ITB Cleaning Mechanism

Belt Cleaning

The ITB cleaning brush [A], the ITB lubricant brush [B], and the toner collection coil [C] are driven by the paper transfer belt motor [E] through gears [D]. The ITB cleaning brush [A] removes paper dust on the ITB [F] and then the ITB cleaning blade [G] removes toner. The removed paper dust and waste toner are transported to the waste toner bottle by the toner collection coil [C]. The paper dust collection scraper [H] plucks paper dust and waste toner from the ITB cleaning brush, which sends it to the toner collection coil [C].

ITB Lubrication

The ITB cleaning blade [A] and the ITB lubricant blade [B] are installed against the belt movement (counter blade method). To enhance the efficiency of cleaning, lubrication is applied to the ITB by the ITB lubricant brush [C] and the ITB lubricant blade [B] spreads it evenly on the ITB.

ITB Cleaning Unit Set Sensor

When the ITB cleaning unit is inserted and the lock lever is turned, the ITB cleaning unit set sensor [A] detects the tip of the lever and the machine judges that the ITB cleaning unit is set.
