Implementation of a secure network may be provided by analyzing packet traffic for sensitive information. The system identifies a first caption associated with one of the first images, identifies a second caption associated with one of the second images, selects the one of the first images or the one of the second images as a representative image for the cluster based on the first caption or the second caption, and associates the representative image with the cluster. The method includes providing wireless access to communication services to wireless communication devices, where the wireless communication devices are associated with at least a first paging zone. In one embodiment the planarizer is rotated at a constant angular velocity by a motor and the current supplied to the motor is monitored, and a print head supplied with a firing voltage is used to dispense the build material.
