Some suggested tips for the microform reader/printer:
Blue screen of death – turn PC off and on again (and be sure fiche machine is turned ON before turning PC back on again).
Black/blank screen within scanning software – check autoexposure buttons on the fiche machine itself; then hit file/scan to page again to test.

Microfilm scanner
three selections to the scanning menu-
“Default”- 300dpi resolution 256 shades of gray scanning, with auto polarity and auto brightness selected. Best quality for printing, but 1MB per scan.
“Low Resolution”- 200dpi resolution black & white scanning, auto polarity and auto brightness. Good quality for text but bad for pictures. Good for PDF scanning.
“Darker”- Same settings as default, but darker prints.
“Legal Size”- This theoretically should scan a legal size page, but has not successfully printed a larger size. It could be that the software is capable, but the optical limitations of the scanner prohibit it. The printer is capable of it. We’ll play with it for a while and see.
Due to all of the strange dialog boxes that pop up, as well as the lack of options for selecting the modes above, I changed the lockdown of the computer. I gave the login full permissions to the machine, as an administrator, but installed DeepFreeze so that all changes would be reversed upon restarting the machine. If you have any problems with it, please turn off both the computer and the scanner, then start the scanner and then the computer. It seems to be hit or miss whether the scanner can be turned off and on without restarting the computer. Sometimes it works, other times you get the ‘blue screen of death’.
The scanner unit itself will enter a powersave mode after about 15 minutes, and the bulb will go off. It recovers well from this state, but students will likely turn the unit off manually since this has been the procedure with the older units.
