3.Holding ribbon cartridge with knob fac- ing up and ribbon sheild facing platen, fit grooves on either side at back end of cartridge over pins on ribbon plate.

4.Lower front of cartridge over printhead until it snaps into place, then turn knob in direction of arrow (clockwise) to take up ribbon slack.

5.The headgap lever by the side of cartridge adjusts for different paper thicknesses. Set it for the number of sheets in the forms you’re using from 1 to 4; use set- ting 5 for envelopes or extra-thick pa- per. Adjust the setting up or down for the best print quality.

Note: When the setting is set at 2~5, the printer automatically slows down for better print quality with thicker multipart forms.

Important! Be sure to use only ribbons specifically for use with MICROLINE 790 series.

For best results, use genuine OKI ribbons.
