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 MFCGoodluck! If you still need more assistance. Call us 1-877-Brother. :)
What does error code 20 mean, when faxing?
First...do you have or previously other printers on your system or network.You need to make sure that the system recognizes this printer as the default printer.If it was me...I would reinstall all of the software to eliminate any issues and make to make this your default printer....If you are running windows Xp..once you reinstall the software....go to the start button....the my computer...control panel....printers and faxes..this should show all printers in the system...if your printer has a check mark beside it...this the default..if if is not checked...right click on the printer and make it the default.You should not get the error message again...I hope this was helpful.....
Brother mfc-7840w won't receive fax
The first thing that I would try multiple people to ask them to fax you.Sometimes the 2 machines don't "sync".This is a toll free fax test number that I always use to check my machines..1-888-473-2963.Just write the words "FAX TEST" in large letters on a blank sheet of paper..fax it to that number...leave the line open...you should get a fax back in about a minute.If you get a fax back...your machine is fine...let me know if this was helpful....thanks.
Keeps saying drum to end soon.
You need to open the front cover ( where the drum and toner is installed), then press the clear/back button, then will ask if you replaced the drum, chose one for yes, it will says accepted, then close the cover.
How do I enter the number
Brother's documentation is non-intuitive. Pressing the ' 0 ' key shows a ' * ', but it actually is accepted as a 0 and moves to the next character entry position. Just take it on faith that it enters a 0 when it shows * when entering the wireless key.
I want to print with the black ink jet only, how
You'll need to go into your printer preference and set the options you require.
In this case, once in printer preferences, you should see a "Greyscale" box, check said box. Printouts will then use just the black ink.
Start - Control panel - Printers - Preferences.
