Print sequence in an electrophotographic printer

An electrophotographic printer comprising:

• a photo imaging member;
• at least one image development unit to develop first and second images by depositing respective first and second sequences of color separations onto the photo imaging member;
• an intermediate transfer member having a first portion to receive the first sequence of color separations from the photo imaging member and a second portion to receive the second sequence of color separations from the photo imaging member;
• a voltage source to selectively apply a voltage to the intermediate transfer member;
• and
• a controller to:
• control the voltage source such that the intermediate transfer member receives each color separation from the photo imaging member;
• insert at least one null separation into the second sequence of color separations during the development of the second image;
• and
• during a period for the null separation, control the voltage source to:
• reduce a voltage applied to the intermediate transfer member, and
• transfer the first image to a conductive substrate,
• wherein the controller is provided to transfer the first image to the conductive substrate when a subset of the second sequence of color separations have been received on the second portion of the intermediate transfer member.

A non-transitory computer readable storage medium comprising a set of computer-readable instructions stored thereon, which, when executed by a processor, cause the processor to, in an electrophotographic printer:

• receive print data for at least a first image and a second image to be printed to a conductive substrate;
• instruct development of the first and second images by depositing color separations of a printing substance from at least one image development unit onto a photo imaging plate of the electrophotographic printer;
• instruct transfer of said color separations from the photo imaging plate to the intermediate transfer member in accordance with respective first and second separation development sequences of the color separations, wherein the development sequences comprise one or more null separations to delay development of the second image;
• and
• during the one or more null separations:
• instruct a reduction of a voltage applied to the intermediate transfer member, and
• instruct transfer of the first image from the intermediate transfer member to a conductive substrate,
• wherein the transfer of the first image to the conductive substrate occurs when a subset of the coloration separations of the second separation development sequence has been received on the intermediate transfer member.
