Remove your drum unit and you will see on top of where the drum unit sits inside your machine is a piece of glass(inside the machine). Wipe the glass with a soft dry cloth. If this do not work, remove your toner cartridge and see if the toner is spread evenly on the cartridge.

This could be a multitude of things. You would need to do some more "troubleshooting" style steps and post results here in order for someone to define an area of trouble. First, remove the "new" cartridge you put in and "re-insert" the old one. Did the problem go away? - Then you have a faulty "new" cartridge. - remember new cartridges can have problems too. After all we're only humans, and we can make mistakes. That includes manufacturers. ;)
If the problem still persists, TOTALLY unplug system from the wall. Wait at least 5 minutes and plug it back in. Turn it on, and tell me what you get. If the screen still comes up with new cartridge in place, then refer to above actions and scenario about replacing new cartridge if different result is achieved once older cartridge is returned and new result occurs.
Please ensure that "ALL" doors, handles, locking mechanisms, proper seating of cartridges, drum, fuser, etc is done. Re-seat each and every piece to ensure that ALL of them are properly secure and seated as they should be.
Report back with what you find and we'll go from there.. :)

I ran a search for the "Battery" in the service manual. It does not have a battery. The Time and Date clock function is control by an IC chip EEPROM on the main logic board.

Perform a Google search for the MFC 9700 service manual and the link will pop up,

There are several problems that could contribute to this issue.

the most likely would be the charge corona wire. it is located in the drum unit. If you can get to it to clean then do so. if not try replacing the drum. After that and the problem stil exists, Check the connection of the flat cable on the main PCB (Printed circuit board), then check or replace the main PCB. Or find an authorized service center.

This error means that there is a scanner motor error. Try and remove the error by following these steps: Press MENU *,2,8,6,4. The machine beeps for approximately 1 second and will display "MAINTENANCE" on the screen, indicating that it is placed in the initial stage of the maintenance mode, a mode in which the machine is ready to accept entry from the keys. Now you are inside the simulation, Press 01 to reset the error status. After that press 99 to exit the simulation.

- Pressing the 9 key twice in the initial stage of the maintenance mode makes the machine exit from the maintenance mode, restoring it to the standby state.
- Pressing the Stop button after entering only one digit restores the machine to the initial stage of the maintenance mode.

PULL OUT TONER CARTRIDGE SHAKE SIDE TO SIDE AND REINSTALL

did you reset the drum counter after replacing the new drum? Open the front cover and press the option button... then just select reset drum counter...and press set...

Try an old toner cartridge if you have one. Does it do it when you use the copier function. Steven 805-520-3003

Hello. Changing the baud rate and disabling the ECM can be done. I recommend that you go to the following link to speak directly with the MFC 9700 help desk at Brother. http://www.brother-usa.com/support/default.aspx?PGID=5&R3ModelID=MFC9700

This is something you can replace, its a consumable, the model number is DR-400, and can be purchased pretty much anywhere that sells brother products.

To see how to replace the drum please follow the link below.

the system keep on hanging

Error 77 basically means- Heater thermistor short circuit. However, the message is sometimes incorrectly shown. You can try this- power off the machine, take out the cartridge, close the door and power up. The machine should notice either the toner or the front door is not in place. Now open the door and place the toner. This might solve the problem. You can also try to soft reset the printer. If none of these works, you might have to change the thermistor.

You need to go to reports and print out something like the user settings list. If it looks bad as well, then your toner or drum is at fault. if only faxes and copies look bad then you need a new scan assembly.

i cannot scan & print my printer,show me how to download !

You need to make sure that your fax machine's ability to receive an incoming fax has been enabled. Please read your manual and follow the instructions to enable receipt of faxes.
