Abstract
A media size sensing system includes independently moveable length and width edge guides, in a media tray, for positioning against orthogonal edges of media sheets. A linearly sliding sensor device is provided, and a single linkage connects the length and width edge guides to the sensor device, the single linkage providing a unique position indication that is a function of both length and width for a range of media sheet sizes.
Claims15
A media size sensing system, comprising:
- independently moveable length and width edge guides, in a media tray, for positioning against orthogonal edges of media sheets;
- a linearly sliding sensor device;
- and
- a single linkage, connecting the length and width edge guides to the sensor device, the single linkage providing a unique position indication that is a function of both length and width for a range of media sheet sizes.

A printing system, comprising:
- a media tray for holding sheets of print media;
- independently moveable length and width edge guides, in the media tray, for positioning against orthogonal edges of media sheets in the tray;
- a single linkage, connected to the length and width edge guides;
- and
- a sensor device, configured to provide a media size signal depending upon a position of a distal end of the single linkage for a range of media sheet sizes.
2 more elements
A method for detecting a size of print media in a media tray, comprising the steps of:
- sliding a first edge guide against a first edge of print media in the media tray, the first edge guide being attached to a sliding pivot of a linkage;
- and
- sliding a second edge guide against a second orthogonal edge of the print media, the second edge guide being attached to a proximal end of the linkage, thereby pivoting the linkage and linearly moving a distal end thereof adjacent to a media size sensor.
