Abstract

In a document copier, it is undesirable to leave ink carrier on a magnetic brush 1 in contact with the photoconductor 2 when the machine is turned off. The magnetic brush is cleaned, just before the machine is turned off, by deflector 3. During normal operation the deflector is positioned, as shown in full lines, to allow ink carrier 4 to flow freely onto the rotating magnetic brush. Just before the machine shuts down, deflector 3 is moved to the closed position by solenoid 5 long enough to cut off supply of ink carrier and for the magnetic brush to be cleaned. At this time the flow of ink carrier is diverted back to the sump by deflector 3. After shut down the deflector is returned to the open position by spring 6 to fill reservoir against the stationary magnetic brush.
