How do i send a fax?


Hi kimberley299,

To send fax using your Canon Pixma MX340 follow the steps below:

1. First, you need to hook up a phone line from the wall jack to the lower phone jack on the back of the PIXMA.

2. Now go into the menu and set your PIXMA to telephone priority mode (manual fax recieve), fax priority mode (auto fax receive) or distinctive (fax) ring/auto answer mode.

3. To send faxes, put your originals in the feeder or on the glass, select fax mode, enter the phone number, and press start.

Hope this helps.

Thank you for using FixYa.

CANON PIXMA MP 780 WILL NOT PRINT FAX. ALL INK CART. HAVE BEEN CHANGED. HELP!


Do you have a dedicated telephone line or is it a shared line with answering machine or telephone? Were you able to receive and print faxes at one time or have you never been able to print a fax? Are there any error messages or error lights?

If you are not getting error codes it sounds like a basic set-up and configuration problem. Make sure the telephone line is connected properly

See here. Also suggest referring to pages 35 and 43 of the Quick Start Guide

You may also want to check to see if you have the most current driver for your operating system. drivers and software are available here.

Without much more detail simply can't provide more specific assistance.

Cannot receive faxes on Canon Pixma MX870, but can send faxes


I was searching for an answer to this to make sure my new MX870 is correctly set to receive faxes. Here's one answer I came across:

First set Tel-Priority, turn off incoming ring, turn on manual/auto switch, then check how many seconds it takes for your answering machine to come on, and set it a couple of seconds after that. This should do the trick.

Trying to fax with pixma mx7600. Plugged phone


You probably want to plug the phone line (the line from the wall) into the port marked "L" for line on the back of the Fax machine. The jack with the picture of the telephone handset is for your optional voice phone to share the same line with the fax machine.

I have a PIXMA MX850 printer. The system was preset to fax priority mode so I had to keep the printer off to use my phone line which is 99% voice and 1% fax. I have now configured the printer to TEL...


It will only automatically pick up the line when set to "fax". You need to subscribe to a "distinctive" ring (which is a double ring) service through your telephone company and set the rings to answer appropriately so as to not conflict with your voicemail

How do you set up fax phone on the HP officejet 6215


hi you really have a very good choice of printers is one of the best printers from hp
inorder to set fax on ur printer you should first be sure what type of telephone line you are using
there are 2 type of line 1 dedicated -> that is directly attached for fax and has no other telephone or TAM connected if you have this line you can directly attach the phone line on the printer line 1
the other type of line is shared that means you use the same line for phone and fax in this the connection should be as :- telephone line from wall jack to the printer line 1 then from printer ext port to telephone answering machine (if any ) then from answering machine to telephone (if u have a dsl line that means u use phone and internet from the telephone line then there will be 2 lines comming out of the splitter 1 to router and other to telephone here follow the shared line connection mentioned above using the line that goes to the telephone )
now power on the printer and press the setup button (menu) now navigate to basic fax set up press ok and then go to rings to answer it should be 4 rings now go back and go to advance fax setting and then to distintive ring (DRP) select all rings and press ok now run fax test if it passes then ur fax is set up try sending fax now hope this will help you

PIXMA MP780 will not receive fax with Verizon DSL connection. Before unit was ok with comcast cable, Note: I'm able to send fax. RBRANT


Solution: Contact local phone company to check the telephone wall jack for low ring voltage.

Ring-in Voltage Facsimile equipment?(fax machines), like other telephone anwering devices, require ring voltage at a telephone jack to answer automatically.? The ring voltage is one of the services provided by the local phone company.
  • Low ring-in voltage can cause short bursts of ring tones at the phone jack.
  • Callers may hear one or two ring back tones and then ringing will stop and nothing else will be heard.
  • Inside the home, the called party will hear a brief ring and then nothing else will be heard. If the telephone handset is lifted, the caller may be on the other end.
To check if the fax will not answer due to low ring-in voltage, do the following:
  1. Disconnect the fax at the telephone wall jack.

  2. If an answering machine is available, connect it directly to the telephone jack. If an answering machine is not available, connect a telephone to the telephone jack.

  3. Dial the fax line and see if the answering machine answers the call, listen for uncommon ring tones inside the home or check for similar symptoms as described above. If any of the above symptoms occur, please contact your local telephone company.

Getting to answer phone before fax or message bank cuts in


to stop the pixma from picking up even after the phone line has been picked up you need to ensure the telephone line is connected to the LINE port and not to the PHONE port on the back... the PHONE socket is if you wish to connect a phone line to the same socket Thru the pixma. (passthrough)

not sure how to stop the pixma picking up on the first ring though..... are you sure that you are SAVING the setting change.....?

MX310 fax problem


We have the telephone and printer/fax on the same line and, when the printer is turned on, the fax rings when receiving a phone call. The incoming phone line is connected to the "telephone" modular jack.
