SECTION
CLEANING THE CASSETTE MAPPING SENSOR
D
The cassette mapping sensor is the optical sensor on the robotic arm that senses
the presence of slides in the slide cassettes. The lens of it should be wiped clean
on a monthly basis or if cassette mapping errors occur (31--).
Note:
Clean the sensor when there are no cassettes in the Imaging Station.
Removing a partially processed cassette of slides could result in data
loss.
The sensor is located behind the robot shield. It is attached to the side of the
slide transfer arm. Refer to Figure 5-11.
Open the right hand door of the Imaging Station.
Gently rotate the robot shield to the left.

Locate the cassette mapping sensor. It is a round black object with a lens in the
center. If the Imaging Station power is on, a red light shines out of the sensor.
Clean the end of the sensor with a lens paper.
The robot shield may be returned to its original position or just left as is. At the
start of the new batch, it will automatically return to the correct position.
