14 Getting Started 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.
Getting Started 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.
16 Getting Started 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. 980611-001 Rev.
Getting Started Loading Roll Media 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 label web (gap) sensing area, the printer will only detect blackline, black mark and die-cut notched media. See Moveable Blackline Sensor Option on page 49 for more details on adjusting this sensor option.
18 Getting Started Loading Roll Media 4. Pull the media so that it extends out of the front of the printer. Verify the roll turns freely. The roll must not sit in the bottom of the media compartment. Verify that the media’s printing surface is facing up. 5. Push the media under both of the media guides. Under Media Guides 6. Close the printer. Press down until the cover snaps closed. 980611-001 Rev.
Getting Started 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 status 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.
20 Getting Started Pre-install Windows® Printer Drivers Pre-install Windows® Printer Drivers Zebra is changing the way you install and use your printer with your Windows based PC systems. We recommend that at minimum, the ZebraDesigner™ Windows® driver be preinstalled to take advantage of the advancements in ease of use and simplicity of the Windows operating systems since the release of Windows XP® SP2.
Getting Started Pre-install Windows® Printer Drivers Serial Port and Windows® operating systems The Windows operating system default settings for the serial port communication closely match the printer’s defaults settings with one exception; the data Flow Control settings. The Windows default data Flow Control setting is NONE. The G-Series printer requires data Flow Control set to Hardware.
22 Getting Started Connecting your Printer to a Computer Connecting your Printer to a 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.
Getting Started Connecting your Printer to a Computer USB Interface Requirements Universal Serial Bus (version 2.0 compliant) provides a fast interface that is compatible with your existing PC hardware. USB’s “plug and play” design makes installation easy. Multiple printers can share a single USB port/hub. When using a USB cable (not supplied with your printer), verify that the cable or cable packaging bears the “Certified USB™” mark (see below) to guarantee USB 2.0 compliance. .
24 Getting Started Connecting your Printer to a Computer Serial Communications The printer automatically detects and switches the serial port to match common serial port cabling and signal connection configurations for DTE and DCE communications. The required cable must have a nine-pin “D” type (DB-9P) male connector on one end which plugs into the mating (DB-9S) serial port located on the back of the printer. The other end of this signal interface cable connects to a serial port on the host computer.
Getting Started Connecting your Printer to a Computer EPL Y Command Use the serial port setup (Y) command to change the communications settings on the printer. 1. With the host computer set at the same communications settings as the printer, send the Y command to change the printer to the desired settings. Note: the Y command does not support setting the data flow control, use the Xon/Xoff setting. 2. Change the host computer settings to match the new printer settings.
26 Getting Started Connecting your Printer to a Computer Parallel Port The required cable must have a 25 pin “D” type (DB-25P) male connector on one and a Centronics on the end (IEEE 1284 A-B parallel interface specification). Early models of GSeries printers originally supported parallel cables with two 25 pin “D” type (DB-25P) male connectors on both ends (IEEE 1284 A-A parallel interface specification). Parallel Cable 980611-001 Rev.
Getting Started Connecting your Printer to a Computer Ethernet The printer requires UTP RJ45 Ethernet cable rated CAT-5 or better. For more information on configuring your printer to run on a compatible Ethernet based network, see the ZebraNet® 10/100 Internal Print Server manual. The printer must be configured to run on your LAN (local area network) or WAN (wide area network). The print server on board your printer can be accessed through the printer’s Web pages.
28 Getting Started After Your Printer is Connected After Your Printer is Connected Now that you have basic communication to your printer, you may want to test printer communications and then install other printer related applications, drivers or utilities. Testing Communications by Printing Verifying the print system’s operation is a relatively simple process. For Windows operating systems, the Zebra Setup Utility or the Windows ‘Printers and Faxes’ Control Panel to access and print a test label.
Getting Started After Your Printer is Connected Test Print with a Copied ZPL Command File for Non-Windows Operating Systems: 1. Create a text file with the following ASCII three characters: ~WC 2. Save the file as: TEST.ZPL (an arbitrary file name and extension name). 3. Copy the file to the printer. For DOS, a file sent to a printer connected to the system’s parallel port would be as simple as: COPY TEST.ZPL LPT1 Other interface connection types and operating systems will have different command strings.

