Top 20 Brother MFC 9700 All-In-One Laser Printer Questions & Answers

To get the service manual for your MFC-9700 (see page 7), go here: https://www.manualslib.com/manual/456614/Brother-Mfc9700.html#manual WD-40 works the best, as most parts would not be damaged by it. Try to figure out by looking at it when it is printing what parts are rotating (this may or may not require some disassembly). If you decide to spray something that rotates (like the hubs of the little rubber wheels that move the paper), be careful to use it sparingly and don't spray it all over everything. A spray of 1/100 of a second or less will usually do the job. Good luck.

Depending on the machine it may require the scanner light to stay on to minimise warm up time when using the scanner.

Press the Ink button -> Test Print -> then choose Print Quality -> the printer will then go through and print a series of small squares in each of the four colors in the shape of parallelograms. If you see any gaps in parallelograms then you will be asked asked to clean the cartridge, do so. -> Just keep repeating process until there are no gaps Then I did an Alignment check right after the cleaning through pretty much same process: Press Ink button-> Test Print -> then choose Alignment-> and make sure the patterns match to the closest number In Case You Still face Problem and Need Online Assistance Then Please Follow Us For On : Brother Printer Support

Brother MFC's usually come with some version of the ScanSoft software. One of it application is called pageviewer. View the fax through page viewer.Besides, if you faxed from the computer, the original file must be on the computer. Launch a search for it.

Hi, maibe it is the cartidge, the pinions not working. Pull out the toner cartridge and replace with another, if you have. If not you must try to rotate the cilinder and see if work.

REINSTALL THE DRIVER OF SCANNER

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.

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.

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

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.
