermally conductive but electrically insulating substrate that can be mounted to a heat sink. The digital section has a card edge connector for connection to a digital printing control system, and a side connector that accommodates the print head flex cable.
