Attaching Power

Attaching Power

Important • Set up your printer so that you 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

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.

Loading Roll Media

Placing the Roll in the Media Compartment

1.Open the printer. Remember that you need to pull the release latch levers toward the front of the printer.

2.Open the media roll holders. Pull the media guides open with your free hand and place the media roll on the roll holders and release the guides. Orient the media roll so that its printing surface will face up as it passes over the platen (drive) roller.

3.If your printer includes the moveable blackline sensor option, verify that the sensor is aligned in the center default position. This is the standard operating position for media sensing. When the sensor is moved from the default position, the printer will only detect blackline, black mark and notched marker media.

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 77 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 11.

Hooking Up the Printer and Computer

Hooking Up the Printer and Computer

The Zebra G-Series printers support a variety of interface options and configurations. These include: Universal Serial Bus (USB) interface, RS232 Serial, Parallel (IEEE 1284.4) and 10/100 Ethernet.

GX420 Printers

•USB, Serial and Parallel

•USB, Serial, and Ethernet

Caution • Keep the power switch in the OFF position when attaching the interface cable. The power cord must be inserted into the power supply and the power receptacle on the back of the printer before connecting or disconnecting the communications cables.

.

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.
