20 Most Recent Brother MFC 7840W Printer - Page 5 Questions & Answers


I had this same irritating issue - after uninstalling and re-installing several times I decided to check the folders to see if there was any remaining Brother folders or files hanging around. First I went to the Windows Twain32 folder and removed the remaining folder in there - then I went to Programs files (both of them in Windows 7) and moved all Brother Folders AND Control Center folders to a created folder on the desktop (just in case) - reinstalled the software and it worked! Hope this helps someone because I tried all the other fixes and they did not work for me.

Corona wire. Remove the toner cartridge with the drum. In the back of the drum you will se a green button on the right side. To clean it, slide it to the left and right several times and park on right hand side. Reinstall.

An IP address (Internet Protocol Address) is a logical address of a network adapter. The IP address is unique and identifies computers on a network. An IP address can be private, for use on a LAN, or
public, for use on the Internet or other WAN.

You cannot change the ip address, if you using static ip address.If it is dynamic ip address, you can change it easily by resetting the modem or switching it off and on.you can also use Proxy server or Hide ip address software to change the ip address.

To check the ip address before and after changing, you can visit the site Ip-details.com. Here you can search IP,domain host and it also includes city, country, global latitude & longitude coordinates etc.

Just put the scan job in the scanner and press the scan tab in your printer the scan image will appear in your directly connected machine/pc.

hello, i am going to ball park this, with machine on, open up front cover as if you are going to replace toner, press the clear button, on the display it may say, new drum press 1 for yes 2 for no, then close front cover. normally the drum comes with the instructions on this, but sometimes its missing, but also brothers web site has the info on this. i work on these alot so most of the resets are the same

Is any information given on the nature of the problem? In my experience the majority of problems with this printer is the correct prompt not being given to the printer when a new drum was installed. As such I would recommend trying the following:
-Open the front cover of the printer.
-Press Clear/Back.
-To confirm you have previously installed a new drum, press 1.
-Assuming the LCD now shows Accepted, close the front cover.

I hope this helps.

Here is the link from where you can download the driver, just filter the results by your operating system and then scroll down to the Printer Driver & Scanner Driver section: http://welcome.solutions.brother.com/bsc/public/us/us/en/dlf/download_top.html?reg=us&c=us&lang=en&prod=mfc7840w_all
