Setting the number of rings

For more details on how to setup your Lexmark X4650 printer for faxing, please refer to the User's Guide found on the Lexmark website.
Additional info:If you have an answering on the same line as your fax:

To make sure the printer picks up incoming faxes, set Auto Answer to On, and then set the printer to pick up after a greater number of rings than the answering machine. For example, if the answering machine picks up calls after four rings, then set the printer to pick up after six rings. This way, the answering machine picks up calls first and your voice calls are received. If the call is a fax, then the printer detects the fax signal on the line and takes over the call.

If you have a voicemail feature associated in the same line as your fax:

Voice mail and fax can share the same telephone line if you subscribe to a distinctive ring service offered by your telephone company. This feature allows you to have multiple telephone numbers on one telephone line. Each telephone number has a designated ring pattern (single ring, double ring, triple ring, or double and triple ring). The different ring patterns let you know which telephone number was dialed, and which device you should use to answer the call.

If you do not have distinctive ring service, then set the printer to receive faxes manually (Auto Answer Off). This setting lets you receive both voice calls and fax calls, but works best if you use voice mail more often. You need to turn off voice mail whenever you are expecting a fax.

I hope this helps.

Should you need further assistance, please contact Lexmark Technical Support Center.

It seems that you're sharing your home phone line with your Lexmark fax machine. You can adjust the "pick-up" ring from the printer operator panel by pressing the Setup button > Fax Setup > Ringing and Answering > Pick Up On > select your preferred number of rings before the fax answers.
Please note:
If you have an answering machine connected to the same line as the fax, set the answering machine to answer incoming calls before the printer does. Increase the number of rings by a factor of 3 over the answering machine. For example, if the answering machine is set to pick up on 4 rings, set the printer to pick up on 7 rings.

If you have a voicemail feature in the same line as the fax, you may subscribe from your phone service provider for a distinctive ring pattern feature. You can program your printer to have a distinctive ring pattern and phone number for incoming faxes.

Either your fax machine is set to answer on more rings then your answering machine is or you dont have the automatic answer key pushed?

Determine how many rings your answering machine picks up on and then change the number of rings to a lower amount on your fax machine. To change the number of rings before picking up the line, press the "menu" key on the fax machine and use the up and down arrows to scroll until you find the "basic fax set up" or the "advanced set up" areas. I am not sure which one will have the number of rings setting. Try looking in both until you find it.

when you see it press "ok" or "enter" get in and change the amount of rings before answering. call your fax machine to make sure it picks up before your answering machine.

This should solve your problem.

Set rings to answer
You can select the number of rings that will occur before the fax answers an incoming call. If you are using your machine as both a telephone and a fax machine, we suggest you set the ring count to at least 4 to give you time to answer.
TIP: HP 1050 Fax: The Toll Saver function for the Digital Message Center interacts with Rings to Answer. See Toll Saver on page 40. If you have the HP 1050 Fax and have Toll Saver turned on, set the Rings to Answer to 2.
1. Press Menu repeatedly until BASIC FAX displays and press Start/Enter.
Rings to Answer will display.
2. Press Start/Enter.
3. Enter the number of rings you want (2-7) and press Start/Enter.
The HP Fax rings the set number of times and then answers. It then produces a different sounding ring to alert you to which type of call is incoming.
• The additional ring may occur once for a fax call
• The additional ring occurs 5 times for a voice call. After the 5 additional rings, the answering machine will answer.

>first run fax test, press set up go to tools menu then select run fax test,all entries should be pass
>then check your connections, do you have one line or number for your fax and phone?or a separate line or another number for fax and another number for phone?
>let me assume you only have one number for fax and phone..
>check connections, this should be downstream connection, the fax machine using the black phone cord provided by hp should be connected directly to the phone jack using line 1 at the back of the fax and the answering machine or the telephone should be connected to ext 2 or line 2 at the back of the fax...there should be no other devices phone or answering machine connected directly to the phone jack.
>next set rings to answer on the fax machine higher than the answering machine...if your rings to answer on answering machine is 4 rings, set the fax to 6 rings...if it is a voice call the answering machine will pick it up at 4 rings then if it detects that it it a fax tone then it will transfer the call to fax.
>also check if auto answer is on in your fax
>you can check auto answer and rings to answer by pressing set up or menu button on your machine look for it in basic fax settings or advance settings
>also check if your voice prompt for your answering machine is not too short there should be like at least 5 seconds after cutting your message to allow the machine to transfer the call to the fax if it is a fax tone.

I have a HP Officejet J6480 All-In-One and needed the answering machine and fax to be on at the same time.  I called the help line at HP and they said I needed another phone line into the home but I tried this and it worked. 
First I got a different phone number for the fax machine - they do this for no charge at my phone company. This is not another physical line into the home - it is just another phone number with a different ring - it rings 2 fast rings for the fax machine instead of the phones regular one ring. I set the answering machine built into the phone to pick up after 4 rings and I set the fax machine to pick up on 2 rings. Be sure to set it so the fax pick up number of rings are less than the answering machine pick up number of rings.  It worked for me. Hope this works for you too.

Hi,

Setting Ring Delay:
The Ring Delay setting determines the number of times the fax machine rings before it answers. If you have extension phones on the same line as the fax machine, keep the Ring Delay at a default setting of 4:
1 Press Function/Set, 2, 1.
2 Press < or > to select how many times the line rings before the fax machine answers (00 – 04) and press Function/Set. If you select 00, the line doesn’t ring at all.
3 Press Stop to exit.

Hope that's clear enough :)
