We can send faxes with no issues but when we receive a fax that has multiple pages after the first couple of pages we get half pages, partial prin or blank pages. We were told it was a possible system board issue so we replaced the Brother 4100e with a new one and are having the same issue. Has anyone ever heard of this. I am leaning toward a possible line issue but not positive. Any help would be appreciated.

Is it pulling two pages at once? Sometime a machine will start to pull a sheet normally, then the page below it will get dragged along by the friction between the two sheets. One page's print gets divided between the two. If that looks like the case, pull out the paper drawer, remove the paper, and lightly sand the little rubber or cork pad at the front, then wipe the dust off with a damp cloth and let it dry. Before putting the paper back in, grasp the stack at one end, and "fan" the other, allowing air to get between all the sheets.

Get into the machine's Paper menu to see what size is programmed for the tray. If you have Letter size in there, but it's set for some other size, all kinds of feeding problems can occur, including false jams.

The paper feed roller is controlled by a magnet lever inside the right side of the machine. It should click once to start each sheet feeding. I've seen one Fax 4100e that clicked over and over, feeding extra sheets, just like you described. It turned out to be the system board. Worse yet, Brother had switched factories in mid-production of this model, and the replacement board they sent us fed paper just fine, but wouldn't do anything right on the phone line. Couldn't dial, couldn't answer. They sent another replacement, and it was exactly the same. Brother eventually broke down and sent a replacement machine.
