Ink jet printer with artifact-reducing drive circuit

An ink jet printer, comprising:

• at least two print heads fabricated of non-identical semiconductor material and each having a plurality of ink jets residing on an exterior surface thereof, wherein each of said at least two print heads possesses a set of different electrical properties from the other of said at least two print heads;
• an EEPROM electrically coupled to one of said print heads, wherein said EEPROM is programmed to store an information set for each of said plurality of ink jets that are related to said set of different electrical properties of the one of said print heads;
• a power supply source for receiving the information set for each of the plurality of ink jets from the EEPROM and applying an ideal jet driving power signal to said at least two print heads and thereby created a compensated firing signal for each of said plurality of ink jets which, if applied to said at least two print heads would generate an emitted series of ink droplets of an ink marking material of the same volume of the ink marking material from each of said plurality of ink jets;
• an image signal source for selectively activating each of the plurality of ink jets for firing a portion of the plurality of ink jets based on a digital image data set;
• and
• an artifact reduction circuit electrically coupled to the ideal jet driving power signal to selectively alter the power signal in a pseudo-random manner for each of said at least two print heads;
• wherein the artifact reduction circuit alters a voltage of an ideal jet driving power signal and wherein the artifact reduction circuit comprises a noise generator which creates a low voltage noise signal and the low voltage noise signal electrically coupled to the ideal jet driving power signal via an electrical amplifier.
