Zebra LI4278 Product Reference Guide

3 - 6 LI4278 Product Reference Guide
Linear imager scanner emits five low
long beeps.
Conversion or format error. Check ADF rules for the host.
Linear imager scanner emits a
power-up beep after scanning a
USB device type.
Communication with the bus was
not established.
Communication with the bus must be
established before the linear imager
scanner can operate at the highest
power level.
Power-up beep occurs more than
once.
The host PC performed a cold
boot.
The USB bus may put the linear imager
scanner in a state where power to the
linear imager scanner is cycled on and
off more than once. This is normal and
usually happens when the host PC
cold boots.
Decoding Bar Codes
Linear imager scanner projects red
illumination, but does not decode the
bar code.
Linear imager scanner is not
programmed for the correct bar
code type.
Program the linear imager scanner to
read that type of bar code. See
Chapter 11, SYMBOLOGIES .
Bar code symbol is unreadable. Scan test symbols of the same bar
code type to determine if the bar code
is defaced.
Distance between linear imager
scanner and bar code is incorrect.
Move the linear imager scanner closer
to or further from the bar code. See
Decode Ranges on page 2-8 .
The scan line is not crossing
every bar and space of the
symbol.
Move the symbol until the scan line is
within the acceptable aiming pattern.
See
Figure 2-1 on page 2-6 .
Linear imager scanner decodes bar
code, but does not transmit the data
to the host.
Linear imager scanner is not
programmed for the correct host
type.
Scan the appropriate host type
programming bar code. See the
chapter corresponding to the host type.
Interface cable is loose. Ensure all cable connections are
secure.
Cradle is not programmed for the
correct host interface.
Check linear imager scanner host
parameters or edit options.
Linear imager scanner not paired
to host-connected interface.
Pair the linear imager scanner to the
cradle by scanning the
PAIR bar code
on the cradle.
Cradle has lost connection to
host.
In this exact order: disconnect power
supply; disconnect host cable; wait
three seconds; reconnect host cable;
reconnect power supply; reestablish
pairing.
