Connect the power supply.
Re-connect loose cables.
Scanner cannot read the
bar code. Interface/power cables are
loose. Re-connect loose cables.
Scanner is not programmed
for the correct bar code type. Make sure the scanner is programmed to read the
type of bar code to be scanned.
Scan other bar code(s) and bar code types.
Incorrect communication
parameters. Set the correct communication parameters (baud rate,
parity, stop bits, etc.)
Bar code symbol is
unreadable. Check the symbol to make sure it is not defaced. Try
scanning similar symbols of the same code type.

Cycle power to the scanner. As the laser briefly
appears after power up, scan the
Continuous

code from
Trigger Options on page 3-5

Connect an interface cable which has an external
trigger jack, a push button trigger cable, and a power
supply to the scanner. You can purchase these cables
from Motorola, or make a similar one using the
scanner’s pinouts as a reference. See the specification
chapter for your MiniScan model for pinouts.
Using a momentary switch, short the scanner’s trigger
line to ground to activate the laser, then scan the
Continuous
option of the
Trigger Mode
parameter.
NOTE If after performing these checks the symbol still does not scan, contact the distributor or Motorola
Enterprise Mobility Support. See page xv for contact information.
