PTR Cleaning

The ITB/PTR cleaning motor drives the PTR roller, PTR cleaning roller, lubricant roller, and used toner collection coil. The PTR unit (like the ITB unit) has its own cleaning unit.

• Paper dust is cleaned from the PTR by the cleaning roller (a soft brush roller), and then the cleaning blade cleans the surface of the roller.
• Paper dust and toner cleaned from the surface of the roller drop into a rotating toner collection coil for transport to the toner collection bottle.
