Loading Thermal Transfer Roll Ribbon
The ZD621 and ZD421 thermal transfer printers have a flexible ribbon system. It supports 300 meter and
74 meter genuine Zebra
®
ribbons. The printer includes 300 meter ribbon adapters for non-Zebra ribbon
rolls. 74 meter ribbon from non-Zebra printers does not need the Non-Zebra ribbon adapters to operate
properly.
Transfer ribbons come in several varieties and in some cases colors to match your application needs.
Genuine Zebra
®
transfer ribbons are specifically designed for your printer and Zebra brand media. Using
non-Zebra media or ribbons not approved for use in your Zebra
®
printer may damage your printer or
printhead.
The media and ribbon types should be matched to provide you with optimal print results.
Always 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.
Always use an empty ribbon core that matches your transfer ribbon roll’s inner diameter (I.D.).
Ribbon wrinkling and other print problems can occur.
Your printer needs to use genuine Zebra
®
ribbons that have a ribbon out trailer (reflector) to stop printing
when roll of transfer ribbon has been used up. Genuine Zebra
®
ribbons and ribbon cores also include
notches used to maintain positive ribbon roll engagement and drive without slipping while printing.
Genuine Zebra
®
ribbons for this printer include:
Performance Wax
Premium Wax/Resin
Performance Resin for synthetics (6 ips max. speed) and coated paper (4 ips max. speed)
Premium Resin for synthetics (4 ips max. speed)
IMPORTANT: 74 Meter Ribbons - DO NOT USE early model desktop printer ribbon cores! The older style
ribbon cores (and some Non-Zebra ribbons) can be identified by notches on only one side of the ribbon
core. These older cores are too large.
IMPORTANT: DO NOT USE ribbon cores with damaged notches - rounded, frayed, smashed, etc. The
core notches should be square to lock the core on the spindle or the core may slip causing ribbon wrinkle,
poor end of ribbon sensing or other intermittent failures.
