OPERATOR CAUTIONS AND WARNINGS These pages describe general safety and maintenance procedures that an operator must follow. They are referenced throughout the service manual. The manual may include other warnings and cautions not displayed here.
Media Cautions & Tips 1) Always use high quality approved labels and tags. Approved supplies can be ordered from your dealer. 2) If poor quality, adhesive backed labels are used, that DO NOT lay flat on the backing liner, the exposed edges may stick to the label guides and rollers inside the printer, causing the label to peel off from the liner and jam the printer. 3) DO NOT use non-approved transfer ribbon. Permanent damage to the print head may result if a non-approved ribbon is used.

INTRODUCTION If you are a field engineer or technician, this manual helps you with routine maintenance, troubleshooting and procedures for replacing parts for repair. Follow the parts replacement procedures as closely as possible. If you are unsure of any procedure, please contact your service representative or call the products technical support group at Zebra Technologies Corporation, (805) 579-1800. Zebra Technologies stocks all replacement parts for the printer.
Models There are several models of the printer, each of which look similar but have different ribbon and media handling features. LP models print using direct thermal media only. The top case is flat. TLP models print using either direct thermal or thermal transfer media. The top case flares at the front to enclose the carriage and ribbon spool hubs. There are models that can handle up to four-inch (102 mm) wide media and those that can handle up to two-inch (51 mm) wide media.
Conventions This manual uses the following notations to call attention to important information. ICON / SYMBOL MEANING WARNING - critical safety information. CAUTION - problem avoidance messages. STATIC SENSITIVE - follow procedures that protect against the discharge of electrostatic energy that accumulates on the surface of the human body or other objects as this discharge can damage or destroy the print head and other electronic components. HEAT - The print head becomes hot while printing.
Environmental and Shock Protection Extreme temperature and humidity fluctuations or mishandling can damage the printer and power supply. Allow 30 minutes or more before opening the printer's plastic bag. This time allows the printer to stabilize temperature especially after storage in a cool, dry location and then placement in a warmer, more humid location. Warm, humid air condenses on the cool components of the printer and this condensation may damage the components. Move the printer carefully.
CLEANING AND MAINTENANCE The printers are manufactured and tested under a strict quality management program. Zebra Technologies uses only high quality components and materials in its printers. Although only minimal routine maintenance is required, following these simple maintenance guidelines will ensure longer life with quality printing performance. General Cleaning Keep the outside your printer clean by periodically wiping it with a soft cloth dampened with water.
Cleaning the Media Path Keep the inside of your printer clean as needed, by using a brush, vacuum or air blower along the media path (except the print head). If a label jams inside the printer, remove the label and any adhesive residue immediately. Adhesive may spread throughout the printer's media path if not completely removed. Many adhesive are permanent and have short "set" times.
Cleaning the Print Head When handled during installation, and over time, the print head may become contaminated resulting in poor print quality. After installing a new print head or after using a roll of media or ribbon, rub the cleaning pen across the dark area of the print head. Allow the print head to dry for one minute before loading labels. MOVIE Avoid touching the print head whenever possible.

TROUBLESHOOTING GUIDE PROBLEMS Status indicator does not light when power switch is on (I) Printer is in dump mode but nothing prints after sending file. SOLUTIONS 1. Check power connections from the printer to the outlet. 1. File does not contain a form feed code that will advance sheet. Press the Feed button to print data in the printer’s buffer. ASCII characters print 1. Printer may be in dump mode. Press the Feed button to reset to normal operation. in place of expected label art and bar 2.
PROBLEMS Printer appears to be working with the indicator light GREEN, but nothing is printed. SOLUTIONS 1. Check the connections between the printer and the cable as well as the cable and the computer. 2. Verify that the labels are the correct type. 3. Check the roll and verify that the print surface faces up for direct thermal printing. 4. Check that the transfer ribbon is correctly routed and has the ink side down. 5. Check print head wire bundle connections in carriage at main PCBA.
PROBLEMS SOLUTIONS The printer firmware is updated by way of the parallel port. Printer firmware must be updated. 980358-001 Rev. A 1. Use the download utility to send firmware to the printer. 2. Optionally, you can download from the c:\ prompt by typing copy/b filename lpt1: from the directory holding the update file. The printer's light should start flashing green-orange, and then every few seconds will flash red a couple of seconds. Once the update is done, the light goes dark then comes on green.
Print Head Wear The print head has a limited life and is considered a consumable item. The media rubs across the print elements and wears away the surface. Media material, operational settings, and environment all affect this process. Printing with worn elements may create illegible images. If the print quality remains poor after cleaning, you may need to replace the print head.
REQUIRED TOOLS Make use of the following tools while performing replacement procedures: • • • • • • • Phillips driver #0 Phillips driver #1 Phillips driver #2 Slot-head screwdriver tweezers needle-nose pliers pliers for integrated chips 980358-001 Rev.
