Inspection and maintenance
Camera lens
Check for dirt and grime on the camera lens, half-mirror and lighting unit.
To clean, use a cleaning stick supplied with the machine or similar cotton
swab, slightly moistened with alcohol, and gently wipe the surface of the
lens or mirror. If component chips or debris are on the lens or half-mirror,
remove them.

CAUTION
Do not apply excessive force to the camera as this may adversely affect the optical axis,
making the vision parameter settings unreliable.
Feeder
Check that all feeders are securely set on the feeder plate. For daily
inspection of feeders, see the FEEDER user’s manual.
Feeder plate
Check that no chips, debris and solder are on the feeder plate. Clean the
feeder place if necessary.

every 6 months) are essential to ensure safe and efficient use of the ma-
chine. We recommend setting an earlier inspection interval if parts are
subject to frequent usage. For detailed information on inspection methods,
refer to the separate Maintenance Guide (Basic).
