Attaching Power
Important • Set up your printer so that y ou 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.

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 Transfer Ribbon
Transfer ribbons come in several varieties and in some cases colors to match y our application
needs. Zebra brand transfer ribbons are specifically designed for your printer and Zebra brand
media. Using non-Zebra brand or media or ribbon not approved for use in your Zebra printer
may damage your printer or printhead.
• The media and ribbon types should be matched to provide y ou with optimal print results.
• Alway s use ribbon that is wider than the media to protect the printhead from wear.
• For direct thermal printing, do not load ribbon in the printer.
Your printer needs to use Zebra Uni-Ribbons (universal ribbon). Uni-Ribbons have a ribbon
out trailer (reflector) to stop printing when empty. Zebra Uni-Ribbons will work on older
model Zebra desktop printers too.
Uni-Ribbons are identified with a color coded leader.
