Introduction

The LS4278 scanner combines excellent scanning performance and advanced

ergonomics to provide the best value in a lightweight laser scanner. Whether used as a

hand-held scanner or in hands-free mode in a stand, the scanner ensures comfort and

ease of use for extended periods of time. Before programming the scanner, scan the

appropriate bar code(s), beginning on page 6, to communicate with the host.

Beeper Definitions

The scanner issues different beep sequences and patterns to indicate status. The table

below defines beep sequences that occur during both normal scanning and while

programming the scanner.

Beeper Sequence Indication

Standard Use

Low/medium/high beeps Power up.

High beep A bar code symbol was decoded (if decode beeper is enabled).

Four long low beeps A transmission error was detected in a scanned symbol. The

data is ignored. This occurs if a unit is not properly configured.

Check option setting.

Five low long beeps Conversion or format error.

Low/high/low beeps ADF transmit error.

High/high/high/low beeps RS-232 receive error.

Parameter Menu Scanning

Long low/long high beeps Input error, incorrect bar code or “Cancel” scanned, wrong en-

try, incorrect bar code programming sequence; remain in pro-

gram mode.

High/low beeps Keyboard parameter selected. Enter value using bar code key-

pad.

High/low/high/low beeps Successful program exit with change in the parameter setting.

Long low/long high/long low/long high

beeps Out of host parameter storage space. Scan Set Defaults on

page 6.

Wireless Operation

High/low/high/low beeps Pairing bar code scanned.

LED Definitions

In addition to beeper sequences, the scanner communicates with the user using a two-

color LED display. The table below defines LED colors that display during scanning and

charging.

Low/high beeps Bluetooth connection established.

High/low beeps Bluetooth disconnection event.

Long low/long high beeps Page timeout; remote device is out of range/not powered.

Long low/long high/long low/long high

beeps Connection attempt was rejected by remote device.

Code 39 Buffering

High/low beeps New Code 39 data was entered into the buffer.

Three long high beep Code 39 buffer is full.

Low/high/low beeps The Code 39 buffer was erased or there was an attempt to

clear or transmit an empty buffer.

Low/high beeps A successful transmission of buffered data.

Host Specific

USB only

Four high beeps Scanner has not completed initialization. Wait several sec-

onds and scan again.

Scanner gives a power-up beep after

scanning a USB Device Type. Communication with the bus must be established before the

scanner can operate at the highest power level.

This power-up beep occurs more than

once. The USB bus may put the scanner in a state where power to

the scanner is cycled on and off more than once. This isnormal

and usually happens when the host PC cold boots.

RS-232 only

High beep A <BEL> character is received and Beep on <BEL> is enabled.

Scanning LED Indication

Green Flash A bar code was successfully decoded.

Charging LED Indication

Green - Slow Continuous Flash Non-critical battery temperature fault.

Beeper Sequence Indication

Troubleshooting

Green - Fast Continuous Flash Scanner is charging.

Green - Solid Scanner is fully charged.

Amber - Continuous Flash Critical battery temperature fault.

Problem Possible Cause Possible Solutions

LED indicates a battery

temperature fault. Battery is above or below

normal operating tempera-

ture.

Do not use the scanner. Move the scanner to a

location within normal operating temperature.

The scanner can remain in the cradle while the

battery warms or cools to normal operating

temperature. Refer to the Product Reference

Guide for more information.

Nothing happens when

the trigger is pulled. No power to the scanner. Battery may be discharged; charge scanner in

cradle.

Check that battery door is closed

Ensure that end cap to battery chamber is se-

cured.

Scanner is disabled. Some host interfaces (e.g., Synapse, IBM-

468x) can disable the scanner. If this applies,

enable the scanner via the host interface.

Laser comes on, but sym-

bol does not decode. Scanner is not pro-

grammed for the correct

bar code type.

Ensure the scanner is programmed to read the

type of bar code scanned.

Refer to the Product Reference Guide for more

information.

Bar code symbol is unread-

able. Check the symbol to ensure it is not defaced.

Try scanning test symbols of the same bar code

type.

Distance between scanner

and bar code is incorrect. Move the scanner closer to or further from the

bar code.

Symbol is decoded but

not transmitted to the

host.

Cradle is not programmed

for the correct host inter-

face.

Check scanner host parameters or edit options.

Scanner not paired to

host-connected interface. Pair the scanner to the cradle (using PAIR bar

code on the cradle).

Interface cable is loose. Ensure all cable connections are secure.

Cradle has lost connection

to host.

In this exact order: disconnect power supply;

disconnect host cable; wait three seconds; re-

connect host cable; reconnect power supply;

reestablish pairing.

Programming Bar Codes

Following are some frequently used programming bar codes.

Note: For additional host types, refer to the LS4278 Product Reference Guide,

p/n 72E-69834-xx, available on the LS4278 CD, or on the Symbol website:

http://www.symbol.com/manuals.

Set Defaults

Scan SET DEFAULTS to set all parameters to their default values.

SET DEFAULTS

Scanning Modes

Scan the appropriate bar code below to determine the scanning pattern.

•SINGLE LINE ONLY - No up and down scan line movement (no raster).

•MULTI-LINE SMART RASTER - The scan line begins as a single line and moves up

and down (rasters) when a partial scan of a bar code is detected, or no bar code is

decoded 500 ms after the trigger is pulled.

•MULTI-LINE ALWAYS RASTER (default) - Rastering (up and down scan line

movement) begins immediately.

SINGLE LINE ONLY

Scanned data is incor-

rectly displayed on the

host.

Scanner is not pro-

grammed to work with the

host.

Ensure proper host is selected.

Check the scanner’s host type parameters or

editing options.

• For RS-232, ensure the scanner’s

communication parameters match the

host’s settings.

• For a keyboard wedge configuration,

ensure the system is programmed for the

correct keyboard type, and the CAPS

LOCK key is off.

Ensure editing options (e.g., UPC-E to UPC-A

conversion) are properly programmed.

Refer to the Product Reference Guide for more

information.

Scanning Modes (continued)

MULTI-LINE SMART RASTER

MULTI-LINE ALWAYS RASTER (Default)

Host Types

If a Synapse cable is used (i.e., part number STIxx-xxxx), the scanner autodetects the

Synapse cable and there is no need to scan bar codes to enable the Synapse host.

If a USB interface is used, the scanner autodetects the USB and defaults to the HID

keyboard interface. See page 11 to select the IBM hand-held host type.

If a Keyboard Wedge, RS-232, Wand Emulation, Scanner Emulation, or IBM 46XX is

used, the appropriate host type must be scanned. Select the appropriate host type from

the bar codes that follow.
