Present sensor not functioning, 
labels continue to print 
uninterrupted: 
• Present sensor switch in OFF position; Move present sensor switch to 
the ON position. 
  
• Present sensor disabled; Change the present sensor operation to 
enable using the Windows printer driver properties or Datamax Printer 
Configuration Utility (DMXConfig).  Ensure present sensor switch set to 
ON. 
 
Printer attempts to load with no 
media installed: 
• Debris in label edge sensor; Air blow out debris, clean with alcohol and 
lint free material. 
  
• Out of Stock setting is too low; Run Quick Media Calibration using 
Datamax Printer Configuration Utility (DMXConfig).   
  
• Out of Stock setting is too low; Increase OOS Maxvolt using Datamax 
Printer Configuration Utility (DMXConfig). 
 
Media not auto-loading while 
motor attempts to load: 
• Leading edge of media is rough, catching in Label Edge Sensor, or 
preventing label from engaging onto platen roller; Cut a clean leading 
edge at or just prior to leading edge of label.  Reinsert leading edge of the 
media into label guides, feed the media into the guides until motor begins 
to move. 
  
• Out of Stock setting is too low; Increase OOS Maxvolt using Datamax 
Printer Configuration Utility (DMXConfig). 
 
Media not auto-loading; motor 
makes no attempts to load: 
• Media inserted before printer ready; Remove media from label guides 
and reinsert. 
 
Erratic feeding: 
• Media sensor may require cleaning; the media sensor is located in the 
left media guide towards the front of the printer. 
  
• The printer may require Top of Form Calibration; Perform the Calibration 
Procedure via the DMXConfig program. 
 
Erratic printing (instead of the 
label format, strange characters 
are printed):  
• The printer may be in Hex Dump Mode; Unplug the printer for 5 seconds 
and then reconnect power. 
  
• If using the serial port for communicating, check both the host and 
printer port settings; the printer may be set to eight data bits while the host 
is set to 7 (or vice versa). 
 
Intellifont will not print: 
Intellifont format is Little/Big Endian specific. The printer uses Big Endian. 
 Refer to your font supplier for information. 
 
Light print on the label: 
• Printhead not latched; Press down on printhead to assure it is in its 
locked down position. 
  
• The Printhead Pressure may be incorrectly adjusted; click here to adjust. 
  
• The Printhead or Platen Roller may be dirty or worn; clean or call for 
service. 
 
• Incorrect Power Supply; be sure to only use the power supply shipped 
with the printer.
