Can not scan from mx4890dw buttons, only from the computer

Question

Hello,
I got this Canon AIO a few days ago. I followed the start up guide instructions, got it signed on to the wireless net work easily enough, and installed the software from the CD onto a Win 7 64 bit Dell laptop.
Printing worked perfectly from the get go. Also, "Copy" seems to be working fine. Fax appears to be working, although I can't confirm yet that a fax has gone through ( no one is at work ) and I may have some questions later about how to send and receive fax when sharing a phone jack with a Comcast modem/cable set up. And how to get it to accept faxs while ignoring voice calls.
As for Scan, after I figured out that I had to push the scan button and choose "remote scanner" ( I push the scan button/Remote scanner/ buttons, get the message "waiting" and then operate from the computer) the scan function worked perfectly, in single and duplex, when controlled FROM the computer and Canon MFC toolbox software. But for the life of me I can not get it to scan from the Canon mx4890dw buttons. I push Scan, then "computer", then I select my computer ( there is only one computer), then either color or BW scan. All seems OK until here. But after I select color or BW,  I get a screen that says :"Scanning" with the choice to either cancel or "confirm destination". I select Confirm destination, which then takes me to a screen which says: Confirm destination" showing both the name of my computer and "color scan". That is it, as far as I can go. If I press "OK" it just takes me back to a choice of confirm or cancel. I am trapped in a cycle between these last 2 screens. Once I get to the next to last screen that says "Scanning: cancel or confirm destination", the processing data light starts flashing green. After a minute or so it will stop flashing with the message "an error has occurred/CLOSE". Oh, BTW, I have registered the scanner on the Canon MF Network Scan Utility.
So, I figure there is some button I am failing to push, or I am missing a step. Any one have any ideas on how to get this to scan from the Canon machine?
Thanks
Bill

Thank you Deborah, but after many hours of trial and error, time spent with Norton 360 AV/Firewall folks, many install/uninstalls ( especially after I saw on the E-manual that if you plug a cable from the printer into the computer, and you want to go back to wireless, you must uninstall/reinstall the software), the problem is finally apparently completely solved.
I found what I thought might be the problem by accident. When I last got off the phone with Canon, all they had to suggest was that it was either a Norton or firewall issue, or possibly a computer issue, and nothing they could really do or suggest about that. I accepted this, but while wondering what in the world I was going to do, it dawned on me that my previous Kodak all in one( that this machine replaced) had worked fine, with no scanner problems at all, with this computer, Norton and network. So it seemed like it had to be something other than those things. And I believe a Canon inkjet all in one before the Kodak had also worked with no issues scan wise.
Then I decided to try something else on a whim: I cranked up my old Acer Win XP and installed the software, and guess what happened? Perfect function in all ways from the printer/scanner. Scanned perfectly from the Canon using the panel buttons on the printer. And over the wireless network on an old computer using the same Norton Firewall as my Dell. So it now seemed impossible that it could be the network or firewall. It had to be the only variable, the computer or someway the canon was in conflict with the Win 7 Dell. I bet you can see where this is going! So I go to the online support for Canon and sure enough there are Windows 7 drivers for download as well as a firmware update. So I down load these and clock on them, but as far asd I can tell, nothing happens. It appears they did not complete installation.
So the next day I am back on the phone with Canon. Asking in desperation if they can think of anything before I return this machine back to Staples and get something else, which I really hated to do, but I can't take any more of this, as now it had stopped printing also( but all still hunky dory on the Acer!). But this time, the person I am talking to quickly asks if I am trying to install wireless, and says "hold on while I get you to the wireless guys". The wireless expert listens to my problems and quickly says "did you download the Win 7X64 driver?". I said I had tried but it didn't seem to do much. So he has me download it again and shows me the trick: when you click on the download, it creates a folder somewhere else where the driver is actually stored. I click on that driver, and 10 minutes later all is working perfectly. In fact, before I even hang up with the wireless guy, I press the buttons on the Canon and scan quickly to the computer.
So for now all seems perfect, just as it was immediately once I tried it on the Windows XP machine. So I suggest that this be the first thing suggested when folks are having trouble installing on a Win 7 computer. In fact, I have since noticed there is a sheet of paper that came with the canon that advises downloading drivers for Mac computers. Too bad it didn't mention this for for Win 7 also, since apparently at least some of the installation CDs don't include these drivers.
Now I am wondering if I should try and do the firmware update? Kind of afraid to fix what ain't broke.
