Abstract
An ink jet printer apparatus and method using ink carrying magnetizable particles, the ink being passed as a stream of droplets sequentially through an electromagnetic field and an electrostatic field, in that order. The droplets are selectively charged electrostatically. All drops are subjected to a time dependent magnetic flux field which effects scans of the drops at a recording surface. Drops not to be used are deflected by electrostatic deflection plates to a gutter.
