## Abstract

A discharge system for printed media sheets and a printer which utilizes such a discharge system, the discharge system including a tray for the media sheets; rotating transport elements forming a discharge nip for discharging the sheets onto the tray; a guide plate having a surface for guiding the sheets to the discharge nip; and a rotating wheel containing bristles for guiding the sheets towards the discharge nip; the wheel facing said surface of the guide plate. At least one driven transport belt forms one of the transport elements defining the discharge nip, and the guide plate passes in approximately a one-half turn around two pulleys around which the transport belt is passed.

## Claims

### Claim 1

A discharge system for printed media sheets, comprising:
a tray for receiving the media sheets;
rotating transport elements provided at said tray forming a discharge nip for discharging the sheets onto the tray; a guide plate having a surface for guiding the sheets to the discharge nip; and a rotating wheel containing bristles for guiding the sheets towards the discharge nip wherein at least one driven transport belt forms one of the transport elements defining the discharge nip; the guide plate passing in approximately one-half turn around two pulleys around which the transport belt passes; the wheel facing said surface of the guide plate; the transport belt being arranged to guide the sheets towards the discharge nip and the wheel being arranged to guide the sheets to the transport belt.

### Claim 2 (depends on 1)

The discharge system of claim 1, wherein the wheel is laterally offset from one of the transport elements defining the discharge nip and partially intersects a cross-section of said transport element.

### Claim 3 (depends on 1)

The discharge system of claim 1, wherein the guide plate is curved and passes in approximately one-half turn around the wheel.

### Claim 4 (depends on 1)

The discharge system of claim 1, wherein the bristles are arranged in bunches distributed over the circumference of the wheel, the bunches being staggered in at least two rows.

### Claim 5 (depends on 1)

The discharge system of claim 1, wherein the bristles are made of nylon.

### Claim 6 (depends on 1)

The discharge system of claim 1, wherein the wheel is arranged coaxial to one of the pulleys; and the bristles extend further than the diameter of the pulley.

### Claim 7 (depends on 1)

A printer containing a sheet discharge system according to claim 1.
