A method of scheduling an event with respect to a hard copy output engine includes detecting a first status of a first portion of the hard copy output engine from a first sensor incorporated in the hard copy output engine and detecting a second status of a second portion of the hard copy output engine from a second sensor incorporated in the hard copy output engine. Data and control symbols that overlap in time-domain within a transmission time interval are multiplexed and transmitted employing resources scheduled for data transmission, whereas data and control code symbols that are not multiplexed are transmitted in respective allocated resources. The second region is of the second conductivity type and is formed in the first well.
