How to extend the life of a TN-330 drum kit for MFC-7840W Wireless Printer


If you have received any of the following messages on your Brother MFC-7840W wireless multifunction printer while utilizing the TN-330 drum kit then you may not have to replace your drum, at least not yet.

Drum End Soon
Drum Error
Toner Life End
Toner Low

I had this issue happen to me about 150 pages ago (some text, some pictures) and I still haven't replaced my drum after I executed this little trick.

Take your drum kit out of your printer (make sure you turn off and unplug any cables first)

Take some black electrical tape and cut a inch by inch square off.

Place the black tape over the optical port as shown in the picture below.

Then put the drum back into the printer, cable everything back up and turn the power on.

Your drum should last a long time beyond what was supposed to be a low toner.

Hopes this saves you some money.

Brother mfc-7840W not picking up wireless IP address


It is common, mainly because the MFC connection is lost to your PC. Are you able to print or scan from another wireless PC that you have? If yes, contact your network admin or router oem. If no, reset network card. Run the Setup Wireless Wizard. Make sure you have router info such as SSID, Network Security Key, Authentication Method (Open, Shared, WPA/WPA2-PSK), Encryption (None, WEP, AES, TKIP). Enter those info, it must be CASE SENSITIVE. Just in case you dont know your router info, contact your router oem.
For Advanced Users.1. Click your Wireless Icon at Task Tray2. Right-Click your Wireless Network Name3. Select Properties4. Go to Wireless Security Settings5. Take note of the settings that you have there and enter it again on your MFC
Goodluck! If you still need more assistance. Call us 1-877-Brother. :)

MFC-7840W Printer: need tp set the wireless setting, lost the instruc...


To setup your Brother MFC-7840W on a wireless network do the following:

Press Menu.

Scroll down to #5 LAN and hit OK

In the LAN submenu, scroll down to 2. WLAN and hit OK.

In the WLAN submenu select 2. Setup Wizard.
(The printer will search for the SSID of your network. If you are presented with multiple networks, select yours and hit OK.)

Depending whether you have setup a network key on your wireless network, you will have to choose the type of connection. Your options will be Open System, Shared key, and WPA/WPA2-PSK.

If you have a Shared Key or WPA/WPA2-PSK network, then you willhave to enter the key to connect. Open Key does not use a key to connect.

So for instance, if you selected WPA2-PSK you will then be asked to enter your passphrase key to connect to your wireless network.

Brother MFC-7840W Printerwill only give me Scan To FTP option now


i had the same issue - was previously able to scan to a number of different formats, then switched modems, providers and then only the scan to ftp option came up.
took me about an hour to figure out the solution, but now it works
for windows users: * go to your control panel * go to the scanners & cameras section * your printer/scanner should show up here * right click on it and select 'properties' * select the network settings tab and then -- enter in the correct ip address here OR -- specify your machine by name (enter in name here)
hope this helps!

Networking


It isn't a network printer since it only has a USB interface (no LAN port)
http://www.brother-usa.com/VirData/Content/MFC/ModelBrochures/Brochure_MFC240C.pdf

but you may purchase a print server if you want to share the printing function on your network (only the printing function can be shared). But some multifunction printers do not work with print servers due to driver issues. There are some users on the net who were able to make this work with an IOGEAR multifunction print server.

There is one Brother multifunction network printer that you may want to check:
