An automated decision engine is utilized to screen incoming alarms using a knowledge-base of decision rules. In a moving image display period, the light-transmitting pixel portion performs an image display and a reflective pixel portion performs a black display. A bias level of the input differential signal may be adjusted to an optimal bias point of the second stage. The monitored device is accessed using a second communication protocol if the first communication protocol is not configured to retrieve information requested from the accessed device. The temperature slopes are compared to a desired threshold temperature slope, and when a match is found, the pulse width associated with the matched temperature slope is used to drive the nozzle heaters during subsequent printer operations to print characters on a print medium. As a result, risk of infiltrating dust being guided to a contacting section of the sealing lip tip can be suppressed, and leakage caused by dust becoming caught in the sealing lip can be prevented.
