NOTE: Since the scan camera’s mirror is the surface deposition type and easily gets scratched, special care should
be paid to it when cleaning. Furthermore, organic solvent such as liquid cleaner should not be used.
NOTE: Be careful not to touch your finger or cotton swab directly to the LED lighting. The careless touch may
change the optical axis of lighting, causing vision recognition problem.
Cleaning of Fixed camera (M4e/M4s)
Remove dirt/dropped obstacles (components or deposits) in a gentle way from the half mirror/lens /lens
filter of the fixed camera, blowing air with a blower brush or wiping with a dry thing like a cotton swab.
Avoid applying your finger pressure directly to the lens and mirror through the use of such things as tissues.
For stubborn and sticky dirt such as grease, which cannot be cleaned away by air blow or wiping with dry
cotton swab, wipe it off with a moistened cotton swab with little amount of liquid cleaner, and finally with
dry one to remove the liquid cleaner and dirt completely. Do not apply the liquid cleaner directly on the half
mirror/lens/lens filter.

Remove the front cover of fixed camera
When two fixed cameras are set next to next, it would be difficult to clean the lens and lens filter because of
no clearance between the two cameras. In such case, remove the front cover beforehand as followings.
ACTION:
Loosen the four setscrews (hexagonal screw M3 x 6) fixing on the front cover. (You do not have to
remove the screws here.)

Pull the front cover to your side, and remove it.
When attaching the front cover, put it onto the lighting box of fixed camera so that the two slots on the
top and two slots on the side of the cover match with the setscrews, and tighten the setscrews to fix.
Slot for setscrew
NOTE: When attaching the front cover, set it at right position securely. If the set position is not proper or the
setscrews are not tightened enough, the cover may come off during operation, causing serious accidents.
Furthermore, if the cover is set in inclined way against the lighting box of fixed camera, vision recognition
may not be performed properly by effect of room lighting condition.

Cleaning of Teach Camera
The lens of teach camera faces downward, and usually it would not get any dirt/dust under the normal
operation. However, if it gets dirty, blow air using blower brush from the bottom of the teach camera in
order to remove the dust.
