• reapplying an electrostatic charge in a nonimagewise manner to the photoconductive portion of the support means,
• addressing a second set of microcells and at least a portion of the first set of microcells with radiant energy to which the photoconductive portion is responsive to selectively remove electrostatic charge, the second set of microcells forming an interlaid pattern with the first set of microcells, and
• introducing a second electrographic imaging composition into the second set of microcells while excluding the second electrographic imaging composition from the first set of microcells.
