Wipe the light diffuser plate with a
cotton swab.
The side-view camera diffuser plate is
attached to the lighting unit bracket on the

diffuser plate.

Reference
The side-view camera checks whether a component is
being picked up correctly at the nozzle tip by viewing it
from the side. Dirt or solder adhering to the nozzle tip
may cause recognition errors. When cleaning the
nozzles, refer to the earlier sections (1.1 and 1.2) in this
chapter.
