Abstract

Magnetically responsive material can be used to extend the field from rotating magnets located inside a stationary cylindrical shell. The use of such a material interposes a large gap between the magnets and outer surface of the stationary shell to allow for the integration of circuity on the shell without interruption of magnetic processing. This is particularly advantageous in magnetostylus printing where print styli circuitry is required to be located in the styli area without blocking toner propagation. In the figure, the fields of rotating magnets 1 of an imaging station 2 have been extended by magnetically responsive material 3 over an arc of the stationary shell 4.

Integrated Magnetostylus Print Head and Toner Transport System

Magnetically responsive material can be used to extend the field from rotating magnets located inside a stationary cylindrical shell. The use of such a material interposes a large gap between the magnets and outer surface of the stationary shell to allow for the integration of circuity on the shell without interruption of magnetic processing. This is particularly advantageous in magnetostylus printing where print styli circuitry is required to be located in the styli area without blocking toner propagation. In the figure, the fields of rotating magnets 1 of an imaging station 2 have been extended by magnetically responsive material 3 over an arc of the stationary shell 4. Print styli 5 with associated electronics and stationary magnet 6 can now use a common substrate and be integrated using standard photolithographic techniques. The rotating magnets 1 propagate the toner 9 away from the print styli 5 area and also act as a background remover 8 by use of the magnetic material 3. The toner is then transported by the rotating magnets 1 for return to the toning station 7.
