Oki 80 Series User manual

IMPORTANT
You have just bought the best printer, so be sure to use only the ribbons
recommended for it. Original OKI ribbons are the only ones that the
manufacturers recommend. Ask for them by name.
Please remember that if you buy any other ribbon your arranty may be
invalidated.
Purchasing inferior ribbons really does not make sense. They do not last
as long. What is more, they are prone to shredding, hich can cause
damage to your printhead. Any short term savings on cheap ribbons are
quickly lost.
So do not aste your time and money . . . insist on OKI consumables for
your OKI printer.
You can order them from your printer supplier.
