Loading Ribbons
4) Place the re-transfer ribbon with the supply
shaft on the left and the take-up shaft on the
right, and their protrusions facing you and their
openings facing away from you.
5) Insert the open end of the take-up shaft into
the hole provided in the cartridge (for ease of
work, we recommend holding the shaft by
inserting your index finger into its open end),
and snap the protrusion at the other end of
the shaft into the cut-off in the cartridge.
6) In a similar way, put the supply shaft into the
re-transfer ribbon cartridge.
7) Turn the take-up shaft clockwise to take up
ribbon slack.
NOTE
If you perform the next step without taking up ribbon slack, there is a chance that the ribbon might
be broken.
8) Mount the re-transfer ribbon cartridge in the
P-55 itself.
When mounting the ribbon cartridge, push it
directly and slowly. If you try to force it in
slantwise, there is a chance that the ribbon
might be broken. If the ribbon clogs
somewhere, take out the cartridge, take up
ribbon slack again, and slowly re-insert the
cartridge.
