2 Printer installation
2.1 Installation position
Flatly place the printer on the operation table, which must be
waterproof, moistureproof and dustproof. The maximal tilted angle
should not exceed ±15° during installation.
2.2 Paper roll installation
1) Pull the cover open lever towards the front of the printer and turn
the top cover upward to open it (see figure 2.2-1);
2) Pull the left and right paper holders apart and load the paper roll,
then pull the front of paper roll out to spread it in the print path,
and push the paper under the paper guide (see figure 2.2-2);
turn the thumb wheel properly in the direction shown in the figure
to decrease the force on paper roll (see figure 2.2-3);
3) Ensure the paper is installed in the path correctly, and close the
top cover;
4) If the diameter of paper roll is very big, use the corresponding
tool to remove the paper holder baffles, then turn the baffles, and
insert them into the center holes of the left and right paper
holders along the guiding slot (see figure 2.2-4);
