Turn on the printer by pressing Power button and test the paper advance function by 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 Extech. See
Section 4.7
for listing of printer
supplies for Extech part number.
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.
FIGURE 8: TEARING PAPER
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
