## Abstract

A turnbar for use in a turnover module in a printing system includes one or more air-cushioned sections and one or more friction sections. Each air-cushioned section includes holes formed in a portion of a perimeter of the turnbar. Each friction section includes a friction-inducing material disposed over or affixed to another portion of the perimeter of the turnbar. Pressurized air or gas is output through the holes to produce a cushion of air or gas between a print media and the air-cushioned section. The turnbar can include one or more pistons within the turnbar, or one or more sleeves within or around the turnbar, or a combination of pistons and sleeves, to adjust airflow through the air-cushioned section.

## Claims

### Claim 1

A method for transporting a print media over a turnbar in a turnover module in a printing system, the method comprising:
outputting air through an air-cushioned section in the turnbar, where the air cushioned section includes a plurality of holes in a portion of a perimeter of the turnbar; and
adjusting airflow through the air-cushioned section.

### Claim 2 (depends on 1)

The method as in claim 1, wherein adjusting airflow through the air-cushioned section comprises adjusting airflow through the air-cushioned section based on one or more properties of the print media.

### Claim 3 (depends on 2)

The method as in claim 2, wherein the one or more properties of the print media include a width of the print media.

### Claim 4 (depends on 2)

The method as in claim 2, wherein the one or more properties of the print media include a thickness of the print media.
