Menu Item  Details 
TEST SCANNER 
 
Tests the Linear Scanner, where: 
 
ALIGNMENT TEST 
 
Reads a bar code then displays the decoded data, the 
code type and scan count, repeating.  
SCAN TEST 
 
Reads a bar code then displays the decoded data, the 
code type and scan count, non-repeating. 
TEST RFID 
 
Tests RFID, where: 
 
TAG DATA 
 
Reads the data encoded on an RFID tag. 
 
DEVICE VERSION 
 
Displays the type and version of the encoding device. 
 
TAG ID – HF ONLY 
 
Reads then displays the High Frequency Tag ID 
number. 
 
 
PRINT TEST RATE (min) 
 
Allows a label-to-label delay when batch printing Test 
Labels, where:  
000  (0 – 120) 
 
Is the selected interval, in minutes. 
 
 
 
SENSOR READINGS

(THR), media “gap” (TRAN)  or “reflective” (REFL) 
sensor, ribbon sensor (RIBM), 24VDC power supply 
sensor (24V), present sensor (PS), printhead assembly 
sensor (HD), and printhead ranking resistor (RANK).
