Abstract
A method and system for printing image documents using a variety of toners where some toners using a multi-development station having two or more development stations. These toners are co-printed prior to fixing, on the receiver by the multi-development station.

A method of printing using an electrophotographic print engine including a single development module that can develop a single toner on a primary imaging member of the single development module and a multi-development module that can develop either one of two toners on a primary imaging member of the multi-development module, the method comprising:
- determining a combination of toners required to form an image according to a job specification;
- determining that the combination of toners includes two toners in the multi-development module, developing and transferring first toner separations onto a receiver including a first one of the two toners in a development station of the multi-development module
- passing the receiver through the print engine a second time;
- developing and transferring a color separation using the other of the two toners in the multi-development module onto the first toner separations;
- and
- determining that the identified combination of toners does not include two toners in two development stations in the multi-development module, forming and transferring a first combination of the identified toner separations onto the receiver and diverting the receiver to at least one of an inverter and an exit.
An electrophotographic print engine comprising;
- a single development module capable of developing one toner on a primary imaging member in the single development module;
- at least one multi-development module having two development stations capable of developing one of two toners on a primary imaging member in the multi-development module;
- and
- a path that moves a receiver past the print engine and a return path that returns the receiver to the development modules;
- a control unit arranged such that the control unit determines a combination of toners required to form an image according to a job specification and that the combination of toners includes two toners in the multi-development module, developing and transferring first toner separations onto the receiver including a first one of the two toners in the multi-development module with the controller further being arranged to cause the receiver to pass through the print engine a second time to allow a color separation to be developed using the other of the two toners in the multi-development module and transferred onto the first toner separations;
- and
- wherein the controller is further arranged to determine that the identified combination of toners does not include two toners in the two development stations in the multi-development module, forming and transferring a first combination of the identified toner separations onto the receiver and diverting the receiver to at least one of an inverter and an exit.
