Continuous media printer with downstream drying
View Patent ↗A continuous media printer has a printer mechanism that prints on one or both surface of continuous print media. A media conveyor conveys media past the printer mechanism and includes rollers downstream of the printer mechanism. The rollers are located at a sufficient distance to provide a sufficient travel time from the printer mechanism to the rollers for material printed to be substantially dry when it reaches the rollers.
1. An inkjet type printer including:
a printer mechanism that prints at least one material on at least one surface of print media;
a media conveyor that engages the media to convey the media past the printer mechanism, said media conveyor including at least one driving roller or driven roller that is a part of a feed mechanism, the at least one driving roller or driven roller being the first component to engage the media downstream of the printer mechanism and being located at a distance from the printer mechanism such that the uppermost layer of the material printed onto the media is dry or substantially dry when it reaches the at least one driving roller or driven roller, and a loading mechanism comprising a pair of endless belts directing warm air blown through the belts over both surfaces of the print media, said loading mechanism being located between the printer mechanism and the at least one driving roller or driven roller.
2. The printer of claim 1 wherein the conveyor operates to convey the media past the printer mechanism at between about 0.5 m/s and about 2 m/s.
3. The printer of claim 2 wherein the conveyor operates to convey the media past the printer mechanism at about 1.6 m/s.
4. The printer of claim 2 wherein the conveyor operates to convey the media past the printer mechanism at about 0.8 m/s.
5. The printer of claim 1 wherein the conveyor is operated to convey the media past the printer mechanism as a speed such that the media takes between about 0.5 seconds and about 2 seconds to travel from the printer mechanism to the at least one driving roller or driven roller.
6. The printer of claim 1 wherein the conveyor is operated to convey the media past the printer mechanism at a speed such that the media takes between about 0.5 seconds and about 1.25 seconds to travel from the printer mechanism to the at least one driving roller or driven roller.
7. The printer of claim 1 wherein the conveyor is operated to convey the media past the printer mechanism at a speed such that the media takes between about 0.5 seconds and about 0.625 seconds to travel from the printer mechanism to the at least one driving roller or driven roller.
8. The printer of claim 1 wherein the conveyor is operated to convey the media past the printer mechanism at a speed such that the media takes between about 0.5 seconds and about 1 second to travel from the printer mechanism to the feed mechanism.
9. The printer of claim 1 wherein the media travels along a path about 1 m in length between the printer mechanism and the at least one driving roller or driven roller.
10. The printer of claim 9 wherein the conveyor is operated to convey media past the printer mechanism at between about 0.5 m/s and about 2 m/s.
11. The printer of claim 1 wherein the print media is continuous.
12. The printer of claim 1 wherein the at least one driving roller or driven roller engages the media on the printed material surface.
