1. A printhead for a device capable of printing, comprising:
a frame; a light-emitting diode (LED) assembly including:
a housing engaged with the frame;a plurality of LEDs on the housing and extending in a first transverse direction; and,at least one lens:
parallel to the plurality of LEDs in the first traverse direction; and,arranged to focus light from the LEDs; a displacement assembly connected to the frame and engaged with the LED assembly and arranged to displace the LED assembly, with respect to the frame:
to a first position for an operating mode for the printhead, in which light from the plurality of LEDs illuminates media passing through the printhead in first or second process directions orthogonal to the first transverse direction; and,to a second position for a cleaning mode for the printhead, in which a cleaning operation for the at least one lens is enabled; and, a lens cleaning assembly engaged with the frame and including:
an arm portion extending across the frame in the first transverse direction; and,a cleaner portion including a cleaning element, wherein the lens cleaning assembly is displaceable in the first transverse direction to slide the cleaning element across the at least one lens, wherein: in the operating mode for the printhead, the lens cleaning assembly is displaceable so that the cleaning element is misaligned with the housing in the first direction; and, in the cleaning mode for the printhead, the lens cleaning assembly is displaceable in the first transverse direction to contact an entirety of the at least one lens with the cleaning element. |
