Cleaning of Scan Camera

Remove dirt/dust in a gentle way from the lens and mirror of the scan 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 lens and mirror.

no clearance between the two cameras. In such case, remove the front cover beforehand as followings.

ACTION:

① Loosen the four setscrews (hexagonal screw M3 x 6) fixing on the front cover. (You do not have to

remove the screws here.)

② Pull the front cover to your side, and remove it.

③ 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.
