20130321544 | VACUUM PULLDOWN OF A PRINT MEDIA IN A PRINTING SYSTEM - A printing system includes one or more lineheads disposed opposite a first side of a print media and at least one vacuum assembly having a vacuum manifold disposed opposite a second side of the print media. The linehead or lineheads has one or more print zones where a liquid or ink is deposited onto the first side of the print media. The vacuum manifold is aligned with a non-print zone of each linehead and outputs a vacuum force proximate to the second side of the print media such that at least a portion of the second side of the print media is deflected away from the lineheads. The printing system can also include another component, such as a dryer, disposed over the print media and laterally adjacent to the linehead. Another vacuum manifold can be disposed adjacent to the second side print media between the linehead and the component. | 12-05-2013 |

20140085390 | VACUUM PULLDOWN OF WEB IN PRINTING SYSTEMS - According to the present invention, a printing system adapted to print on a print side of a print media is disclosed. The printing system comprises one or more vacuum assemblies. Each vacuum assembly has a vacuum manifold disposed opposite a non-print side of the print media. Each vacuum manifold has an opening proximate to the non-print side of the print media and produces a vacuum that pulls the print media towards the vacuum manifold as the print media is moved through the printing system. The vacuum manifold further includes a plurality of edge seals. Each of the edge seals includes a channel for vacuum to be applied to the non-print side of the print media, the channel having at least one opening formed in a print media contact surface of the edge seal connected to at least one opening formed in a side surface of the edge seal. | 03-27-2014 |
20140176634 | CONDENSATION CONTROL SYSTEM FOR AN INK JET PRINTING SYSTEM - Condensation control systems are provided for use with inkjet printing systems that use a combination of higher resistance flow areas and lower resistance flow areas to allow a vaporized carrier fluid reducing airflow to flow between a printing module and a receiver during printing without creating observable artifacts in a print. Removal of the vaporized carrier fluid reduces condensation. | 06-26-2014 |
20140176637 | MANAGING CONDENSATION IN AN INKJET PRINTING SYSTEM WITH CO-LINEAR AIRFLOW - Methods for operating an inkjet printing system are provided. In one method, a cross-module airflow is used to limit concentrations of an evaporated inkjet carrier fluid between barrier that is between inkjet printheads of a printing module and a receiver. In the method, inkjet droplets are printed along a first print line and a second print line as the receiver is moved past the first print line and as the receiver is moved past the second print line. A co-linear airflow that flows along with ink droplets to the receiver is also supplied. Between the first print line and the second print line the receiver is moved to create an integration area in which the cross-module airflow and co-linear airflow can integrate and flow from between the printing module and the receiver without disrupting the travel of ink droplets. | 06-26-2014 |

20150021849 | COMPACT INVERTER FOR CUT SHEET MEDIA - A media inverting system is described for a cut sheet printing system. A first media transport advances a media sheet in a first direction, the media sheet having a first side that contacts the first media transport and an opposing second side. A rotatable member having a rotation axis that is substantially parallel to the first direction receives the media sheet from the first media transport and rotates to advance the media sheet around the rotatable member. A rotatable member force mechanism is switchable between a first state where the second side of the media sheet is held to the rotatable member, and a second state where the media sheet is released. A second media transport receives the media sheet from the rotatable member and advances the media sheet in an inverted orientation in a second direction that is substantially parallel to the first direction. | 01-22-2015 |
