Abstract
A method and apparatus for controlling a print engine of a page printer according to a position of printing paper are disclosed. The method includes a stand-by process for initializing each portion of the print engine to a printable state when a power source is applied and checking if a printing start key is depressed, a printing ready process for applying commands for performing a driving start of a print engine motor positioned inside the print engine, setting a printing condition set of a charge unit and a developing unit, and feeding printing paper feeding through each controller when the printing start key is depressed, and checking if a first detecting signal generated by a first sensor disposed between a pickup roller and a register roller is received, a printing process for providing a command for driving the register roller when the first detecting signal is received in order to arrange the printing paper, and sequentially applying exposing, developing and transfer commands in response to a page synchronizing signal generated when the page of printing data is newly started, and a printing release process for providing the command for returning to the stand-by process in response to a second detecting signal generated by a second sensor installed downstream of a fusing unit.
