Missing information in the printed 
label: 
• Check the label format for character placement outside the dimensions 
of the label; all row/column values must allow enough space for the 
height/length of the characters and bar codes to be printed within the 
format size. 
  
• The available memory may have been exceeded by the memory 
requirement of the label format. Try reducing the memory allocated to 
either the internal module or scaleable font caches. 
  
• If using serial communications, ensure that the interface cable meets the 
requirements found in the Printer Specifications section. 
 
Missing print on left or right side 
of the label: 
Information may be formatted outside the label dimensions. Check your 
software program or driver label size settings. 
 
Nothing is printing (labels 
advance normally, but no image 
is printed):    
• Verify that the media was properly loaded per the Loading Media 
section.   
  
• The heat setting may be too low. Make an adjustment in the software 
program or through the Windows printer driver.  
  
• Be sure you are using Direct Thermal Media. Contact a Media 
Representative. 
  
• The printhead or printhead cable may be loose; unplug the printer then 
reconnect. 
 
Nothing happens when trying to 
print using a software program: 
• Ensure that the printer is selected in the applications 'Print Dialog 
Window'. 
  
• Ensure that the printer is ready and not in an alarm state. 
  
• Ensure the interface cable meets the requirements found in the  Printer 
Specifications section. 
 
Poor print quality: 
• The printhead may need cleaning. 
  
• Adjust the Heat and Print Speed settings through the Windows Driver. 
  
• The media you are using may not be compatible; contact a Media 
Representative. 
  
• The Printhead Pressure may be incorrectly adjusted; click here to adjust. 
  
• The Platen Roller may be dirty or worn; clean or call for service. 
  
• The Printhead Burn Line may need adjusting; call for service. 
 
Skips labels when printing: 
• Media Calibration may be needed; Perform the Calibration Procedure 
via the DMXConfig program. 
  
• The label format may be within 1/8 inch of the label’s trailing edge. Try 
reducing the size or move the format slightly. 
  
• The Printer may be configured for 'Continuous Media' instead of Gap, 
Die-Cut, or Reflective. 
 
Unable to print rotated text: 
The characters may be formatted outside the label dimensions. Ensure 
the row/column values provide enough room for the height of the 
characters or bar code to be printed. See the Class Series Programmer’s 
Manual for details.
