connecting my printer/fax to my modem/computer

[mtnpeeps]

I have Verizon DSL & a Canon multi purpose Fax/Printer/Scanner/Copier.  Everything was connected & functioning, when my phone line went dead.  Verizon sent a technician out who disconnected every phone in my phone & found it was the line to the printer. 

I've fixed it, but I can't get the fax to send.  I can receive, but not send.  I have the distinctive ring pattern & a separate number for the fax.  I know I'm doing something wrong, but I cannot figure it out when I trying to reinstall the phone line. 

I have a phone line from the wall to the splitter, in the splitter are the phone line & the line from the computer CPU.  Then the splitter goes to the modem.... 

Anyone have any suggestions?  What am I missing?  (I am so ticked off that the technician just disconnected everything because I have a million cords to my computer!)
