Printer doesnt come out of sleep mode (Brother MFC7420)

Hi there

i recently purchased a brother MFC7420 printer. The printer i connected directly to my PC and is set up perfectly as i can print, scan, fax etc etc. However, the minute i leave the printer idle for while it goes into sleep mode...then when i try and send another print job to doesnt wake up....i have to turn it off and on to get it to come out of sleep mode. Have asked brother ..they said to upgrade the firmware....which i tried to do but it says i have the latest firmware...

please advise...


No when I sent documents while my computer is awake to the MFC-8600 the THE MFC-8600 is a sleep, it will not print. I have to unplug the MFC-8600 and then plug it in to get it to print, my computer is awake all the time, the brother feature won’t allow you to keep it awake. It only allow to stay awake 99 minutes

SOURCE: "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.

1st check to see if there is a "dial tone"by picking up the handset. Then try to send a fax by using the handset.

I did not. The solution is a new scanner head which is almost as much as a new machine which I bought at Costco. I'm using my old machine for printing until it wears out, the new one for copying and faxing.

Receving large unwanted faxes

Please rate my solution. Hope this resolves the problem.

According to the manual one of the things that can cause this is if the data cable (USB) was disconnected from the printer while the job is printing. Press the Cancel button on the printer, that should clear the memory. Also make sure you don't have print jobs in the queue if the printer is connected to a pc.

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.
