How do I get out of download mode?

Try power it down, unplug it, wait at least 30s and reconnect it.

If that doesn't work, try resetting the device by: powering it down, click and hold the [Reset] button, and whilst holding it, turn the power back on. Keep holding the [Reset] button until the main screen reappears...

When still no luck, try contacting Canon support directly:

Good Luck !

After a power outage, the lid is locked and won't open. I tried running a new cycle but won't run either. Any suggestions. Thanks, Jan

This is a common problem, often associated with a momentary power failure when the controller doesn't get time to reset and return to an idle state before the machine gets power back and it gets "confused". Regardless of the cause, you will almost certainly find that unplugging from the mains (Not just powering off on the button, as some door locks have a sneak circuit, even when the power is turned off at the button) and leaving the machine undisturbed for a full 20 minutes will allow a reset, the door lock will disengage and all will be well when you power back up.
Additionally, on older machines with analog program selectors, turn the selector to an end of program setting before you power it off.

Receiving E,2,7 Error messages. Can't clear. help please!

Canon support says reset machine by holding power button for one second until the display shuts off. Wait ten seconds, press power button - allow machine to completely turn back on. Otherwise, they say your printer may need repair.

(If holding the power button will not turn device off, you may unplug the power cord as an option).

Can't install Canon ImageCLASS D780? Please help

I just checked on the Canon USA site here, and selected Wndows XP as the OS. The driver presented shows Windows Vista in the file name (D700_PrtDriverV110_WinVista_EN.exe), but the next screen shows that it is compatible with Windows 2000, Windows XP, and Windows Vista. I would try uninstalling (if it is installed) whatever driver you currently have installed for your D780, then download and install this driver. Leave the unit turned off until the installation program asks you to connect/turn it on.

System froze - can not print or set to fax

Does anything at all appear on the control panel?  Is it possible that it tried to print the report and then jammed?  Does it give you the normal beeping error sound at all or just not respond to buttons?

Are you able to do press the number of copies or any other buttons working?
