Abstract
A printer for printing to electrically printable media is described. During printing, a drum surface having first and second portions is charged to a first voltage, and the second portions of the surface are selectively discharged. A transfer electrode has a uniform voltage applied thereon. A first erase electrode and a second erase electrode have a fixed voltage differential between them. The printer receives the electrically printable medium between the first erase electrode and the second erase electrode to expose the electrically printable medium to the fixed voltage differential, and to move the electrically printable medium proximal to the drum and the transfer electrode to expose the electrically printable medium to a first voltage differential that results from the first voltage of the first portions and the uniform voltage, and a second voltage differential that results from the second voltage of the second portions and the uniform voltage.
