„ Installation Procedure
Use the mounting holes in the side panel of the BL-700.
z When bracket is not used
* Prepare M3 nuts and screws according to the wall thickness on which
the BL-700 is mounted. (Screws provided are used when the bracket
is used.)
* As for dimensions of the mounting holes, see the dimension drawing.
* To suppress the noise from the device, be sure to apply insulation to
the mounting part of the BL-700 Series and the device.
z When the bracket is used
For vertical scan:
For horizontal scan:
* Prepare the set M4 screws for fixing the bracket to the machine or fac-
tory at your end.
* For dimensions of the bracket, see the external dimension drawing.
* Influence by noise from the bracket can be suppressed by installing
the insulation spacers.

„ Mounting angle and distance
Locate the BL-700 at the angle and distance shown below.
Determine the angle and distance, referring to the range and angle
characteristics shown in the user’s manual. The scanning distance
and angle may vary according to the narrow bar dimensions of a bar
code, size of a bar code and printing quality of a bar code.
Finally determine the setting after scanning the bar code to be used
actually.

Scan distance
Panel surface
*Scan distance = 230 mm (BL-700/701)
400 mm (BL-740/741)
500 mm (BL-780/781)
Do not locate the laser beam of the BL-700 at a
right angle to the bar cord surface to be scanned.
Otherwise, the scanning will be adversely
affected by influence of opposite reflection.
An optimum scan position can be determined by
using the reading rate test mode. As for the test mode
operation procedure, refer to the user’s manual.
