Soft Keys Programmable LCD Settings In addition to the status icons, the LCD control panel can display other printer settings and functions as text. Applications can be written to allow the user to view and /or modify these settings using the scroll and select keys on the display. The menu that comes with the printer provides access to the most commonly used parameters.
Verify the Printer Is Working Before you connect the printer to your computer or portable data terminal, make sure that the printer is in proper working order. You can do this by printing a configuration label using the “two key” method. If you can’t get this label to print, refer to “Troubleshooting”. Printing a Configuration Label 1. Turn the printer off. Load the media compartment with journal media (media with no black bars printed on the back) 2. Press and hold the Feed Button. 3.
Cable Communication Caution • The printer should be turned off before connecting or disconnecting a communications cable. The QLn320 printer can communicate by cable; the specific cable supplied with your printer will vary with the host terminal and your model printer. RS-232C Communications The 14-pin serial connector on your communications cable plugs into the serial communications port on the side of the printer. QLn320 model printers also have a USB port.
other end of the cable must be plugged into the host terminal as shown in Figure 18, or to a serial or USB port on a computer (Figure 18). The QLn320 series is configured with the USB Open HCI interface driver allowing it to communicate with Windows® based devices. USB drivers are included in the Zebra Designer Driver which can be downloaded from the Zebra Web site. Other terminals or communications devices may require the installation of special drivers to use the USB connection.
Figure 20: Communications Port Strain Relief Rotate locking cap in a clockwise direction to lock cable in place.
Wireless Communications with Bluetooth™ Bluetooth is a worldwide standard for the exchange of data between two devices via radio frequencies. Bluetooth radios are relatively low powered to help prevent interference with other devices running at similar radio frequencies. This limits the range of a Bluetooth device to about 10 meters (32 feet). Both the printer and the device it communicates with must follow the Bluetooth standard.
WLAN Overview QLn320 printers can be equipped with a radio using the industry standard 802.11 protocols. They will have the FCC ID number on the serial number label on the back of the unit. • QLn320 series Wireless Network Printers with the Zebra 802.11 WLAN radio module can be identified by the text “Wireless Network Printer” on the serial number label on the back of the printer.
Using the Accessories Swivel Belt Clip Refer to Figure 21. Most QLn320 printers have a belt clip (p/n P1024458) installed as a standard feature. To use: hook the clip over your belt, and ensure that the clip is securely attached to the belt. The belt clip will pivot to allow you to move freely while wearing the printer. In order to install or remove the Belt Clip you will need to remove the battery pack.
Adjustable Shoulder Strap Refer to Figure 22 if your printer is equipped with the shoulder strap option (p/n P1028227). Insert each end of the shoulder strap into the cut-outs in each top corner of the printer and secure the looped end over the button on the end of the strap to fasten. Hold the buckle and pull the strap as shown below until you achieve Figure 22: Using the Optional Shoulder Strap Pull Strap here to lengthen. Hold Buckle. Pull Strap here to shorten. Insert loop into cut-outs on printer.
the desired length. Hand Strap The QLn320 hand strap accessory (p/n P1028226) attaches to the printer’s cut-outs as does the shoulder strap to provide the user with a convenient and secure method of carrying the printer. To attach the hand strap to the printer: • Insert the end of the strap through the cut out on the front of the printer as shown. • Loop the end of the strap back around the cut out and secure it over the button. • Repeat this process for the opposite end of the strap.
Preventive Maintenance Extending Battery Life • Never expose the battery to direct sunlight or temperatures over 104° F (40° C). • Always use a Zebra charger designed specifically for Lithium-Ion batteries. Use of any other kind of charger may damage the battery. • Use the correct media for your printing requirements. An authorized Zebra re-seller can help you determine the optimum media for your application. • If you print the same text or graphic on every label, consider using a pre-printed label.
QLn320 Cleaning Area Method Printhead (Figure 24) Use the supplied cleaning pen or 70% Isopropyl alcohol on a cotton swab to clean the print elements from end to end (the print elements are located in the thin gray line on the printhead). Platen Roller (Figure 24) Rotate the platen roller and clean it thoroughly with the cleaning pen or 70% Isopropyl alcohol and a cotton swab. Platen Roller (Figure 25) Units with linerless platens: Rotate platen & clean bearing points only.
