20100194812 | MEDIA ADVANCE SYSTEM FOR A PRINTER AND METHOD OF ADVANCING A PRINT MEDIUM - A media advance system for a printer, the system comprising: a drive roller for advancing the print medium, said drive roller being mounted on a first spindle, a second rotary element mounted on a second spindle for applying tension to the print medium downstream of said drive roller, a drive motor operatively connected to said first spindle, and a second motor operatively connected to said second spindle, wherein the velocity of the drive motor is constantly adjustable and the velocity of the second motor is constantly adjustable to the instantaneous velocity of the drive motor. | 08-05-2010 |
20100196076 | PRINT MEDIUM HANDLING - A method of assisting in handling a print medium on a spindle, said spindle being operatively connected with a motor, said method comprising the following steps: rotating said spindle by an outside force in a first direction when handling the print medium, said rotation generating an electromotive force in said motor in a second direction, opposite to said first direction; and causing the motor to apply a torque in said first direction, said torque being proportional to the electromotive force generated in the second direction by the rotation of the spindle. | 08-05-2010 |
20110017082 | Printing system - Print system, having two substrate roll supports for mounting substrate rolls, a drive assembly arranged to rotate substrate rolls, and a transmission arranged to transmit a torque from the drive assembly to the substrate roll supports so that during use the torque acting on each substrate roll is approximately equal. | 01-27-2011 |
20110311290 | MEDIA ADVANCE - Calibrating a media drive, comprising advancing media with a media drive while detecting media advances within the printer, determining an error in the media advances, and calibrating the media drive so as to at least partly compensate for the determined error. | 12-22-2011 |
20130135415 | TENSION MODULE FOR WIDE FORMAT INKJET PRINTERS - Systems and methods for wide format ink printing are described. In one embodiment, a tension module for wide format inkjet printers is described which includes a throughput roller comprising a material having a length to diameter ratio of at least 10:1 and a friction coefficient value less than 1. The tension module further includes a plurality of pinch rollers adjacent to and supporting the throughput roller, and a motor operable to rotate the throughput roller. The plurality of pinch rollers and the rotation of the throughput roller in combination are operable to draw the print medium between the plurality of pinch rollers and the throughput roller. | 05-30-2013 |
20130298790 | Printing system - Print system, having two substrate roll supports for mounting substrate rolls, a drive assembly arranged to rotate substrate rolls, and a transmission arranged to transmit a torque from the drive assembly to the substrate roll supports so that during use the torque acting on each substrate roll is approximately equal. | 11-14-2013 |
20140307016 | TENSION MODULE FOR WIDE FORMAT INKJET PRINTERS - Systems and methods for printing are described. One example is a tension module for a printer including a throughput roller including a length to diameter ratio of at least 10:1 and a material on the surface thereof having a friction coefficient value less than 1. In addition, the module includes a plurality of pinch rollers arranged parallel to the throughput roller and, the pinch rollers supporting the throughput roller and providing a pressure on a print medium when passed along the throughput roller. Further, the module includes a motor to rotate the throughput roller. Still further, the module includes a tension lever including a plurality of stops, each of the stops being associated with one of a plurality of tension settings. Manipulation of the tension lever between two of the stops adjusts the pressure between the throughput roller and the pinch rollers on the print medium. | 10-16-2014 |
