Aspects of the invention relate to hard imaging device charging systems, liquid electrophotography charging systems, hard imaging apparatuses, and hard imaging device electrophotography charging methods. In one embodiment, a hard imaging device charging system is described. The charging system may include a first charging device configured to charge a respective first region of a cylindrical image bearing member used to form latent images during hard imaging operations of the hard imaging device. The charging system may also include a second charging device configured to charge a respective second region of the cylindrical image bearing member used to form latent images during hard imaging operations of the hard imaging device. The first and second regions may have different radii from a central axis of the cylindrical image bearing member.

An ink composition has controlled conductivity, and a digital printing system and a method of printing an ink employ an offset inkjet printing platform. The ink composition includes pigment particles dispersed in an oil-based dielectric carrier fluid with an oil-soluble dispersant. A concentration of dispersant is a fraction of a concentration of the pigment particles sufficient to render an electrical conductivity of the ink composition less than 100 pico Siemens per centimeter (pS/cm). The printing system includes an ink having an electrical conductivity less than or equal to about 300 pS/cm, an inkjet print head, a transfer medium, a developer, a remover and an image transferer. In the method of printing, the ink is nonelectrostatically jetted to the transfer medium, and developed into a fixed image. A portion of a supernatant is removed from the fixed image, and the fixed image is transferred to a media substrate.

Apparatus to capture aerosols, fluid jetting apparatus, and aerosol diverters are disclosed. An example aerosol capture apparatus includes a corona wire to generate ions, and a reference plate positioned below the corona wire and above a substrate on which a fluid is to be deposited, the reference plate to provide a reference potential to direct the ions toward the reference plate to force aerosol particles associated with the fluid toward the reference plate.

An imaging device and calibration method therefore forms a plurality of hard images upon media using user-defined image data. An optical characteristic of at least a portion of the hard images is sensed at a plurality of different spatial locations of the hard images. The sensed optical characteristic is compared with the user-defined image data, and the imaging device is calibrated using the sensed optical characteristic.

Hard imaging devices, print devices, and hard imaging methods are described. According to one arrangement, a hard imaging device includes a media transport system configured to move media along a media path and a print device adjacent to the media path. The print device may include an image forming device configured to eject a plurality of droplets of a liquid marking agent in a direction towards the media moving along the media path to form hard images using the media, wherein the ejection of the droplets of the liquid marking agent from the image forming device creates puddles of the liquid marking agent on the image forming device and a puddle removal system configured to remove the puddles of the liquid marking agent from the image forming device.

Apparatus, articles of manufacture, and image forming apparatus for capturing aerosols are disclosed. An example apparatus includes a corona wire, and an excitation source to provide to the corona wire a composite signal having a direct current component and an alternating current component, the alternating current component having a cycle, a first portion of the cycle being sufficient to cause the composite signal to exceed an inception voltage at which ions are generated by the corona wire and a second portion to cause the composite signal to fall beneath the inception voltage, the excitation source to avoid causing the corona wire to substantially charge a substrate.
