Paper debris (fibers, dust fillers, etc.) contribute significantly to failures in copiers. For instance: debris in the paper path fouls sensors, solenoids, and frictional materials; fillers foul fuser oil; and more recently, fibers ruin photoreceptor belts. Various solutions to these problems have been tried in the past. For example, U. S. Patent 3,396,401 shows that it is old to use a vacuum system to remove loose toner from the surface of a copy sheet. In U. S. Patents 4,522,488 and 4,556,890, vacuum cleaning systems are disclosed that include screens or bristles that contact with the printhead or the recording surface of magnetic tape in a magnetographic printing device.
