A quilting apparatus and method for guiding a sewing machine relative to at least one layer of fabric is disclosed in one presently preferred embodiment including an adjustable quilting frame and a carriage assembly configured to mountably support the sewing machine having an arbitrary throat depth. At the same time, a carrier signal generator generates a carrier signal which is to carry the address information, and supplies it to the modulator. The air conditioning system is designed for cooling and heating the passenger compartment and for a reheat operation. The high in-plane thermal conductivity graphite substrate provides enhanced heat transfer capability to effectively move of heat away from the electronic components for improved cooling of the heat generating light emitting component and surrounding devices. The present invention allows for a very close tape-head spacing. The color toner is used in an electrophotographic color image forming apparatus using a photofixing system for fixing a toner image.
