    SO many variables. Most commonly it is line failure. Or voltage drop. Are they receiving from other machines OK? The 4750e has a smart ring feature. Make sure it is turned off. Could be a LIU board that is failing. Check to see if they have not recently unplugged the phone line and possibly placed in the wrong plug. It should be in the Line plug.

When I send a document the receiver gets a large image. I want the receiver to get a letter size image. How do I do this?

The image would have to be resized before sending to less than 8.5x11 inches. You will have to open the image and click resize.

Fax will only send and not receive

Call your fax machine from a regular phone and listen for fax tones. Sender may be dialing the wrong number. Is your phone line DSL?

The majority of Brother machines will usually not recieve when they have a scanner error. So your lucky.

Under the top cover where the original goes you will see a glass strip (this scans your original). It should light up when the machine is powered on. If not this item has most likely failed. I have seen it before where rust around the contacts have caused it to not work and after cleaned the contacts it did work but usually it just fails.

Another way to checkif the machine will let you is to do a copy. If it comes out black it means the scanner has failed. It should be a relatively cheap repair if it has.

Sending and receiving faxes on legal size paper.

There should not be a problem with TX on LGL paper. If you want to configure the machine to recieve LGL on a regular basis: Press "MENU" 1-3. Then use the up/down arrows to select LGL. "MENU", "EXIT". That should do it. Good luck!
