Unpacking The Printer
Bar Code Verification
The most important consideration when printing a bar code is to ensure the 
bar code will be scanned properly. Incorporating a bar code quality procedure 
in the printing process is the best way to ensure that bar codes are being 
printed correctly. A properly implemented verification procedure will increase 
overall bar code quality, reduce waste from misprinted bar codes, and 
achieve high first time read rates, which is an increasingly important factor in 
newer, more efficient systems, where manually entered data is not acceptable 
as a back up function. Verification also minimizes the costs of returned 
products due to poor reading or unaccountable bar codes. 
RJS designs and manufactures the world’s most complete line of bar code 
verification products, including their portable Inspector and Laser Inspector 
models, On-Line Inspector and AutoScan II series. For more information on 
RJS bar code verifiers, contact their corporate headquarters at 562-994-0930, 
or visit their web site at www.rjs1.com.
Unpacking The Printer
The printer is shipped in a carton and protective bag. Keep all packing 
material in case you need to move or ship the printer again. Avoid touching 
the electrical connectors to prevent electrostatic discharge damage while 
setting up the printer.
CAUTION
The discharge of electrostatic energy that accumulates on the surface 
of the human body or other surfaces can damage or destroy the print 
head or electronic components used in this device.
CAUTION
Damage to the printer interface connector may result from placing the 
T4204 printer on its backside during unpacking or handling.
