Fixing devices for fixing marking material to a web, printing apparatuses and methods of fixing marking material to a web are provided. An exemplary embodiment of the fixing devices includes a first roll including a heated outer surface; a second roll forming a fixing nip with the outer surface of the first roll at which a continuous web on which marking material is disposed is received; a third roll positioned to contact the web prior to entering the fixing nip; and an adjustment mechanism connected to the third roll. The adjustment mechanism is operable to move the third roll to vary a wrap length of the web contacting the outer surface of the first roll upstream from the fixing nip to control pre-heating of the web and marking material by contact with the outer surface prior to entering the fixing nip. The first roll and second roll are operable to apply heat and pressure to the pre-heated web and marking material at the fixing nip to fix the marking material to the web.

A radiation curable gel ink spreading system includes a print head for jetting radiation curable gel ink onto a front side of a substrate, a heated re-flow drum for contacting a back side of the substrate to heat the gel ink and cause the ink to re-flow, and at least one radiation source that irradiates the heated ink to reduce or stop re-flow. A re-flow drum temperature, amount of radiation emission per unit time, radiation source location including a substrate wrap angle with respect to the re-flow drum and/or the radiation source, a distance between a re-flow zone start and the radiation source, and a gap distance between the radiation source and the substrate, and a process speed or substrate translation speed are adjustable for achieving desired spreading characteristics.

Apparatuses useful for printing and methods of are provided. The apparatus includes a user interface for operating the printing apparatus, a fuser for fusing media, the fuser having a plurality of temperature settings, a gloss meter for measuring gloss of an image fused on the media, and a controller controlling the printing apparatus, wherein the controller: a) causes fusing of a plurality of media of a first type at a nominal fusing temperature, and then measuring a temperature of the pressure roll as a steady state pressure roll temperature, b) causes media of the first type to be input to the fuser to fuse an image onto the media, the fuser having a first fusing temperature, c) causes the gloss meter to measure a gloss level of the image fused on the media, and sending the measured gloss level with the first type of media to the controller, d) causes steps b) and c) to be repeated at various fusing temperatures different from the first fusing temperature, and saving the measured gloss levels with corresponding fuser temperatures, e) in response to a user indication of a desired gloss level received over the user interface, sets a temperature of the pressure roll to the steady state pressure roll temperature, and f) fuses media utilizing one of the measured fusing temperatures corresponding to the desired gloss level.

A dual mode imaging device includes an input for supplying a recording medium to the printer. The recording medium can be erasable media and/or a non-erasable media. A carriage assembly within the imaging device includes guide rails, the carriage assembly reciprocal along the guide rails and parallel to an imaging surface of the recording medium. The carriage assembly includes an ink jet print head for imaging a non-erasable media in a first print mode and a write head having a UV imaging light source for imaging erasable media in a second print mode. The device further includes a heater provided on the carriage assembly for selectively heating the erasable media to one of an erase temperature and a UV imaging temperature. The heater can be proximate to or incorporated with the UV write head.

Fixing systems apply at a fixing nip low or ambient temperatures and moderate pressures or relatively high pressures to a substrate on which marking material is deposited. Fixing systems are integrated with a base print engine of a printing system, or added inline as a module to a printing system. Fixing systems and printing systems containing fixing devices and systems, including multi-stage fixing systems accommodate a broad range of substrates.

An imaging device includes an input for supplying an erasable medium to the imaging device, the erasable medium comprising at least one of an imaged and a non-imaged erasable medium. The imaging device further includes an erase subsystem comprising active and inactive states, the erase subsystem erasing an imaged erasable medium in an active state, a cooling subsystem for selectively cooling an erased medium, and a write subsystem for imaging a received medium. The device further includes a user interface for configuring the imaging device and a sensor for detecting the type of input medium.

An erasable media imaging device includes an input for supplying erasable media to the imaging device, the erasable media being one of an imaged erasable medium and a non-imaged erasable medium. An erase subsystem is provided for erasing an imaged erasable medium and a write subsystem is provided for imaging a non-imaged erasable medium, the erase subsystem and function decoupled from the write subsystem and function. In a corresponding method, one of an imaged erasable medium and a non-imaged erasable medium are supplied to the imaging device. The method further includes selecting only one of an erase mode and a write mode, the erase mode decoupled from the write mode, erasing an imaged erasable medium in the erase mode, and imaging the non-imaged erasable medium in the write mode.

Fusers, printing apparatuses and methods of fusing toner on media are disclosed. An embodiment of a fuser for fusing toner on a medium includes at least two modules arranged along a process direction of the medium, each module having an ON state in which the module discharges a hot gas and an OFF state in which the module does not discharge the hot gas; and a controller connected to the modules for controlling the ON/OFF state of each module to control the discharge of the hot gas from each module onto the medium as the medium is transported past the modules in the process direction.
