2D Code Checker and Condition Watcher
These functions show quantitatively how much leeway there is in the ability to take readings
and whether the suitable lighting and lens have been selected. These functions are not
displayed if a 2D code cannot be read. If reading is not possible, check the messages
displayed on the image monitor and use them to correct the system.

(ALM is dis-
played.)
Likely wrong lighting selection The contrast is too low and the situation is unlikely to be
corrected by changing the brightness of the lighting or the
aperture of the lens. Try changing the direction or color of
the lighting.
Make lighting brighter The contrast is low and the white portions are dark.
Increase the lighting or open the aperture of the lens.
Make lighting darker The contrast is low and the black portions are light.
Decrease the lighting or close the aperture of the lens.
Teach again. The shutter speed may be incorrect. Try teaching again.
Too many misidentified Cells The marked portion of the 2D code shown on the screen
cannot be discerned. Check the condition of the mark.
Likely defocusing Adjust the working distance or the focus of the lens.
Set 2D code center of view Follow the message.
Need to make the Cell size
larger
The dot size is too small. Decrease the field of vision or
increase the mark size of the 2D code.
Need to zoom out The code is too large for the field of vision. Increase the
field of vision of decrease the size of the mark for the 2D
code.
2D Code
Checker
(When read-
ing fails)
2D code is not found No shape thought to be a 2D code can be found in the
field of vision. Check the screen to be sure a 2D code is in
the field of vision.
2D code is not distinguished There are too many shapes in the field of vision that could
be 2D codes, so reading is not possible. Consider making
a consistently plain background for the 2D code.
Decode error The 2D code is of a format not supported by the 2D Code
Reader.
Timeout The read time set for the Read Timeout was exceeded,
causing reading to be ended. Change the time set for the
Read Timeout.
