A provisioning server can be configured to include an inventory module. A cartridge locator plate seats the cartridge against stops in the channel. This avoids the difficulty of aligning on alignment marks which are below a colored resist. When a conductive object is in a vicinity of the plane conductor, the plane conductor is coupled to the conductive object, and the wireless communication device operates as a dipole antenna in which the plane conductor and the conductive object function as a first radiation element and the coil conductor functions as a second radiation element. At least one fan is placed radially inside the heat exchanger to send the first and the second part of the coolant flow to the ends of the stator.
