Abstract: A waste removal and transfer assembly for a 3D printing system comprises a waste material remover and a waste material collector. The waste material remover comprises a movable waste removing element selectively movable into contact with a planerizer roller to remove 3D printing waste material from the planerizer roller. The waste material remover is coupled to translate with the planerizer roller and comprises an opening leading to a waste material receptacle configured to receive waste material and at least one port selectively operable to transfer waste material from the waste receptacle. The waste material collector has a receiving position that is stationary relative to the waste material remover. The waste material collector comprises an opening and a waste material storage recess to receive waste material transferred from the waste material remover via the at least one port and to store the received waste material for subsequent disposal.

Abstract: An image formation device having computer readable instructions that alleviate the necessity of the user to enter the correct page size into the image Formation device. The computer readable instructions contain, among other things, a look-up table, or map, of known print media dimensions the image formation device is able to handle. The size of the media loaded into the image formation device is detected and assigned a value according to the look-up table, or map, of the computer readable instructions. The value is compared to the known types of media that are supportable by the printer. These types of media are grouped into predetermined categories according to their respective width dimensions. A determination of whether the image formation device performs a function is made based on the comparison of the converted value to the predetermined group of media.

Abstract: A print media delivery system on a door assembly that is connected to an associated frame is provided. The door assembly includes a door body openable to provide access into an associated frame. A tray is pivotally connected to the door body for receiving associated print media thereon. A pick roller is rotatably mounted to the door body for contacting the associated print media and advancing the associated print media into the associated frame. A gear has a missing teeth section and is connected to the pick roller for corotation therewith. A gear bias system urges the gear to rotate in a first direction when the door body is closed and said tray is open to selectively advance the missing teeth section past an associated drive gear and allow teeth of the gear to engage the associated drive gear when the door body is closed.

Abstract: Systems and methods for deskewing a substrate with at least one of a first substrate supplying member and second substrate supplying member that supplies substrates to a chamber that receives the sheet supplied from both the first substrate supplying member and the second substrate supplying member.
