FO2080-Please give input regarding fax connectionon this multi-function machine

[axyun]

Normally I would just put this under fax machines but this
machine is really a Sharp AL series type machine with faxing added. Most parts are interchangeable.
Machine is an office in hospital doing about 2k per month between faxes and copies. The machine was set up Sept 2. It was moved to adjoining office a month ago and on Jan 7 machine had an E1-00 error code. Fax board was blown. I replace board with new one and okay for now. While waiting for board i gave customer a Sharp AL-1661CS as a loaner. The next day customer called and said they could receive but not send and machine would not respond to numbers attempted to be entered. They said they would wait until Fo2080 was returned as they did not send much but primarily received.
When I returned Fo-2080 I noticed that the Al-1661cs was plugged into a splitter that plugged into wall jack. A phone from anothe dest was plugged into other side of splitter. The phone unit has 3 lines that jump when one is busy. This did not seem like an appropriate hookup and I explained my concern to one of the staff and said I thought they should have a dedicated line for faxing. I was told other machines they had were hooked up same way without a problem. I had 2 machines plugged into that splitter and a problem on each machine so I am wary.
When I returned to my office with the loaner I immediately plugged it in and hooked up the fax. I got a dial tone and the machine responded to numbers entered. I did not get dial tone at hospital and of course you could not enter numbers. For some reason I guess the FO2080 works in that environment but I am afraid that maybe that type of hookup may have been responsible for the fax board blowing.
I know this is a long story but I wanted you to have all the facts so you could make a comment of what you think of this situation. Your response is very much appreciated as I am hardly an expert no fax connections. I just try to fix the machines. Frank/ActionPhotocopy

You tell me if this is pertinent:

I had a call on Jaguar series machine which would not send or receive, and no dial tone when Hook was pressed. Usually powering Off, unplug, and wait 10 minutes would reset it. After three of these events the fax portion of the board would blow and I'd have to replace the MCU.

In the end we determined that you can't run an MFP off a ground-fault outlet. I don't know the reasoning, but once the receptacle was changed to an ordinary outlet the problem ceased. =^..^=

We use the ESP surge protectors. They have ports for the power cord, network and fax cables. These are charged to the customer at install and give us a little piece of mind as techs. The surge protectors do not work on GFI either. As for faxing in the digital age; it can be tough. A DSL line will have a splitter, one side for the phone, and a filtered side for the fax. If you plug it in without the splitter, it makes some interesting noises. I have one customer that has 2 MFPs used to only receive faxes utilizing 4 rollover lines. VOIP phone lines and analog fax kits don't always play nice. I always tell the customer no voice mail, credit card machines, even call waiting can cause problems. If they are insistent about not changing, set the fax ring detect to 1. It will grab the line before anything else has a chance.

Why do they need to use a splitter? Why not just use the extention port on the machine. Good luck
