A system implementing a method for determining smear tendency of a sheet of print media to reduce smearing on future media sheets of a similar type. The method includes creating an image on the sheet of print media. The sheet of print media is reversed to allow at least one upstream roller to contact and smear the image and create smear marks on the sheet of print media. Reference marks are created over the smear marks and at unsmeared areas of the sheet of print media. To determine the smear tendency, the reference marks over the smear marks are compared to the reference marks at the unsmeared areas. The smear tendency indicates future corrections to an imaging device to reduce smearing on the future media sheets when used by the imaging device.

A system for previewing and imaging a document includes an imaging unit having an imaging surface configured to carry the document thereon. The imaging unit also includes an image sensing member configured to capture an image corresponding to the document and an image processing member communicably coupled to the image sensing member to receive the captured image. The image processing member is further configured to convert the captured image to a digital data format. The system further includes a display unit communicably coupled to the image processing member. The display unit includes a user interface configured to exhibit a placement-guiding display object over converted captured image.

An illumination system for a scanner according to one example embodiment includes an array of visible light emitting diodes including a red, a blue and a green light emitting diode and an ultraviolet light emitting device configured to emit light predominantly in the ultraviolet region of the electromagnetic spectrum. During a scan sequence of the red, blue and green light emitting diodes, at least one of the visible light emitting diodes and the ultraviolet light emitting device are positioned to simultaneously illuminate an object being scanned. In one form, during the sequence, the blue light emitting diode and the ultraviolet light emitting device are simultaneously illuminated while in another the red light emitting diode and the ultraviolet light emitting device are simultaneously illuminated.

The invention provides an ink formulation comprising a polymer associated self-dispersed colorant. The polymer has an alkyl amino end functional group that is chemically associated by electron donation/acceptation and hydrogen bonded to surface functional groups of the colorant particles. The modified self-dispersed colorant shows improved printing quality.
