Abstract
In a printer or copier, a removable module, such as a marking material supply module or a marking device module, is provided with a non-volatile memory chip which retains information about the cumulative use of the module and other performance-related data. The non-volatile memory is accessed through a wireless interface, such as an RF loop or IR detector, which is also associated with the module. The memory can be accessed, through wireless means, either by the printer or copier itself or by an external device. The wireless interface can also be used to access a memory which is attached to part which moves within the printer or copier, such as a roller or drum, thus avoiding the use of wire harnesses.
