Loading the ZD421 Ribbon Cartridge
The printer uses a transfer ribbon cartridge for thermal transfer printing. Just slide the cartridge into the
ribbon transport and close the printer. The printer reads cartridge information stored on the cartridge.
1. Insert the ribbon cartridge into the ribbon cartridge slot on the ribbon transport in your open printer.
Push until the cartridge is nearly flush to the front of the ribbon transport. You will hear and feel the
cartridge lock into place. Only Genuine Zebra Ribbon Cartridges are supported.
