Why is my Oki All in One Printer not dialing out when connected to a PBX?

What to do if my Oki C5550 MFP All in One Printer is set for delayed transmission but it did not send?
If your Oki All in One Printer is set for delayed transmission but didn't send, check the display to ensure the printer's date and time settings are accurate.
Why is the image of received fax very poor on my Oki All in One Printer?
If the image quality of received faxes is poor on your Oki All in One Printer, try making a copy of a document on your local machine to ensure it is working correctly. You can also contact the sender and ask them to adjust their fax quality and density settings, make a copy of the document on their machine, and resend the fax.
Why will my Oki C5550 MFP All in One Printer not answer the telephone or receive faxes?
If your Oki All in One Printer won't answer the phone or receive faxes, first check that the power cord is properly connected. Also, verify the reception mode setting; the printer won't automatically receive faxes if manual receive mode is enabled.
Why is the image of the document printed by the remote machine very poor when faxing with Oki C5550 MFP?
If the image of the document printed by the remote machine is very poor when faxing with your Oki All in One Printer, it may be due to telephone line interference. Try adjusting the fax quality and density settings. To assess how the document will transmit, copy it on your machine. Also, try sending the document again later.
How to stop Oki All in One Printer from answering before the external telephone?
If your Oki All in One Printer always answers before you can use the external telephone, adjust the printer’s ring response setting.
Why will my Oki C5550 MFP not dial a telephone number?
If your Oki All in One Printer will not dial a telephone number, check the power cable and the wall outlet. Ensure the telephone line is connected to the LINE socket on the back of the machine, not to an external telephone or handset. If using an external telephone, check for a dial tone. If there's no dial tone, the telephone line may be faulty. If there is a dial tone, the printer might be using the wrong dialing method (pulse or tone) for your region. If you hear alternating tones instead of dialing pulses and your region uses pulse dialing, change the call parameters.
What to do if my Oki All in One Printer display shows a communications error?
If your Oki All in One Printer shows a communications error, try sending the fax again and ensure that you're dialing the correct telephone number. If an outside line prefix or international dialing code is required, insert a pause after the prefix or code using the Pause key to allow the machine to wait for a dial tone. If communication problems persist with a specific machine, program the number into a speed dial key and adjust its parameters.
