Inkjet image forming apparatus

摘要

An inkjet image forming apparatus is provided. The image forming apparatus includes an inkjet printhead that prints an image by ejecting ink on paper and has an ink refill hole through which the inkjet printhead is refillable with ink. A cover is disposed over the ink refill hole. A door covers part of a housing when closed and exposes the covered part of the housing when opened so that the inkjet printhead is accessible. A sensor detects whether the door is open or closed and outputs a door open signal or a door closed signal based on the detection results. An electrical actuator is coupled to the cover and lifts up or down the cover in response to the door open signal or the door closed signal.
