Abstract

In one example, an output tension zone can include a first tension roller assembly to receive partially dried inkjet media at an output of a heated pressure roller, wherein the first tension roller assembly includes a first continuous roller to receive a first side of the partially dried inkjet media and a second continuous roller to receive a second side of the partially dried inkjet media and a second tension roller assembly to receive the partially dried inkjet media from the first tension roller assembly, wherein the second tension roller assembly includes a third continuous roller to receive the first side of the partially dried inkjet media and a fourth continuous roller to receive the second side of the partially dried inkjet media.

First claim

What is claimed:

1. An output tension zone, comprising:
a first tension roller assembly to receive partially dried inkjet media at an output of a heated pressure roller, wherein the first tension roller assembly includes a first continuous roller to receive a first side of the partially dried inkjet media and a second continuous roller to receive a second side of the partially dried inkjet media;
a second tension roller assembly to receive the partially dried inkjet media from the first tension roller assembly, wherein the second tension roller assembly includes a third continuous roller to receive the first side of the partially dried inkjet media and a fourth continuous roller to receive the second side of the partially dried inkjet media; and
a media guide positioned between the first tension roller assembly and the second tension roller assembly to direct air from an air circulation unit that includes a fan to increase drying of the partially dried inkjet media when the first tension roller assembly and the second tension roller assembly apply pressure to the partially dried inkjet media.

2. The output tension zone of claim 1 , wherein the media guide provides pressure to an edge of the partially dried inkjet media between the first tension roller assembly and the second tension roller assembly.

3. The output tension zone of claim 1 , wherein the first continuous roller and the second continuous roller include a continuous roller size across a width of the partially dried inkjet media.

4. The output tension zone of claim 1 , wherein the third continuous roller and the fourth continuous roller include a polytetrafluoroethylene (PTFE) coated continuous roller size across a width of the partially dried inkjet media.

5. A system for an output tension zone, comprising:
a heated pressure roller to receive partially dried inkjet media from a print zone; and
a tension zone to receive the partially dried inkjet media, the tension zone comprising:
a first assembly of continuous rollers to apply pressure along a first side and second side of the partially dried inkjet media;
a media guide to receive a first edge and a second edge of the partially dried inkjet media from the first assembly of continuous rollers to direct air from a fan to increase drying of the partially dried inkjet media when the first assembly of continuous rollers and a second assembly of continuous rollers apply pressure to the partially dried inkjet media; and
the second assembly of continuous rollers to apply pressure along the first side and second side of the partially dried inkjet media.

6. The system of claim 5 , wherein air is moved on to the partially dried inkjet media within the media guide.

7. The system of claim 5 , wherein the heated pressure roller moves at a first speed, the first assembly of continuous rollers move at a second speed, and the second assembly of continuous rollers move at a third speed to apply tension on the partially dried inkjet media.

8. The system of claim 5 , wherein first assembly of continuous rollers applies a first tension or pressure to the partially dried inkjet media and the second assembly of continuous rollers applies a second tension or pressure to the partially dried inkjet media.

9. The system of claim 5 , wherein the first assembly of continuous rollers include a first continuous roller comprising a solid core with a continuous coating to soften the first continuous roller and a second continuous roller comprising a continuous metallic roller.

10. The system of claim 9 , wherein the first continuous roller contacts a printed side of the partially dried inkjet media and the second continuous roller contacts a non-printed side of the partially dried inkjet media.

11. An output tension zone, comprising:
a first assembly of continuous rollers to apply pressure along a first side and second side of partially dried inkjet media, wherein the first assembly of continuous rollers includes a first continuous roller with a first continuous material to apply pressure across the first side of the partially dried inkjet media and a second continuous roller with a second continuous material to apply pressure across the second side of the partially dried inkjet media;
a media guide to receive a first edge and a second edge of the partially dried inkjet media from the first assembly of continuous rollers;
an air circulation unit to provide air to the first side and the second side of the partially dried inkjet media within the media guide, wherein the air circulation unit includes a fan to increase drying of the partially dried inkjet media when the first assembly of continuous rollers and second assembly of continuous rollers apply pressure to the first side and second side of the partially dried inkjet media; and
a second assembly of continuous rollers to receive the partially dried inkjet media from the media guide to apply pressure along the first side and second side of the partially dried inkjet media.

12. The output tension zone of claim 11 , wherein the first continuous material has a first level of hardness and the second continuous material has a second level of hardness.

13. The output tension zone of claim 12 , wherein the first continuous material of the first continuous roller applies pressure to a printed side of the partially dried inkjet media when the first level of hardness is softer than the second level of hardness.
