Abstract: An example assembly includes a first guide positioned in a pre-print zone area of an imaging device. A second guide rotatably is connected to the imaging device and spaced apart from the first guide to permit a print medium to traverse between the first guide and the second guide. A bearing mechanism connects the second guide to the imaging device in the pre-print zone area. An interface mechanism is operatively connected to the second guide. A bias element is positioned between the interface mechanism and the second guide to release energy upon exposing the interface mechanism to the pre-print zone area allowing rotation of the second guide away from the first guide.

Abstract: Examples of a printhead assembly are disclosed herein. An example of the printhead assembly includes a die to print, a base member, and at least one electrode. The electrode may be used to provide a charge to attract and collect particles that would normally otherwise interfere with operation of the die.

Abstract: A wiping assembly includes a pair of guide elements located at opposite ends of a headland region of a fluid ejection assembly to extend in a second orientation generally perpendicular to a first orientation through which the opposite ends extend. Each guide element includes at least one first portion and a second portion. The at least one first portion selectively receives biased releasable engagement from a non-wiping portion of a wiping element extending along the first orientation to cause a wiping portion of the wiping element to be in generally parallel relation to, and spaced apart from, the headland region. The second portion causes the non-wiping portion to no longer be in biased releasable engagement against the guide element and causes the wiping portion to be biased in wiping relation against the headland region.

Abstract: In an inkjet printer having a small print head assembly and a large print head assembly, a wiper includes a first wiper section having a width approximately equal to a width of an orifice area of the small print head assembly, a decoupler adjacent to the first wiper section, a second wiper section adjacent to the decoupler, where the first and the second wiper sections and the decoupler combined have a width approximately equal to a width of an orifice area of the large print head assembly, and a squared tip at an extremity of the single, segmented wiper to impede wicking action. A tab holds the wiper oriented so as to wipe the print head assemblies in a direction of a printing operation.
