    Abstract: An example apparatus includes a non-transitory computer-readable medium with instructions stored thereon to perform apparatus component initialization sequences. The apparatus component initialization sequences include a full initialization sequence and a short initialization sequence, A processor is to execute the instructions to capture apparatus component state information, determine upon reception of a signal indicative of power on of the apparatus whether a position of an apparatus component is within a threshold of an expected position, perform the short initialization sequence if the position of the apparatus component is within the threshold and using the captured apparatus component state information.

    Abstract: A media registration system including an accumulation region and a transport track to receive and transport each media sheet of a series of media sheets forming a media job in a transport direction from an intake end to a registration end proximate to the accumulation region, and to stack the media sheets of the media job in the accumulation region to form a job stack. A translator adjusts a position of the registration end of the transport track in a direction lateral to the transport direction for each sheet to align edges of each sheet of the job stack in the lateral direction. A media sensor indicates a position of each sheet along the media path to facilitate a controller to determine an accumulation status of the job stack.

    Abstract: A printer mechanism includes a printhead to print on a print medium, and a platen located generally adjacent the printhead such that the platen and the printhead define a print zone therebetween. The platen includes a plurality of elongate ribs that project from an upper surface of the platen in a spaced relationship and positioned to contact a lower surface of the print medium such that the print medium bends downwardly between the ribs to provide an undulated section of the print medium with hills and valleys in the print zone. At least one shape control mechanism transforms each of the hills in the print zone into a corresponding valley in an output path adjacent to the print zone and transforms each of the valleys in the print zone into a corresponding hill in the output path.

    Abstract: A method includes advancing, by a controller device comprising a processing resource, a media from a roll into a printer via rollers before a printing process begins, wherein a leading edge of the media comprises a curl due to the roll. The method also includes guiding, by the controller device, the media through the printer to engage a substrate in a predetermined zone spaced downstream a predetermined distance from a roller pinch point. The method also includes holding, by the controller device, the media against the substrate in the predetermined zone to force the leading edge of the media to bend in a direction opposite the curl of the leading edge to counteract the curl of the leading edge.

    Abstract translation: 一种方法包括在打印过程开始之前，通过包括处理资源的控制器设备将介质从卷筒推送到打印机中，其中介质的前缘由于辊而卷曲。 所述方法还包括通过所述控制器装置通过所述打印机引导所述介质，以将衬底接合在与辊夹点相隔预定距离的下游的预定区域中。 该方法还包括通过控制器装置将介质保持在预定区域中的衬底上，以迫使介质的前缘沿与前缘的卷曲相反的方向弯曲以抵消前缘的卷曲。
