Abstract: Embodiments described herein include an upstream measurement module, a curler downstream of the upstream measurement module, and a print station downstream of the curler. The upstream measurement module includes a transport on which media is tacked to flatten the media and a curl sensor to generate a curl signal corresponding to a media curl of the media on the transport. The curler curls the media in response to the curl signal to reduce a magnitude of the media curl. The print station includes a marking unit to dispose a marking material on the media and a transport to transport the media past the marking unit, wherein the first and second transports apply a substantially equivalent hold down force to the media.

Abstract: Embodiments described herein are directed to characterizing a media curler for a printing. Test curls can be imposed on media having input curls with known input values using a media curler to be characterized. The media curler can impose the test curls based on curler settings of the media curler. Resulting output values from an interaction between the test curls and the input curls can be measured and the curler settings can be characterized based on the known input values and the resulting output values so that the media curler can be configured to respond to incoming media having a known input curl by applying curler setting to achieve a desired output curl.

Abstract: A quad-roll curler apparatus includes a first roll, a second roll, a third roll, and a fourth roll. The curler apparatus is adjustable to a first processing configuration wherein three of the four rolls are engaged to impart a curl in a sheet in a first direction. The curler apparatus is adjustable to a second sheet processing configuration wherein three of the four rolls are engaged to impart a curl in a sheet in a second direction that is different from the first direction.

Abstract: A tri-roll curler apparatus includes an inlet roll, and exit roll, and a penetrating roll. The three rolls have substantially equal radii. At least one of the penetrating roll, and the inlet and exit rolls may be movable. Distances between the penetrating roll and the inlet roll, and the penetrating roll and the exit roll are substantially equal.

Abstract: Devices and methods provide route guidance by maintaining a plurality of user preferences, receiving a beginning location and an ending location of a trip, and receiving a trip purpose of the trip. Such devices and methods automatically generate multiple different routes between the beginning location and the ending location, automatically create a subset of less than all of the user preferences that match the trip purpose to produce purpose-specific preferences, and automatically rank the multiple different routes by ranking routes that match more of the purpose-specific preferences ahead of routes that match less of the purpose-specific preferences to produce a ranked order. Then, such devices and methods automatically output the multiple different routes in the ranked order.

Abstract: Embodiments described herein include a substrate media registration system in a printing system. The registration system can include a deskewing system, a reflexive system, and a controller. The deskewing system is configured to deskew substrate media. The reflexive system is configured to detect the lateral position of the substrate media and at least one of a lead edge and a trail edge of the substrate media being transported in the process direction. The controller is operatively coupled to the reflexive system and is configured to control ejection of ink from a print head system in response to detecting the lateral position of the substrate media and at least one of the lead edge and the trail edge of the substrate media.

Abstract: An apparatus has a sheet path moving sheets of media within the apparatus and a curling/decurling station positioned along the sheet path. The curling/decurling station has a first set of rollers that impart or remove curl from a first type of sheets of media moving along the sheet path, and a second set of rollers that impart or remove curl from a second type of sheets of media moving along the sheet path. The first type of sheets have a different stiffness than the second type of sheets and are most effectively curled/decurled differently by the different sets of rollers.

Abstract: A printing system and method using alternating control modes for one or more, but not all, sheet transport devices in order to avoid contention. In a printer having first, second and third sheet transport devices in series (e.g., registration, image transfer and image fixing devices), the second device can always operate in a velocity control mode. However, the first and/or third devices can alternate between velocity and torque control modes. For example, the first device can operate in a torque control mode, when a sheet is concurrently engaged by both the first and second devices, and in a velocity control mode at other times. Additionally or alternatively, the third device can operate in a torque control mode, when a sheet is concurrently engaged by both the second and third devices, and in a velocity control mode at other times. Transition control modes can be implemented to generate smooth transitions between modes.
