The invention relates to a process for producing a high-quality ink-jet recorded image. Once the implement is loaded, a pivoted tongue of the implement is positioned so as to be used for the endwise transport of loaded implement. The main control unit is configured to control the power-saving remote control apparatus to enter a sleeping-power-saving mode when the controlled apparatus stops working, and then for every first predetermined time, the main control unit is turned on to wake up the remote control receiving unit to scan a plurality of wireless signals. This shiplap feature allows the headlap to exposure ratio of the shingle to be reduced to less than 1 and even to 0.