32 Print Operations Determining Printer Configuration Determining Printer Configuration The G-Series™ printer uses a ZPL printer configuration status label to report the printer’s configuration status for both EPL and ZPL operations.The ZPL style label provides a more intuitive and functionally descriptive naming conventions than the EPL style printer status label. Operational status (darkness, speed, media type, etc.), installed printer options (network, interface settings, cutter, etc.
Print Operations Modes of Printing Modes of Printing You can operate this printer in many different modes and media configurations: • Direct thermal printing (which uses heat sensitive media to print). • Standard Tear-Off mode allows you to tear off each label (or batch print a strip of labels) after it is printed. • Label Dispense Mode: If an optional dispenser is installed, the backing material can be peeled away from the label as it is printed. After this label is removed, the next one is printed.
34 Print Operations Print Media Types Table 1 • Types of Media Roll and Fanfold Media Media Type Non-Continuous Roll Media How It Looks Description Roll media is wound on a core that can be 0.5 to 1.5 in. (12.7 to 38.1 mm) in diameter. Labels have adhesive backing that sticks them to a liner, and they are separated by gaps, holes, notches, or black marks. Tags are separated by perforations.
Print Operations Replacing Supplies Determining Thermal Media Types Thermal transfer media requires ribbon for printing while direct thermal media does not. To determine if ribbon must be used with a particular media, perform a media scratch test. To perform a media scratch test, complete these steps: 1. Scratch the print surface of the media with a finger nail or pen cap. Press firmly and quickly while dragging it across the media surface.
36 Print Operations Adjusting the Print Quality Adjusting the Print Quality Print quality is influenced by the heat (density) setting of the printhead, the print speed, and the media in use. Experiment with these settings to find the optimal mix for your application. Print quality can be set with the Zebra Setup Utility’s ‘Configure Print Quality’ routine. Note • Media manufactures may have specific recommendations for speed settings for your printer and the media.
Print Operations Media Sensing Media Sensing The G-Series™ printer has automatic media sensing capability. The printer is designed to continuously check and adjust media length sensing for minor variations. Once the printer is printing or feeding media, the printer continually checks and adjusts the media sensing to accommodate for minor changes in media parameters from label to label on a roll and from roll to roll of media.
38 Print Operations Printing on Fan-Fold Media Printing on Fan-Fold Media Printing on fan-fold media requires you to adjust the media guide’s stop position. 1. Open the top cover. Fan-Fold Media Path 2. Adjust the media guide stop position with the green thumb wheel. Use a piece of the fan- fold media to set the stop position. Rotate the wheel toward you to open the guides wider. Rotate the wheel away from you to make the media guide narrower. 980611-001 Rev.
Print Operations Printing on Fan-Fold Media 3. Insert the media through the slot at the rear of the printer. 4. Run the media between the media guide and roll holders. 5. Close the top cover. After printing or feeding several labels: If the media does not track down the center (moves from side to side) or the sides of the media (liner, tag, paper, etc.) are frayed or damaged when exiting the printer, then the media guides may need further adjustment.
40 Print Operations Printing with Externally Mounted Roll Media Printing with Externally Mounted Roll Media The G-Series printer accommodates externally mounted roll media similar to the printer’s support of fan-fold media. The printer requires the media roll and stand combination to have a low initial inertia to pull the media off the roll. The G-Series™ motor has 30% more torque than the Zebra® 2800™ Series desktop printers to provide improved media handling and speed.
Print Operations Fonts and Your Printer Fonts and Your Printer The G-Series™ printer supports your language and font requirements with a variety of internal fonts, on-board font scaling, international font sets and character code page support, Unicode support, and font download. The G-Series™ printer’s font capabilities are programming language dependent. The EPL™ programming language provides for basic bitmapped fonts and international code pages.
42 Print Operations Fonts and Your Printer Localizing the Printer with Code Pages The G-Series™ printer supports two sets of language, region and character sets for permanent fonts loaded into the printer for each printer programming language, ZPL and EPL. The printer supports localization with common international character map code pages. • For ZPL code page support, including Unicode, see the ^CI command in the ZPL programmer’s guide.
