摘要： A system for printing images on a substrate includes a multiplicity of print heads mounted in a carriage and positioned a distance from the substrate. A sensor detects the thickness of the substrate as the substrate moves through the system, and a control system receives the substrate thickness information detected by the sensor and transmits signals to a motor coupled to the carriage. These signals instruct the motor to adjust the position of the carriage to maintain a desired gap between the print heads and the substrate.

摘要： This invention relates to a media weight sensor of the type that includes a transducer consisting of a metal desk with a piezoelectric element fabricated by one side which form the back of a Helmholtz resonator cavity mounted in a printer so that the media going to the printer moves across the top of the Helmholtz resonator where an opening of the resonator is located. A soft, polymeric roller is used to press for media and is the transducer. The resonant frequency of the Helmholtz is affected by the media. The mass of the media adds to the mass of the resonator, thereby lowering the resonant frequency. Consequently, the heavier than media, the more the resonant frequency is lowered.

摘要： This invention relates to a media weight sensor of the type that includes a transducer consisting of a metal disk with a piezoelectric element mounted in a printer so that the media going to the printer moves across the top of the resonator where an opening of the resonator is located. A soft, polymeric roller is used to press the media against the transducer. The resonant frequency of the resonator is affected by the media. The mass of the media adds to the mass of the resonator, thereby lowering the resonant frequency. Consequently, the heavier the media, the more the resonant frequency is lowered.

摘要： An imaging apparatus provides a machine frame including a first side frame and a second side frame. A first plurality of platen mounting members is provided which are spaced apart and extend from the first side frame. A second plurality of platen mounting members is provided which are spaced apart and extend from the second side frame. A platen is positioned to extend between the first side frame and the second side frame. The platen has a first end including a first plurality of engagement members and has a second end including a second plurality of engagement members. A biasing assembly is coupled to the machine frame, wherein the biasing assembly applies a biasing force to the platen to move the first plurality of engagement members into respective engagement with the first plurality of platen mounting members and to move the second plurality of engagement members into respective engagement with the second plurality of platen mounting members.

摘要： A printer unit comprises a first positioning mechanism and a second positioning mechanism for positioning a platen with respect to a print head when a cover frame is closed. The first positioning mechanism is constituted to restrict a change in the position of the platen to a rotation around a first positioning fulcrum, such as a lock pin. The second positioning mechanism is constituted to restrict the rotation of the platen around a first positioning fulcrum by abutment on a second positioning fulcrum, such as a lock lever spindle.
