  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.

Why does the top margin increase with each page on my Oki Printer?
- T
  thomasreidSep 15, 2025
  If the top margin size increases with each page printed from your Oki Printer, it could be due to creeping text. This occurs when the number of lines per page in the software doesn't match the printer's setting. Adjust the software accordingly, or set LINES Per PAGE in the soft control panel to equal lines per page in your software.
