Appl. No.:

12/417836

Inventors:

Keith Jariabka - Portland OR, US
Scott Martin - Vancouver WA, US
Kieran B. Kelly - Vancouver WA, US

International Classification:

B41J 2/165

US Classification:

347 32

Abstract:

A carriage-actuated venting system for a print head of an inkjet printer includes a print head cap, selectively closable over the print head of the ink jet printer. A vent port is in fluid communication with the print head cap and vents the print head when the print head cap is closed over the print head. A movable shaft is engageable by a movable carriage of the ink jet printer. A vent actuator is coupled to and movable with the shaft to close the vent port and restricts venting of the print head through the print head cap.

International Classification:

B41J 29/02

US Classification:

400691

Abstract:

In one embodiment, a device for a printer includes a movable tray for supporting a print media. The tray is movable between an open position in which media may be moved on to the tray and a closed position in which media is blocked from moving on to the tray. The device also includes a rotatable media drive component for moving print media on to the tray and a movable restraint operatively connected to the tray. The restraint is movable between: a first position, corresponding to the open position of the tray, in which the restraint does not restrain the media drive component; and a second position, corresponding to the closed position of the tray, in which the restraint restrains rotation of the media drive component.

US Classification:

347 16, 347104

Abstract:

In one embodiment, a device for moving print media in a printer includes: a rotatable shaft extending lengthwise along an axis of rotation and a hub. The hub is operatively and pivotally connected to the shaft at a connection such that the hub rotates with the shaft about the axis of rotation and so that the hub may tilt on the shaft relative to the axis of rotation. The device also includes a pick tire or other feature on the hub on each side of the connection to move print media when the shaft rotates the hub. In another embodiment, a method for moving print media in a printer includes: applying a force to a sheet of print media at two locations spaced apart across the sheet; and, simultaneously with the act of applying, equalizing the force applied at the two locations.

International Classification:

B41J 2/175

Abstract:

An example ink tank includes a cap with a preloaded hinge that biases the cap to a fully opened position when the cap is unlatched. The cap in the fully opened position interferes with and prevents the closure of a door that provides access to the ink tank. The door includes a sensor that locks out the print function when the door is open, effecting a printer lockout when the cap of the ink tank is opened for filling.
