Systems and techniques for preserving and improving ink jet nozzle health and printing reliability are disclosed herein. The method may include monitoring whether a triggering event has occurred. In response to detecting the triggering event has occurred, pumping at least a portion of ink contained in a header tank in a direction toward an ink cartridge through a tube connecting the header tank to the ink cartridge. The header tank connected to a print head included as a part of a scan head. The method may further include circulating the ink through the tube back into the header tank, and agitating the scan head by moving the scan head along an x-y gantry. Additional methods may include reverse purging, ejecting a portion of ink through nozzles on the print head while simultaneously wiping a nozzle plate included on the print head, and randomizing print head location when printing.

Ink jet nozzle health and printing reliability

Systems and techniques for improving ink jet ink durability and adhesion to a substrate. The techniques may include applying a varnish to the surface of the substrate, curing, in an initial curing step, the varnish with an ultraviolet (UV) lamp, and applying a pigmented ink to at least a portion of the substrate. The initial curing step may comprise pinning the varnish with the UV lamp in a low-power state. The techniques may additionally or alternatively include applying a layer of pigmented ink and varnish at substantially the same time, allowing the pigmented ink and varnish to at least partially mix, then pinning or curing the ink/varnish combination.

Method for ink jet durability and adhesion

Techniques for operating a printer are provided. In an example, the printer can include a print head a cure light and a controller. The controller can be configured to move the print head relative to a print media to print a given image, to move the cure light relative to the print media at a cure speed in response to the cure light passing over a printed portion of the given image to cure the ink of the given image, and to move the cure light at an index speed in response to the cure light passing over a non-printed portion of the given image, wherein the index speed is greater than the cure speed.

Ink jet printer production techniques

A card encoding system comprises a belt to receive an encodable card on a first surface of the belt; a contactless encoding module including an encoding antenna, wherein the encoding antenna is positioned opposite a second surface of the belt; and a belt drive controller configured to rotate a drive roller to move the belt to position the encodable card for encoding using the encoding antenna.

E-card encoder module

An asymmetric thermal print head includes a print head body and a plurality of print elements supported on the print head body. The print elements are aligned along a first axis. Each print element includes a heater portion having a burn width measured along the first axis corresponding to a first print resolution, and a burn length measured along a second axis, which is perpendicular to the first axis, corresponding to a second print resolution. The second print resolution is higher than the first print resolution. One or more control circuits are configured to individually activate the print elements.

Thermal printhead having asymmetric recording elements

In a method of operating an ink jet card printer, which includes a transport belt, a print unit including an ink jet print head, a sensor and a gantry, a card is loaded onto the transport belt along a processing axis using an exposed surface of the transport belt. The sensor and the ink jet print head are moved relative to the card using the gantry. A current position of the card is detected using the sensor. An image is printed to the card using the ink jet print head when the detected current position of the card indicates that the card is supported on the transport belt in a print position. Printing is interrupted when the detected current position of the card indicates that the card is not in the print position.

Embodiments of the invention are directed to a transfer lamination process and apparatus that reduces substrate warpage. In some embodiments, the transfer lamination process is performed using a transfer lamination device, which includes a transfer unit, a substrate rotator, and a transfer ribbon having a carrier layer and a transfer layer attached to the carrier layer. In some embodiments of the transfer lamination process, a transfer section of the transfer layer is transferred from the carrier layer to a first surface of a substrate using the transfer unit. In some embodiments of this transferring step, the transfer section is heated and pressed against the first surface of the substrate using the transfer unit, and the carrier layer is detached from the transfer section. The substrate is then inverted using the substrate rotator. At least a portion of a second surface of the substrate that is opposite the first surface is then heated using the transfer unit without transferring the transfer layer to the portion of the second surface.

Card substrate warpage reduction

In a method of laminating a transfer layer to a substrate, a transfer layer is provided on a carrier layer. Portions of the transfer layer are selectively removed from the carrier layer using an adhesive panel by heating portions of the adhesive panel corresponding to the portions of the transfer layer, and transferring the portions of the transfer layer from the carrier layer to the adhesive panel. A transfer section of the transfer layer is then transferred from the carrier layer to a surface of the substrate by fracturing the transfer layer along an edge of the transfer section.

Transfer lamination

A card printer comprises a print platen, a first support, a printhead, and a biasing component. The first support is moveable, relative to the platen, between print and withdrawn positions. The printhead is moveably mounted to the first support for movement between a forward position and a floating position relative to the first support. The biasing component is configured to apply a biasing force to bias the printhead toward the forward position.

A card cleaner roller assembly for use in an identification card printer includes first and second cleaner pinch rollers, first and second tape rollers, first and second brackets, and a biasing mechanism. The first and second cleaner controllers are adapted to receive a transported card therebetween. The first and second tape rollers support a cleaning tape loop that is sandwiched between the second cleaner roller and the first tape roller. The cleaning tape loop includes a debris-collecting exterior surface that engages the second cleaner roller. The first bracket supports the first and second cleaner rollers and the first tape roller. The second bracket supports the second tape roller. The first and second brackets are assembled in sliding arrangement with each other and include a roller release position and an operating position. The biasing mechanism is configured to bias the first and second brackets in the operating position.

A swing arm assembly includes a swing frame, a laminating roller, and a motor. The swing frame is rotatably mountable to a frame of a card laminator for pivotal movement relative to the frame between open and closed positions. The laminating roller is movably mounted to the swing frame. The motor is mounted to the swing frame and is configured to drive a roller actuator to move the laminating roller relative to the swing frame between a laminating position and a recessed position.

An identification card manufacturing system that includes first and second identification card manufacturing device modules and a unification mounting. The first identification card manufacturing device module includes a first card transport mechanism and an output, through which the card transport mechanism is configured to discharge individual cards. The second identification card manufacturing device module includes a second card transport mechanism and an input, at which the second card transport mechanism is configured to receive cards. The unification mounting positions the output of the first device module in card handoff alignment with the input of the second device module.
