[LON-CAPA-users] Portable Exam Scanner

[Gerd Kortemeyer]

Hi Mark,

It takes the scanner about one second to read a sheet. Of course, the  
kids will pile up towards the end of a quiz. Don't know, 5 seconds per  
kid total ... if there aren't problems.

Potential problems:

* so far, the scanner did not create paper jam - I do not know how hard  
it will be to clear up a jam.
* in the absence of the additional LCD display, the scanner might  
reject a sheet, and the kid does not know why. The display (not tested  
yet) would say things like "OK" or "Question 3 missing," "Question 5  
double marking," etc

- Gerd.
