  • Patent number: 9987859
    Abstract: Systems and methods for evenly heating a drum dryer of a print system. In one embodiment, the dryer is configured to rotate about an axis oriented in a lateral direction, to receive a radiant energy source disposed inside the drum that extends between each lateral end of the drum in the lateral direction, and to receive a reflective assembly inside the drum that includes an inner portion and an outer portion. The inner portion surrounds the radiant energy source and removably attaches the reflective assembly to a lateral end of the drum. The outer portion extends from the inner portion in a radial direction of the drum that is perpendicular to the lateral direction. The outer portion includes a reflective surface that reflects radiant energy from the lateral end to the central portion of the drum in contact with the web.

  • Publication number: 20150145914
    Abstract: Systems and methods are provided for aligning an edge of a web of continuous-forms print media in a printer using a crowned roller. The system comprises an edge-justified printer, a crowned roller, and an adjustment mechanism. The edge-justified printer is configured to print to a continuous-forms web of print media that uses a margin as a target alignment point for an edge of the web. The crowned roller includes an apex that is a point where the diameter of the crowned roller is largest. The adjustment mechanism is configured to adjust a lateral position of the apex to align the edge of the web with the margin.

  • Publication number: 20150124016
    Abstract: Systems and methods are provided for controlling webs of print media. One embodiment is an apparatus that includes a steering frame for a continuous-forms printing system. The steering frame includes a first roller oriented to tension a web of continuous-forms print media as the web proceeds through the steering frame, and a second roller oriented to tension the web as the web proceeds through the steering frame. The steering frame also includes a first actuator configured to adjust a lateral position of the web by pivoting the first and second roller about a first axis, and a second actuator configured to adjust a direction of the web in-plane with a surface of the web by pivoting the second roller about a second axis that is coplanar with the first axis.

  • Publication number: 20150122794
    Abstract: Systems and methods are provided for applying targeted heat to a web of print media to improve the consistency of the web prior to printing. The system comprises a heater, a sensor, and a controller. The heater is able to apply targeted heat to a web of print media before the web travels through a continuous-forms printer. The sensor is able to measure a level of tension in at least one region of the web. The controller is able to direct the heater to apply a level of heat to the at least one region based on the level of tension.
