    The problem started first thing this morning. The phone rings, the window shows that it is receiving then suddenly it goes to Sleep Mode. Twice the message "Call Back" came up, went to Receiving, then into Sleep Mode. Any suggestions? Also I am having trouble getting hold of an Owners Manual.

1. Machine is on telephone line shared with a 3 handset cordless Uniden system so telephone may be answered around the house. The machine no longer rings when calls come in so we only here the Uniden...

These machines come with several receiving modes that can be programmed ... mostly by design but quite often ... by accident.

I would check the User Manual for Ring Patterns, Silent Reception and Fax Priority.
You can always see or print out the Option Settings of your facsimile. There it will show the exact picture of what the fax must know before answering the incoming call.
Does it have Fax Tone Detection? Is it set for automatic answering? Faxback? Polling?

Maybe a power hickup might have scrambled some of the programmed features?
Obviously nobody in the location monkeyed around with tha fax buttons, right?
By George. Of course not!

Please feel free to contact me anytime.

Lcd says sleep 10: 35 fax. What does that mean?

The machine goes into the sleep mode after the amount of time you set to conserve energy. It is sleeping and will wake if a fax comes in, fax tells you it is in the fax mode and not the manual mode or fax/tel mode. 10:35 is the time of day.

I can send but cannot recievefax. Fax is on SLEEP all the time.

The machine is set with the sleep mode as a default. The fax part can be changed to recieve a fax by pressing the fax mode button. Press it until it says Fax only, not F/T. F/T means Fax/Telephone. This mode would make it to where you have to pick up the reciever and press start when a fax comes in. The Fax only mode means it will pick up everytime a fax comes in automatically. Let me know if this was helpful. Please give my helping a rating. Thanks!

Your Brother machine#s Sleep Mode function reduces power consumption while the machine is idle. You can adjust how long your Brother machine is idle (between 00 and 99 minutes) before Sleep Mode is initiated. Please note that the default setting is 00 minutes, and the timer automatically resets itself after the Brother machine receives a fax,receives data from your PC, or makes a copy. To adjust your Brother machine#s Sleep Mode setting, please follow these steps:

1. Press MENU/SET, 1 (General Setup), 7 (Sleep Mode).

2. Use the dial pad to enter the amount of time the fax machine is idle before Sleep Mode is initiated (00 to 99 minutes).

3. Press the MENU/SET key to confirm your choice.

4. Press the STOP/EXIT key to exit the menu.

NOTE: If you frequently print, copy, or fax, set the idle time long
enough to insure that you will not always have to wait for the Brother machine to warm up.

"Receiving Sleep" on Brother Fax 4100

The sleep mode is only a power save mode. You may not have the machine in the correct fax receive mode. If the machine is on a line by itself it needs to be set to fax only, if line is shared with a telephone it needs to be in fax/telephone, if you share the machine with an answering machine it needs to be in TAD mode, and so forth. Each time you press the MODE key it will change the receive mode. Most people hit this key by mistake and change the MODE and the unit will not pick up calls. Press the MODE key until you are in the correct mode. To make sure the machine will print, press reports and then the 1, this will print a help list. If the help list prints you know that the machine works. Then check to make sure the machine is in the correct fax receive mode.
