Abstract
A system includes a controller to adjust the speed and feed direction in which media is guided through a printer. A park control module commands the controller to guide a leading edge of the media to engage a park zone in the printer. The park zone includes a surface of a platen in the printer that is spaced a predetermined distance from a roller pinch point in the printer where the leading edge of the media is to engage the platen to mitigate roll curl in the media.
Claims19
A system comprising:
- a controller to adjust the speed and feed direction in which media is guided through a printer;
- and
- a park control module to command the controller to guide a leading edge of the media to engage a park zone in the printer, wherein the park zone comprises a surface of a platen in the printer that is spaced a predetermined distance from a roller pinch point in the printer, wherein the surface of the platen is fixed with respect to the roller pinch point and the media, where the leading edge of the media is to engage the platen to mitigate roll curl in the media.
A printer, comprising:
- a feed roller set to receive physical media from a roll of the media, the feed roller located before a print zone;
- an output roller set located downstream from the feed roller set to eject the media from the print zone;
- a controller to control the feed roller set and the output roller set to adjust the speed and direction of the media;
- and
- a park control module to command the controller to guide a leading edge of the media to a park zone in the printer such that the leading edge of the media engages a surface of a platen in the printer to mitigate roll curl in the media, wherein the park zone being located on the platen within a predetermined distance from a roller pinch point of the feed roller between the feed roller set and the output roller set.
2 more elements
A method comprising:
- advancing media via rollers before a printing process begins;
- guiding the media to a predetermined zone that is spaced downstream a predetermined distance from a pinch point in the rollers to impose a reverse-bow in the media relative to a roll curl of the media;
- and
- holding the media against a substrate in the predetermined zone for a predetermined period of time to mitigate the roll curl of the media.
