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. 
•  Available memory may have been exceeded by the requirement of 
the label format. Try reducing the memory allocated to either the 
internal module or scaleable font caches; see System Settings / 
Memory Settings, Section 4.2.5. 
•  If using serial communications, ensure that the interface cable meets 
the requirements found in Section 3.3.1. 
Missing print on left or right 
side of the label: 
Information may be formatted outside the label dimensions. Check 
your software program label size or check the values in the menu for 
Print Control / Column Offset and Print Control / Custom Adjustments 
/ Column Adjust; see Section 4.2.3. 
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. 
No power (the display is 
‘Off’): 
• Verify that the AC power cord is connected to an outlet and to the 
printer; also, ensure the power switch is ‘On’. 
• Verify that the AC outlet is functioning, or try connecting the printer 
to different AC circuit. 
•  The AC cord may be damaged; replace it. 
• The line fuse may be blown; call for service. 
Nothing is printing (labels 
advance normally, but no 
image is printed) using direct 
thermal media:  
Test the labels to make sure they react to heat. 
If the labels do react to heat, try increasing the Heat setting (see 
Section 4.2.3); it may be too low. Make the adjustment in the software 
program or through the User Interface. (The same functional 
commands from the host computer may override the menu settings; see 
Section 4.2.6.) 
If the labels do not react to heat, replace the media being used with 
direct thermal stock.
