1.4 Choosing a Place for the Printer
When selecting a place to set up your printer, choose a convenient location that provides the
following:
1. A flat, stable surface.
2. Adequate room around the printer to allow easy operation and maintenance. Make sure it’s close
enough to the computer for the printer cable to reach, and be sure you can easily unplug the power
cord.
3. Moderate environmental conditions. Select a cool, dry area and protect your printer from direct
sunlight, excessive heat, moisture, or dusty.
4. Appropriate power source. Make sure you use a grounded outlet; do not use an adapter plug. Avoid
electrical outlets controlled by timers or wall switches; an interruption in power can wipe out the
information in your computer or printer memory.
If you place the printer on a stand, follow these guidelines:
1. Use a stand that supports at least 9 kg (19 lb).
2. Never use a stand which is slant. Always keep it level.
3. Provide enough clearance below the stand and between the printer rack and the legs of the rack so
the tractor paper flows smoothly.
4. Place cables so they do not interfere with paper feeding; secure them to a leg of the stand if
possible.
1.5 Installing the Ribbon Cartridge
1. Before installing the ribbon cartridge, make sure the printer is turned off.
Note: Never replace the ribbon cartridge when the printer is connected with power. Printer may
start to work suddenly which may hurt you.
2. Open the printer window. (As shown below)

you have just used the printer, let the print head cool for a few minutes before you
touch it.
5. Please push out the ribbon nip according to the label on the ribbon cartridge.
6. Hold both sides of the ribbon down firmly to fit the plastic hooks into the printer slots. Then put the
ribbon nip between print head and ribbon guide slice, press it down until it click into place. (shown as
figure 1-6)
7. Turn the ribbon knob in the direction of the arrow to remove any slack from the ribbon so it is easier
to install.
8. Slide the print head from side to side several times to make sure it moves smoothly.
9. Please put the gap adjust lever to original place and close the window after the ribbon cartridge is
installed.
NOTE: 1. When your printing becomes faint, you need to replace the ribbon cartridge. Otherwise,
the print quality would be affected and the print head may be damaged.
2. To remove the old ribbon cartridge, first make sure the power is turned off, move the
print head to the center of the printer. Then grasp the ribbon cartridge handle on
either side and lift it out of the printer.

1.6 Connecting the Power Cord
1. Make sure the printer’s power is turned off. (O mark on the power switch is pressed down)
2. Make sure the voltage required by the printer matches that of your electrical outlet.
3. Plug one end of the power cord into the printer’s power supply inlet. (As figure 1-7 shown)
4. Plug the other end of the power cord into a properly grounded electrical outlet.
Note: 1. If the rated voltage and your outlet voltage do not match, contact your dealer for
assistance. Do not plug in the power cord.
2. Adopt the electrical outlet connecting the ground properly.
1.7 Printer Self-test Function
The built-in self-test function demonstrates that the printer is working properly. You can run the test with
either tractor paper or cut sheets; this section describes the easier way, with cut sheets.
Note: You should use paper at least 210 mm (8.3 inches) wide to run the self-test; otherwise, the
print head would print directly on the platen.
1. Make sure the printer is turned off and the paper-select lever is at the cut sheet position. Raise the
back cover.
2. While holding down the TEAR key, turn on the printer. The Paper Out and ONLINE LEDs blink
which indicates the printer is out of paper.
3. Adjust the right paper guide of the back cover to the range of the scale. Then adjust the left paper
guide to make the distance match the width of the print paper (as shown below).
