ABSTRACT:
In accordance with the invention, there is provided an improved cleaning nozzle for use in a cleaning station of a reproduction apparatus. A vacuum is applied through the cleaning nozzle to remove debris from a cleaning brush located in the cleaning station. The cleaning nozzle, which protrudes into the brush, includes a member defining a slot through which the vacuum may be applied. The member has an essentially flat leading end which protrudes into the brush and which defines a tapered entrance to the slot. In a modification of the invention, the nozzle protrudes into the brush by a distance in the range of between about 0.025 cm and 0.050 cm, preferably 0.038 cm. Additionally, the entrance to the slot is tapered from the leading end by an angle of about between 50 and 70 degrees, preferably 60 degrees.
