Oki 80 Series User manual

i
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.

It is recommended that you set the printer or the language or character
set you use most. You can use a program command (see Page 3–9) to
change to another language within a document, so it is not necessary to
change these switch settings i you use more than one language.
Switch 6 is the automatic line eed selection. Be ore shipment, it is set to
OFF. I you discover that your text is being overprinted, it may be
because your computer does not send a line eed at the end o a line. In
that event, set this switch to ON and the printer will insert an automatic
line eed at the end o each line. I your computer automatically sends a
line eed at the end o every line you can use this eature to double space
a document by setting it to the ON position.
Switch 7 selects the slashed or unslashed zero ont. The slashed zero ont
should be chosen when it is important to distinguish between a zero and
a capital O. The switch is set to OFF to select the unslashed zero and to
ON to select the slashed zero.
Switch 8 selects the roll paper stand (RPS) or the cut-sheet eeder (CSF)
To select the cut-sheet eeder move this switch to the ON position.
