pressing the Paper Feed button.  Verify that paper advances correctly 
 
Note:  Paper Supply Roll -- To prevent any possible damage to the print head mechanism, it is 
important to verify that the paper has not been fastened to the inside core in any way. 
The paper should be wound on the core in such a way that the end of the paper will 
unwind freely from the core. If fastened by tape or glue, the core will be pulled into the 
mechanism causing jamming and possible gear damage. Proper paper roll supplies are 
available from Datamax-O’Neil, see Section 4.7
 for listing of part numbers. 
 
2.2  Tearing Paper 
The printer’s paper door acts as a tear bar. Pull one edge of the paper against the tear bar as 
indicated, then tear down and across against the tear bar to tear the paper. See Figure 8
 for 
details.

The tear bar may have sharp edges 
 
Note: Using the tear bar is the only way to tear the paper.  
 
Note: Pulling up and pulling sideways without using the tear bar can cause a paper jam due to 
paper misalignment in the print head mechanism
