MEDIA SUPPORT

HP SCITEX LTD., Netanya ...

1. A media support, comprising a sheet of elongated suction cups and circular suction cups, wherein each elongated suction cup has a length in a first direction, a width in a second direction orthogonal to the first direction, and a depth in a third direction orthogonal to the first and second directions, the length being greater than the width, and wherein each suction cup:is recessed into the sheet in the third direction along a surface of the sheet such that at least some of the suction cup is below the surface of the sheet in the third direction; and
has a port through which air may be evacuated from the suction cup with the port of each suction cup separate from the port of any other suction cup.

PRINT MEDIA EDGE REPAIR

HP SCITEX LTD., Netanya ...

1. A system comprising:a first repair element disposed relative to a media handling path to repair a first edge of a sheet of print media as the sheet of print media moves along a first direction into a position relative to a printing system;
a second repair element disposed opposite the first repair element across the media handling path to repair a second edge of the sheet of print media as the sheet of print media moves along the first direction into the position relative to the printing system, wherein the first direction is parallel to each of the first edge and the second edge;
a guide element to guide, along a second direction, the sheet of print media after the repairs by the first repair element and the second repair element, toward a print engine to apply a printing material to a surface of the sheet of print media, wherein the second direction is different from and angled with respect to the first direction; and
a damage sensor to detect damage to the first edge or the second edge, wherein the system is to:
selectively use the first repair element to repair the first edge in response to the damage sensor detecting the damage to the first edge, and
selectively use the second repair element to repair the second edge in response to the damage sensor detecting the damage to the second edge.

PRINTER INK DRYER UNITS

HP SCITEX LTD., Netanya ...

1. A method comprisingirradiating a substrate bearing a solvent-based printing substance comprising a colorant with radiation to cause evaporation of solvent fluid therefrom, comprising irradiating the printing substance with a non-laser Light Emitting Diode (LED),
wherein a waveband of the radiation is such that heating of the solvent fluid is substantially due to heat transfer from the colorant.
