An example of the claim method includes, in response to detecting a rejected media unit, directing a media feed path towards a reject area. The method includes depositing the rejected media unit into the reject area. The reject area is defined by a cassette surface on a body of the ribbon cassette. The ribbon cassette is unable to be removed from the media processing device until the rejected media unit is removed from the cassette surface.

A second roller set is disposed separately from a first roller set in one direction of the conveyance direction, and includes an intermittent roller that generates, during one rotation, a conveyance enabled time of contacting the card and conveying the card and a conveyance disabled time of not contacting the card and not conveying the card. A third roller set is disposed separately from the second roller set. A reference guide wall receives abutments of a first end portion of the card and arranges a position of the card in the width direction at a reference position. An urging guide wall urges a second end portion of the card toward the reference guide wall by a first urging force. A support wall regulates a movement of the reference guide wall toward the urging guide wall at a position serving as the reference position.

A drop-on-demand plastic card printer includes a tray disposed underneath the plastic card during drop-on-demand printing to catch any overspray that may occur during printing on the plastic card. The tray may be disposable so that the tray is intended to be removed and disposed of. An ink absorbent pad can be disposed in the tray to absorb the oversprayed ink. The ink absorbent pad can be disposed of along with the tray or disposed of separately from the tray.

An apparatus includes an input bin for receiving a stack of envelopes, a conveyor for conveying each envelope of the stack along an envelope path, and a cartridge retainer adapted for electrical connection to an inkjet cartridge defining a 1M array of inkjet printing nozzles. The apparatus further includes a controller electrically coupled to the cartridge retainer and configured to activate the inkjet cartridge nozzles to deposit ink droplets according to a predetermined duty cycle able to cause printing, on an envelope conveyed at a first feed rate, a first indicium having a density of MN dots per inch, where N is greater than M/2 and less than M. The conveyor, however, conveys envelopes faster than the first feed rate, whereby the first indicium is printed at a density of less than MN dots per inch on a moving envelopes.

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.

An ink jet card printer includes an ink jet print head, a gantry, and a card feeder. The ink jet print head is configured to perform a print operation on a card supported in a print position along a processing axis. The gantry is configured to move the print head through a print zone. The card feeder includes a feeder frame, a first pinch roller pair, and a lift mechanism. The first pinch roller pair is supported by the feeder frame and is configured to feed individual cards along a card feed axis. The lift mechanism is configured to move the feeder frame and the first pinch roller pair between a lowered position, in which the card feeder is displaced from the print zone, and a raised position, in which at least a portion of the card feeder extends into the print zone.

Systems and methods where a delay time between a first card processing mechanism, such as a drop-on-demand printer that prints with UV curable ink, and a second card processing mechanism, such as a UV curing station, can be altered to adjust the travel time of the card from the first card processing mechanism to the second card processing mechanism. First and second card buffers can be provided between the first card processing mechanism and the second card processing mechanism. Each of the first and second card buffers is independently logically controlled to permit independent control of the transport time of a card through each card buffer. Alternatively, a single card buffer or more than two card buffers can be provided between the first card processing mechanism and the second card processing mechanism.

An ink jet card printer includes a card transport and a print unit. The card transport includes a first belt, a first motor configured to drive the first belt to feed a card along a processing axis, a second belt, and a second motor configured to drive the second belt to feed a card along the processing axis. The print unit includes an ink jet print head and a gantry. The ink jet print head is configured to perform a print operation simultaneously on a card supported in a print position on the first belt and on a card supported in a print position on the second belt. The gantry is configured to move the ink jet print head along a fast scan axis that is parallel to the processing axis and a slow scan axis that is perpendicular to the processing axis.
