A printer and method for printing a secure document are disclosed. For example, the printer includes a controller for receiving an indication that a print job contains the secure document, a lock on a printer door, wherein the lock is electrically coupled to the controller, wherein the lock is engaged by the controller after receiving the indication that the print job contains the secure document and the lock is disengaged when the print job is completed successfully and a user interface in communication with the controller for receiving a security code to disengage the lock when print job is interrupted due to an error.

Secure document printer

An electrophotographic printing machine of the type in which an electrostatic latent image recorded on a charge retentive surface is developed with toner particles to form a visible image thereof. A Hybrid Scavengeless Development (HSD) developer housing designed to control toner emission by employing two internal capture&lsqb;JMC16&rsqb;, external exhaust manifolds. The location of the two manifolds are placed above and below the upper and lower donor rolls respectively. The manifolds are mounted in position to improve emissions control as well as reductions in the flow needed to accomplish the task. The upper and lower manifolds are able to control the loose toner emitted by the housing and lower powder cloud, they cannot collect the toner released by the upper powder cloud. To prevent toner accumulation in the middle regions of the wire module, a manifold is incorporated as an integral part of the wire module frame. Finally, toner released in the region between the two donor rolls near the magnetic roll surface may be controlled by inserting a baffle.
