Residual transfer toner on the OPC drums is recovered by a cleaning blade. The cleaning blade is installed in the counterclockwise direction to the drum rotation in contact with the drum and scrapes toner off.
The lubricant roller rotates in the opposite direction to the OPC drum and coats it with a solid lubricant to enhance cleaning. Also, by rotating the lubricant blade in the trailing direction instead of the conventional counterclockwise direction and replacing the lubricant coating brush with the lubricant roller, the lifetime of the device is extended.
In addition to cleaning, the solid lubricant bar suppresses wear of the OPC drum due to the blade.
