Make sure that your Gel Doc camera is turned on. If the camera is not turned 
on, the Gel Doc acquisition window will open but the screen will be black, 
and you will be unable to Video Print.
Simulation Mode
Any of the imaging device acquisition windows can be opened in “simulation 
mode.” In this mode, an acquisition window will open and the controls will 
appear active, but instead of capturing real images, the window will create 
“dummy” images of manufactured data.
You do not need to be connected to an imaging device to open a simulated 
acquisition window. This is useful for demonstration purposes or practice 
scans.
To enter simulation mode, hold down the CTRL key and select the name of the 
device from the File menu. The title of the acquisition window will indicate 
that it is simulated.
3.1 Gel Doc Acquisition Window
To acquire images using the Gel Doc, go to the File menu and select Gel Doc....

panel and a video display window.
