The quality of my fax is poor. What should I do?

  • See below.

    Sent Fax Quality is Poor

    If the sent fax quality is poor, try these solutions:

    • Clean the scanner glass.
    • Clean the ADF.
    • Try changing the resolution or density setting on the control panel.
    • Try changing the original type setting on the control panel.
    • If you are sending a monochrome fax to a single recipient, try sending the fax using the Direct Send feature.

      Note: If you send a high-resolution monochrome fax without using the Direct Send feature, the product may automatically lower the resolution.

    • Try enabling the error correction mode (ECM) setting.
