Important • Set up your printer so that y ou can handle the power cord easily if needed. To
make certain the printer cannot carry electrical current, you must separate the power cord
from the power supply receptacle or AC electrical outlet.
Caution • Never operate the printer and power supply in an area where they can get wet.
Serious personal injury could result!
1. Make sure the printer’s power switch is in the off position (down).
2. Insert the AC power cord into the power supply.
3. Plug the other end of the cord into an appropriate AC electrical outlet. Note: The active
power light will go on if power is on at the AC outlet.
4. Insert the power supply’s power connector into the printer’s power receptacle.

Loading Roll Media
When you load media, you must place the roll onto the media hangers.
You must use the correct media for the type of printing you require.
Preparing Media
Whether your roll media is inside or outside wound, you load it into the printer the same way.
• Remove the outside length of media. During shipment, handling, or storage, the roll may
become dirty or dusty. Removing the outside length of media avoids dragging adhesive or
dirty media between the printhead and platen.

Printing a Test (Printer Configuration) Label
Printing a Test (Printer Configuration) Label
Before you connect the printer to your computer, make sure that the printer is in proper
working order.
You can do this by printing a configuration label.
1. Make sure the media is properly loaded and the top cover of the printer is closed. Then,
turn the printer power on if you have not already done so. If the printer initializes with the
status light blinking green (pause mode), press the Feed button once to set the printer in
Ready (to print) mode. See the Troubleshooting on page 59 if the printer’s status light
does not turn solid green (Ready).
2. Press the Feed button two to three times to allow the printer to calibrate the printer for the
installed media. The printer may feed several labels during this process.
3. When the status light is solid green, press and hold the Feed button until the status light
flashes once.
4. Release the Feed button. A configuration label will print.
If you cannot get this label to print, refer to Getting Started on page 9.

GX printer models for more interface options.
GK420 Printers
• USB and Serial

Important • This printer complies with FCC “Rules and Regulations,” Part 15, for Class B
Equipment, using fully shielded data cables. Use of un-shielded cables may increase radiated
emissions above the Class B limits.
Interface Cable Requirements
Data cables must be of fully shielded construction and fitted with metal or metallized
connector shells. Shielded cables and connectors are required to prevent radiation and
reception of electrical noise.
To minimize electrical noise pickup in the cable:
• Keep data cables as short as possible (6 foot [1.83 m] recommended).
• Do not tightly bundle the data cables with power cords.
• Do not tie the data cables to power wire conduits.
