Abstract
Process for compensation of mechanical defects in an ink jet printer in which the ink viscosity, the jet velocity, the distance at which the ink jet is broken into droplets and the phase are independently servocontrolled to respect set values, process according to which the droplet arrival position is compared with a reference position, and mechanical defects are compensated by varying the electrical charge on the droplets. The invention also relates to a printer equipped with checking and servocontrol means so that compensation according to the process can be applied. The mechanical assembly of the printer will thus be simplified.
