Why do faxes received on my Oki C5550 MFP sometimes look distorted?
If faxes received on your Oki All in One Printer sometimes look distorted, it could be because the received document is wider or longer than the paper loaded in the tray. The machine automatically reduces the document's size to fit the paper. This issue might also be communication-related.
What to do if my Oki All in One Printer will not poll a remote machine?
If your Oki All in One Printer will not poll a remote machine, call the person at the remote machine to ensure they have loaded documents and that their machine is set to polling transmission mode.
Why was the received message completely blank after sending a fax from my Oki C5550 MFP?
Make sure that the document is loaded correctly before faxing with your Oki All in One Printer; with text face UP in the ADF or face DOWN on the glass.
