摘要

A magnetic deflector for a magnetic ink jet printer has compensating pole pieces which alter the gradient field produced by deflection pole pieces so as to counterbalance centering forces acting on magnetic ink drops moving through the magnetic field in off center locations. The compensating pole pieces are preferably passive and extend from the zero potential region of the magnetic circuit of the deflection pole pieces.
