Load media using the appropriate feed path (front, top, bottom or rear) and mount the on-board tractor feed unit front or rear as needed. Select the required emulation and font settings on the operator panel or via the printer driver. For multi-part printing, ensure correct alignment and that tractor pins are engaged for continuous forms. Replace the ribbon using the 'clean hands' changing mechanism to avoid delays and contamination.

Usage recommendations

For reliable long-term operation, use the recommended OKI ribbons and perform routine checks of tractor alignment and print head condition. Use Sleep mode to reduce energy consumption during idle periods and choose the appropriate paper path or optional tractor/roll stand for heavy media or continuous runs.
