Example embodiments of a diaphragm are shown and described.

Diaphragm

Various embodiments and methods relating to a guide for pressing a medium towards a surface of a drum and for retracting the guide away from the surface are disclosed.

Medium pressing guide

An embodiment of an air heating apparatus includes a mass to store heat energy and a heater to provide the heat energy to the mass.

Air heating apparatus

Structures and methods are disclosed for at least partially forming an image on a media disposed on a platen, directing air from a dryer at the platen, and circulating the air from the platen back to the dryer.

Dryer

A media hold down and heating assembly of one embodiment of the invention is disclosed that includes a dielectric against which media is positioned, a conductive heating element, and an electrostatic hold down element. The conductive heating element is to conductively heat the media through the dielectric. The electrostatic hold down element is to electrostatically hold down the media against the dielectric.

Media electrostatic hold down and conductive heating assembly

Representative embodiments provide for a controller for use with a capacitive mat, the controller configured to selectively electrically energize a first node of the capacitive mat in response to an input. The controller is further configured to wait for a first predetermined period of time, and to electrically energize a second node of the capacitive mat after the first predetermined period time. A method of the present invention provides for controlling a capacitive mat, the method including receiving an input, (and electrically energizing a first node of the capacitive mat at a first predetermined potential. The method also includes waiting for a first predetermined period of time, and electrically energizing a second node of the capacitive mat after the first predetermined period of time.) This repeats the scenario stated in lines 5&#x2013;7. The abstract only mentions one of the three methods.

Voltage control for capacitive mat

A method is disclosed for controlling a capacitive mat by energizing first and second nodes of the capacitive mat with opposite polarity, forming an image on the media, and reversing the polarity of the first and second nodes.

Capacitive mat control

The present invention provides a printer having a platen, a chassis sidewall and an attachment portion connecting the platen to the chassis sidewall. The attachment portion biases the platen toward the chassis sidewall.
