Printhead Lens Cleaner Drive - Lexmark CX825 Service Manual

Printhead lens cleaner drive

The printhead lenses are cleaned by wiper brushes so that they are free from contamination. At the same time,
the sensor (TPS) and the sensors (auto alignment) are also cleaned.
Note: TPS stands for toner patch sensing. The sensor (TPS) detects the toner density of individual toners on
the belt. The sensor (auto alignment) checks if the different colors are aligned with each other.
The motor (printhead wiper) drives the wipers and TPS mechanism.
1 Sensors (auto alignment)
