Rev AA Checking and Replacing the Ribbon 5-11
Videojet DataFlex 6420 Operator Manual
3 Pull the two ribbon spools (one full of used ribbon) from the cassette
firmly, as shown in Figure 5-11. The discs that are situated under each
spool can be used to lever the spool off the cassette.
4 Discard the used ribbon and spools.
5 Open a new shrink-wrapped roll of ribbon, and unwind about 12
inches of ribbon (30 cm).
The spool holders on the cassette have different colored discs:
• The black disc is for the new roll of ribbon.
• The silver disk is for the empty roll.
When the printer is running, the new ribbon unwinds from the black
holder, and winds onto the silver holder.
6 Slide the full spool onto the holder that has a black disc. The roll
should be located such that the ribbon unwinds in the direction as
shown in Figure 5-12 on page 5-12.
Note: Ensure that the spool is pushed completely down onto the holder.
