Media processing device and associated system
A printhead assembly structured to be removably received into a printhead guide of a media processing device having a platen and a biasing assembly, the printhead assembly comprising a printhead and a support body. The support body is adapted to support the printhead. The support body is structured to slidably translate within the printhead guide between a disengaged position, where the printhead is removed from the platen, and an engaged position, wherein the printhead is positioned proximate the platen. The support body defines an interface member structured to removably engage the biasing assembly.
1. A printhead assembly structured to be removably received into a printhead guide of a media processing device having a platen and a biasing assembly, the printhead assembly comprising:
a printhead; and
a support body adapted to support the printhead, wherein the support body is structured to slidably translate within the printhead guide between a disengaged position, where the printhead is removed from the platen, and an engaged position, wherein the printhead is positioned proximate the platen, and wherein the support body defines an interface member structured to removably engage the biasing assembly, wherein the biasing assembly is structured to bias the support body in the disengaged position, wherein the media processing device further comprises a lid movable between an open position and a closed position, and wherein the support body defines a drive surface that is engaged by the lid to drive the support body against the bias of the biased carrier to the engaged position as the lid transitions between the open position and the closed position.
2. The printhead assembly of claim 1 , wherein the printhead is disposed in thermal communication with a heat sink, and wherein the support body defines a duct structured to pass an air flow over the heat sink.
3. The printhead assembly of claim 2 , wherein the duct comprises at least one flow directing surface that is structured to direct the air flow over the heat sink while at least partly isolating the air flow from the printhead.
4. The printhead assembly of claim 1 , wherein the printhead assembly further comprises a latch that is configurable between a latched position, wherein the printhead is maintained in the engaged position, and an unlatched position, wherein the printhead is free to move to the disengaged position.
5. The printhead assembly of claim 4 , wherein the latch is biased toward the latched position.
6. The printhead assembly of claim 1 , wherein the support body comprises a printhead carrier and a printhead bracket.
7. The printhead assembly of claim 6 , wherein the printhead bracket supports the printhead and is structured to be removably coupled to the printhead carrier.
8. The printhead assembly of claim 7 , wherein the printhead is disposed in thermal communication with a heat sink, and wherein the printhead bracket defines a duct structured to pass an air flow over the heat sink.
9. The printhead assembly of claim 8 , wherein the duct comprises at least one flow directing surface that is structured to direct the air flow over the heat sink while at least partly isolating the air flow from the printhead.
10. The printhead assembly of claim 1 further comprising a printhead interface disposed in electrical communication with the printhead, wherein the printhead interface is positioned to engage a controller interface of the media processing device when the support body is disposed in the engaged position.
11. The printhead assembly of claim 10 , wherein the printhead interface is positioned to disengage from the controller interface of the media processing device when the support body is disposed in the disengaged position.
12. The printhead assembly of claim 4 , wherein the latch is moved from the latch position to the unlatched position via movement of the lid.
13. The printhead assembly of claim 1 , wherein the printhead is removeable from the media processing device without disconnecting the biasing assembly.
14. The printhead assembly of claim 1 , wherein the lid comprises a nose feature configured to engage the drive surface when the lid is closed.
15. The printhead assembly of claim 1 , wherein the printhead assembly is removeable from the printhead guide by sliding the printhead assembly within the printhead guide in a direction away from a base of the media processing device.
16. The printhead assembly of claim 1 , wherein the lid comprises a lid release button wherein the lid is configured to open when the lid release button is pressed; and
when the lid is opened, the support body moves to a disengaged position.
