Installing Ink Ribbon
NOTE: WHEN THIS MACHINE IS TURNED ON FOR THE FIRST TIME,
A PAXAR FIELD ENGINEER MUST BE PRESENT.

(Threading path)
The ink ribbon comes pre-packaged in a plastic bag. For best results, leave the ink
ribbon wrapped in this bag until you are ready to use it in the printer. Use the
procedure and diagram below for loading the ink.
1) Unwrap the ink ribbon and put it on the ink-ribbon supply arbor (Figure 2) by
pressing it on to the arbor when the three slots are lined up.
2) Make sure the ink ribbon comes off the roll in the direction shown below and is
threaded as illustrated (see Figure 2).
NOTE: A new ink ribbon has a leader which makes it easier to use when threading
the ribbon through the print area.
3) Put an empty ink-ribbon take-up core on the ink-ribbon take-up arbor. The ink
take-up core must be at least as wide as the ink supply. The tape on the supply
roll of ink will be used to fasten the leader to the core.
4) Advance the ink until the leader starts to wrap around the take-up core.
5) Lower the take-up arbor into place. You will have to rotate the ink arbor as the
swing arm is returned to the drive roller to keep excess slack ink from between
the print head and the take up roller.
NOTE: Make sure that the ink-ribbon take-up core and the ink-ribbon supply roll
are against the edge guide plate so that the ink ribbon tracks straight through the
print station.
