Abstract
An apparatus and method for cleaning a printing apparatus based on printing apparatus status information that is stored to memory in response to an externally generated reset signal. Based on the stored information, a cleaning process appropriate to the printer status is selected and performed, thereby minimizing ink consumption. In particular, when a CPU of the printing apparatus detects an external reset signal, which is based on the reset signal received from a host computer , the CPU writes the cleaning time, reset time, and other printing apparatus status information to a non-volatile RAM. The CPU is then forcibly reset by an internal reset signal. After being reset, the CPU reads the status information from the non-volatile RAM, and selects and implements a cleaning process appropriate to the stored status information. Ink consumption by the printing apparatus can thus be minimized, and reliable cleaning and printing can be maintained.
