Section 1: QL Introduction Description The Zebra QL220, QL 220 Plus; QL320, QL 320 Plus; QL420 and QL 420 Plus Mobile Printer s are low-cost, portable, direct thermal printers. They can be carried by the shoulder strap, sit on a work space, or be mounted to a specific location. They are powered by a Li-Ion battery pack which makes them particularly useful in environments where AC power is not readily available.
Diagnostic Tools This section of the Printer Repair Manual contains instructions for using the various diagnostic tools available from Zebra and instructions on contacting technical support services offered by Zebra. Following sections contains explanations on the products configuration structure, troubleshooting guide for isolating common printer problems, illustrated parts breakdowns for specific models and specialized component replacement procedures.
Printing a Diagnostic Label Creating 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. Press and release the Power button and keep the Feed button pressed. When printing starts, release the Feed button.
Peripherals installed: In this example the LCD display option is installed. Flash and RAM Memory Installed Maximum Label Size Resident Human Readable fonts installed Figure 1a: Configuration L abel Example (continued) RMAN-QLS-002 rev.
Files Loaded in Printer Memory (will include Pre-scaled or Scalable Fonts) EPL and ZPL emulation is standard on QL Plus series Figure 1b: Configuration L abel Example (continued) • 1-9 • RMAN-QLS-002 rev.
Using Label Vista Label Vista is a program running under the Windows™ environment that allows users to design labels which can be printed on the full range of Zebra mobile printers. Label Vista also provides a powerful set of diagnostics tools which use familiar Windows “point and click” routines. These tools can be reached under the Printer selection on the Label Vista menu bar.
Using Label Vista Equipment Required 1. A computer with the following minimum configuration: • Pentium CPU • 256 MB RAM • 1.44 MB Floppy Drive • 1 GB Hard Drive • CD-ROM drive • SVGA 14 in.monitor and SVGA card • 2 Serial Ports • USB Port • Windows 95/9, NT or 2000 • Unit Test Software version 3.3 or higher installed with the “euro” configuration. 2. A bar code scanner, using either RS232 (serial) keyboard “wedge” or USB communications. (Example: Symbol Model LS1908 series) 3.
Section 2 • QL Repair Procedures Using the QL Product Configuration Code Each QL series printer has a 15 digit Product Configuration Code (PCC) label on the bottom of the unit. This code is explained by the charts for the respective printers in Section 3. When ordering replacement parts use the PCC code to ascertain the features installed on your printer. Then use the exploded view of the printer on the following pages to determine which replacement kits should be ordered.
Troubleshooting Standard Control Panel If the printer is not functioning properly, refer to the chart below to find the state of the two LEDs on the Control Panel. Then refer to the Troubleshooting topic referenced in the chart to resolve the problem.
