    • S
      Steven WatsonAug 26, 2025
      If your Oki Printer frequently experiences paper jams or feeds multiple sheets, consider the following: * Ensure the printer is placed on a stable, flat surface. * Use paper suitable for the printer, avoiding thick, thin, moist, folded, creased, or warped paper. Store paper properly. * Align the paper edges to the paper guides. * Load several sheets of paper. * Remove existing sheets of paper from the tray and add the new sheets to them, ensuring alignment and then load the tray. * Load postcards, envelopes, label sheets or transparencies in the Multi Purpose tray. Check and load in the correct orientation.
