Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers. It would be my pleasure to assist you with this. In order to best help you, I'll need to ask a few questions.
I will need to know what operating system you have on your computer. If you're not sure, please click this link and tell me what you see:
Also, what is the model number of the 2nd Brother printer. Is that the one that you can't scan from?
Thank you for that information.
I also need to know what operating system you have on your computer. If you're not sure, please click this link and tell me what you see:
Thank you, ***** ***** that both should be fully compatible with Windows 7. Would you consider allowing me to connect remotely to your computer and work on this while you watch? I suspect that we may need to uninstall the software for the 9420, and reinstall it. It is also possible that the Brother ControlCenter software may need to be updated. If you'd prefer to do this yourself, please go to http://support.brother.com/g/b/productsearch.aspx?c=us&lang=en&content=dl, type in your model name (9420) and follow the prompts to locate the most recent version of the software for your printer and operating system. Be sure to choose the Full Driver and Software Package for your printer as this will also update the control panel to the latest version.
Is it now printing and scanning correctly? If so would you mind taking a moment to rate my service? I'd really appreciate it! Without a rating I am not credited for my answer. Thank you!