Print Operations Stand Alone Printing Stand Alone Printing Your printer can be configured to work without being attached to a computer. The printer has the ability to automatically run a single label form. One or more downloaded label forms can be accessed and run with a terminal or wedge device or a Zebra® KDU (keyboard display unit) to call a label form. These methods allow the developer to incorporate data input devices, such as scanners or weight scales, to the printer via the serial port.
44 Print Operations Sending Files to the Printer Sending Files to the Printer Graphics, fonts and programming files can be sent to the printer from the Microsoft Windows operating systems by using the Zebra Setup Utilities (and driver), ZebraNet™ Bridge or Zebra® ZDownloader found on the user's CD or at www.zebra.com. These methods are common for both programming languages and the G-Series printers. Print Meter The G-Series printer has the capability to report printhead maintenance alerts.

76 Maintenance Cleaning Cleaning When you clean the printer, use one of the following supplies that best suits your needs: Cleaning Supplies Order Quantity Intended Purpose Cleaning pens (105950-035) Set of 12 Clean printhead Cleaning swabs (105909-057) Set of 25 Clean media path, guides and sensors You can obtain cleaning supplies at www.zipzebra.com. The cleaning process takes just a couple of minutes using the steps outlined below.
Maintenance Cleaning Cleaning the Printhead Always use a new cleaning pen on the printhead (an old pen carries contaminants from its previous uses that may damage the printhead). Caution • The printhead becomes hot while printing. To protect from damaging the printhead and risk of personal injury, avoid touching the printhead. Use only the cleaning pen to perform maintenance. When you load new media, you can also clean the printhead. 1. Rub the cleaning pen across the dark area of the printhead.
78 Maintenance Cleaning Media Path Considerations Use a cleaning swab to remove debris, dust or crust that has built-up on the holders, guides and media path surfaces. 1. Use the alcohol in the cleaning swab to soak the debris to break up the adhesive. 2. Wipe the ridges to remove accumulated debris. 3. Wipe the inside edges of both edge guides to remove any built-up residue. 4. Wait one minute before closing the printer. Discard the cleaning swab after use.
Maintenance Cleaning Sensor Cleaning Dust can accumulate on the media sensors. 1. Gently brush away dust; if necessary, use a dry swab to brush away dust. If adhesives or other contaminates remain, use an alcohol moistened swab to break it up. 2. Use a dry swab to remove any residue that may be left from the first cleaning. 3. Repeat steps 1 and 2 as required until all residue and streaks are removed from the sensor. .
80 Maintenance Cleaning Platen Cleaning and Replacement The standard platen (drive roller) normally does not require cleaning. Paper and liner dust can accumulate without effecting print operations. Contaminates on the platen roller can damage the printhead or cause the media to slip or stick when printing. Adhesive, dirt, general dust, oils and other contaminates should be cleaned immediately off the platen.
Maintenance Cleaning 6. Make sure the bearings are on the shaft of the platen. 7. Align the platen with the gear to the left and lower it into the printer’s bottom frame. 8. Rotate the tabs back and snap them into place. Allow the printer to dry for one minute before closing the dispenser door, media cover or loading labels. Other Printer Maintenance There are no user level maintenance procedures beyond those detailed in this section.
82 Maintenance Replacing the Printhead Replacing the Printhead If you need to replace the printhead, read the procedure and review the removal and installation steps before actually replacing the printhead. Caution • Prepare your work area by protecting against static discharge. Your work area must be static-safe and include a properly grounded conductive cushioned mat to hold the printer and a conductive wrist strap for yourself.
Maintenance Replacing the Printhead 2. Pull the printhead forward and pull it free of the top case if necessary. 3. Unplug both bundles of printhead wires from their connectors. 1. Align the printhead to plug the left and right connectors into the wire bundles. 8/4/10 GX420d™ / GX430d™ User Guide 980611-001 Rev.
84 Maintenance Replacing the Printhead 2. Slide the printhead into the left side and jog it into the right side catch. Clean the print head as described under Cleaning the Printhead on page 77. 3. Reload media. Plug in the power cord, turn on the printer and print a status report to ensure proper function. See Printing a Test (Printer Configuration) Label on page 19 980611-001 Rev.
