Key specifications
Type: Optical photointerrupter
Function: Paper feed detection
Compatibility: Specific Ricoh printing equipment
Technology: Infrared light-based sensing
How to use
Installation should be performed by a qualified technician or an individual familiar with the internal assembly of the specific printer model. Before beginning, ensure the printer is powered off and disconnected from the electrical supply. Access the paper feed path according to the manufacturer's service manual, locate the existing sensor, and carefully disconnect the wiring harness. Remove the old unit and secure the new Ricoh AW020166 in the same position, ensuring the optical gap is clear of obstructions. Reconnect the wiring and perform a test print to verify that the sensor is correctly detecting paper movement.
What to consider before purchase
Verify the compatibility of the sensor with your specific printer model
Ensure the issue is related to the paper feed sensor rather than other mechanical components
Consult the printer service manual for installation requirements
Usage recommendations
To ensure optimal performance and longevity, keep the paper path clean and free of paper dust or debris that could obstruct the sensor's optical path. Regular maintenance of the printer's feed rollers will also complement the function of this sensor, ensuring consistent paper movement.
