A printing device is disclosed. For example, the printing device includes a processor and a non-transitory computer readable medium storing instructions, which when executed by the processor, cause the processor to receive selections for settings of a print job, save the selections as a print queue, and generate a machine readable code that contains the selections for the print queue.

Transfer of print queues via machine readable codes

A processor of a printing apparatus obtains and maintains the media type of print media located in a media storage component of the printing apparatus. The processor also accesses a reference file containing different printing speed limits for different media types. The reference file can be maintained in an electronic storage component of the printing apparatus. The processor uses the reference file to determine an appropriate printing speed limit for a printing engine of the printing apparatus that corresponds to the media type of the print media in the media storage component. Further, a user interface of the printing apparatus can display an overspeed indicator, and/or the processor can stop the printing from occurring, based on a job-set printing speed of the printing engine being above the printing speed limit.

Automated print engine speed control

A system and method are provided which enable overriding a custom color callout in a print job. Provision is made for a user to associate a unique ID with a custom color callout in a print job, e.g., during generation of the print job or at the printer. The custom color callout provides for a part of the print job to be rendered with a specific custom colorant, e.g., by identifying the name of the custom colorant. The unique ID is associated, in memory, with a custom colorant station of a print engine, independent of any custom colorant that may be housed in the custom colorant station. The method further includes identifying the custom colorant station of the print engine associated with the unique ID and sending the print job in a format for printing to the print engine for printing the part of the print job with a first custom colorant housed in the identified custom colorant station.

Accordingly, an improved system and method is provided with which an automatic analysis of the fuser oil is performed to prevent accidental oil and toner mismatches by the insertion of a photovoltaic sensor and associated logic inline along the tube that delivers the fuser oil to the fuser.

Beam strength and curl characteristics of sheets of print media change based not only on paper weight, but also on environmental conditions, such as humidity. Printers herein include a printing engine positioned to receive sheets of print media from a storage container. Sheet transport elements are positioned to transport the sheets from the storage through the printing engine. A sensor contacts one of the sheets, and the sensor detects a beam strength and curl characteristics signature profile of the sheet tested. Then, a processor (that is electrically connected to the sensor and the sheet transport elements) adjusts how the sheet transport elements contact the sheets (adjusts the angle, speed of, and force applied by, the sheet transport elements) based on the beam strength and curl characteristics signature profile.

Devices and methods for an image shift template. Information defining a document and a first print job is received into a printer. The first print job comprises instructions for printing the document and document finishing instructions. The finishing instructions are analyzed and areas of the pages of the document that will be unusable after a finishing operation according to the instructions are identified. Selection is received to print an image shift template on the document. The image shift template comprises x- and y-axes associated with the document and indication of the areas of the pages of the document that will be unusable after the finishing operation. A second print job is created comprising instructions for printing the pages of the document with the image shift template superimposed on the pages. The pages of the document including the image shift template are printed, according to the second print job.

A sheet supply device has a bottom contacting or resting on an external surface. The sheet supply device stores sheets of media and supplies the sheets of media to a processing device. The sheet supply device comprises a controller device, a platform supporting the sheets of media, and a foot-activated user input device positioned at the bottom of the sheet supply device adjacent the external surface. The platform moves upward (in a first direction away from the external surface) to supply the sheets of media to the processing device, and the platform moves downward (in a second direction toward the external surface) to allow the sheets of media to be loaded onto the platform. Operation of the foot-activated user input device causes the compartment to open and/or the platform to move downward (in the second direction).

Foot-activated media supply devices

Methods and devices automatically determine a base color gamut of base marking materials and extension color gamuts of extension marking materials. As each print job is received, these methods and devices automatically evaluate the print job to determine the print job color gamut. Then, the methods and devices can automatically determine the closest match between: the print job color gamut; and the base color gamut or one of the extension color gamuts to identify a matching color gamut. Further, these methods and devices automatically output the matching color gamut (and potentially a corresponding interchangeable supply container, if the matching color gamut is one of the extension color gamuts) by, for example, displaying the matching color gamut and the corresponding interchangeable supply container in at least one additional column in a print queue, or displaying the matching color gamut and the corresponding interchangeable supply container in a separate gamut queue.

Extension color gamut queue

Disclosed are methods, apparatus and systems of characterizing a color rendering performance of a printing system. According to one exemplary method, a user operated UI provides instructions to a printing system to automatically execute a color validation swatch process during the execution of a print job. The user provided instructions provide the parameters necessary to configure the execution of the color validation process.

Methods and systems for maintaining image quality are disclosed. A printing system and method is provided for maintaining image quality, comprising: initially establishing a plurality of image quality threshold standards; assigning an image quality threshold standard from the plurality of image quality threshold standards to an associated image job; comparing the assigned image quality threshold standard of each associated image job to a system check value; and, marking any image jobs having an assigned image quality threshold standard greater than the quality system check value.
