Abstract:

The invention provides a system and method for detecting the presence of an ink jet printhead when a printhead controller fails to properly identify an installed printhead using a printhead identification device. The system includes a printhead including heater resistors and control elements, and a controller connected to the printhead via address and data lines. When the controller fails to properly identify an installed printhead, the controller operates to bias the control elements in a predetermined manner via at least one address line, detect a signal via the data lines, and generate a signal indicative of the presence of the installed printhead.
