INK JET PRINTER APPARATUS AND METHOD OF PRINTING

摘要

INK JET PRINTER APPARATUS AND METHOD OF PRINTING 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.
