Fax recipt problems for Canon MF4150

I'm going out on a limb here, and guessing it's a Canon imageClass MF4150... If not, please disregard this solution.

The advanced manual can be viewed / downloaded / printed here, directly from Canon:

Look in the Advanced Guide for a possible solution on page 1-8 etc.

I am having a similar problem. You do have to connect your phone to the jack in the machine in the "Phone" jack slot, as well as have another line out to the jack in the wall in the "L" slot. That is all I know. I am having problems with my voicemail. Either I can received voicemail, and no faxes, or faxes, and no voicemail (fax picks up at specified number of rings). It is EXTREMELY frustrating. The machine is *supposed* to be able to discern between phone calls and faxes..and that is not happening.

Have you come across a solution? Aghhhhh!

I got in touch with the manufacturer tech support and found there was no way around it. Thanks for considering my issue though :)

How to Set the Receive Mode (MF4140/MF4150)
1. Press [Additional Functions]. 2. Use [Left cursor] or [Right cursor] to select [FAX SETTINGS], then press [OK]. 3. Use [Left cursor] or [Right cursor] to select [RX SETTINGS], then press [OK]. 4. Use [Left cursor] or [Right cursor] to select [RX MODE], then press [OK]. 5. Use [Left cursor] or [Right cursor] to select the receive mode, then press [OK]. [FaxOnly]: Answers all calls as faxes and disconnects voice calls. [AnsMode]: Receives faxes automatically and records voice messages. [NET SWITCH]: Distinguishes between fax and voice calls. [FaxTel]: Switches between fax and voice calls automatically. [MANUAL]: Does not answer any calls. You have to manually receive faxes. NOTE: a. For [FaxTel] or [MANUAL], make sure the optional handset or an external telephone is connected to the machine. b. For [AnsMode], make sure an answering machine is connected to the machine. c. The [NET SWITCH] mode is available for certain countries only and requires subscription to a network switch service. 6. Press [Stop/Reset] to return to the standby mode.

If you are using the phone while trying to send or receive a fax, it will not work.

There were some devices out that would allow you to do this, but they never really worked that well.

If you want to be on the phone, and send or receive a fax, you will need a second line for the fax machine, or you need to use a service like eFax (it sends a fiax like sending email)

on the settings, it needs to be set for a certain number of rings, and also on auto receive

Try changing the receive mode from automatic to FAX ONLY and set the number of fax rings higher. You should be able to receive phone calls and if you are not answering your phone it will automatically receive a fax.
