''Back door open, please close back door'' - back door is closed

Hi my Brother fax machine MFC 7420 keeps saying that the back door is open when it is not - its fully closed. I've turned the fax on and off and and plugged it out but still to no avail

    After clearing a paper jam with power off, the error message "Back Door Open" appeared on the LCD when powered back on. Back door is securely closed, I've repeatedly inspected for any loose bits of paper, but the problem does not go away. I've tried opening-reclosing the back door, then pulling power plug for 30 seconds -- that does not clear up the problem either.

    I have the same problem and opening, closing, and unplugging does not work. How do I force this machine to perform full self diagnostics?

HOW DO I un-lock the scanner on a Brother MFC 7420?


Unfortunately, the MFC-7420 doesn't have a physical lock switch. You need to turn off the all-in-one and wait for the unit to clear its memory. If the error recurs after you press the power button again, wait 30 minutes and try again. (Note: you will lose any faxes that are in memory. See the User Guide page 11-5 to save this information.) You can find the manual on the Brother support page for the MFC-7420: https://www.brother-usa.com/support/ModelInfo.aspx?R3ModelID=MFC7420 . Click on the Manuals & Documents tab. Then click on the Manuals on our Online Solution Center for the English version of the manual. The direct link to the User Guide is currently: http://download.brother.com/welcome/doc000387/ALLFB_UsaEngUsr_B.pdf .

You can also try unplugging the all-in-one for several minutes to reset the error codes. If the error persists, contact Brother if the MFC-7420 is still under warranty (1 year). If it isn't under warranty, consider replacing the unit. The repair costs may be unreasonable.

I hope this helps.

Prinnter not printing but showing 'put custom in manual tray'


There is still a print job in the queue. Place a sheet so it prints or kill the job.


Open Printers and Faxes. Open printer. Highlight jobs and Right click > Cancel, or Documents > Cancel.
For those stubborn jobs, Right click My Computer > Manage. Choose Services and Applications > Services > Print Spooler. Right click and stop. Then start. This may have to be done from the Print Server if it's network printer. Contact IT to kill.

My fax wont work in my ricoh aficio 1515 mf??


Using the 1515 as a fax machine is a pretty simple procedure if everything works right. All you have to do is hook a working phone line up to the phone jack on the back of the copier (the one labeled LINE, not TEL).

Why won't the fax work? If it is giving you an error message, what is the message?

If you are not getting a dial tone when faxing, unplug the fax from the phone line and plug a working phone in, and see if the phone gets a dial tone. If it doesn't, there is a problem with your phone line.

You can also try plugging the fax machine into another phone line. If the fax works on that line, then there may be a problem with the first line.

Are you having problems sending faxes or receiving them, or both?
