Sounds like something is going on with your ADF. It should be looked at by a technician.

Remove the paper tray completely and make sure paper is not binding and lifting up OK.

I get calls all the time about fax issues. I work for Comcast and have guided people to the right answers about third party devices. We use a digital connection. Analog is a dying medium. Most calls are concerning HP and Brother but I know others fax machines have had problems too. The new HP machines have a digital setting. HP is aware of digital issues and can help you. It is unfortunate that old fax machines are not digital but a new fax is inexpensive if you wish to buy one. Analog takes up too much space. An example: Six digital television channels can fit in the same space (bandwidth) as one analog. That is why the FCC mandated the change. The same goes for phone lines. I Google almost every problem concerning fax machines and if you go past all the upset comments you will get to the comments that offer remedy. I also wanted everyone to know that a second, no frills fax line from Comcast is very inexpensive and our way of offering a dedicated fax line intead of a distinctive ring fax option.
