## Abstract

Examples disclosed herein relate to a device including a bail arm to rotate and oscillate. Examples include a shaft coupled above an output tray; and a bail arm to rotate and oscillate about a central axis of the shaft. In examples, the bail arm is to provide a downward force on the output tray.

## Claims

### Claim 1

A device, comprising:
a shaft coupled above an output tray; and
a bail arm to rotate and oscillate about a central axis of the shaft and to provide a downward force on the output tray, wherein the bail arm includes a first angled surface oriented to engage and guide insertion of media onto the output tray from a direction perpendicular to a media output path.

### Claim 2 (depends on 1)

The device of claim 1, further comprising:
a first protrusion upon which the bail arm is to oscillate.

### Claim 3 (depends on 2)

The device of claim 2, further comprising:
a second protrusion disposed opposite the first protrusion to limit the oscillation of the bail arm about the central axis to a limited angle of rotation.

### Claim 4 (depends on 3)

The device of claim 3, wherein the limited angle of rotation is in a range up to 5 degrees.

### Claim 5 (depends on 3)

The device of claim 3, wherein the limited angle of rotation is in a range up to 3 degrees.

### Claim 6 (depends on 1)

The device of claim 1, wherein the bail arm includes a first contact portion and a second contact portion to apply the downward force on the output tray.

### Claim 7

A bail arm assembly, comprising:
a shaft to couple to a device; and
a bail arm coupled to the shaft to rotate and oscillate about a central axis of the shaft including:
a tapered U section to provide a downward force a first contact portion and a second contact portion; and
an angled surface extending from the first contact portion oriented to engage and guide insertion of media onto an output tray from a direction perpendicular to a media output path.

### Claim 8 (depends on 7)

The bail arm assembly of claim 7, wherein the bail arm further includes a first protrusion upon which the bail arm is to oscillate.

### Claim 9 (depends on 8)

The bail arm assembly of claim 8, wherein the bail arm further includes a second protrusion disposed opposite the first protrusion to limit the oscillation of the bail arm about the central axis to a limited angle of rotation.

### Claim 10 (depends on 9)

The bail arm assembly of claim 9, wherein the limited angle of rotation is in a range up to 5 degrees.

### Claim 11

A output tray assembly comprising:
a surface to receive media;
a shaft coupled to the output tray above the surface; and
a bail arm coupled to the shaft to rotate and oscillate about a central axis of shaft, wherein the bail arm includes a first angled surface oriented to engage and guide insertion of media onto the output tray from a direction perpendicular to a media output path.

### Claim 12 (depends on 11)

The output tray assembly of claim 11, wherein the bail arm includes a first contact portion and a second contact portion to apply a force to the surface.

### Claim 13 (depends on 11)

The output tray assembly of claim 11, further comprising a first protrusion and second protrusion disposed opposite the first protrusion to limit the oscillation of the bail arm about the central axis.
