HOW TO READ EXAM ANSWER SHEETS
Our opscan reader scans exam answer sheets at a rate of 25 sheets per minute.
It is located in Room 383. When you go to this room, BE SURE TO BRING A
PENCIL WITH AN ERASER.
The Sun workstation in Room 383 should be displaying a login window.
But instead of entering your userid, click the button marked "Options"
which will open a submenu. Click on "Command Line Login." A window
will open, and you should press the "Return" button on the keyboard,
which will enable you to log into your Sun account.
Once you have logged into your Sun account, cd to the directory in which you
wish to write the output file from the opscan reader.
NEVER TURN OFF THE POWER TO THE WORKSTATION.
There are two gray buttons: press the one on the left to turn the power on.
Put exam sheets in the tray and press the lever marked "Press to load".
The sheets should be oriented so that the black timing marks are towards the
front of the machine.
Type "gread" to start the program to read answer sheets. (But instead type
"greadf" if you are using answer sheets that allow numerical answers). The
program will prompt you for a file name; type something like: exam1.ms
When the prompt "?>" is displayed, press the right gray button on the
reader, which will cause one sheet to be read.
Type "c" followed by carriage return, and the remaining sheets will read in.
(If your exam allows multiple answers to a question, type "m" instead of "c").
The machine will stop if it detects a mistake, most commonly when a student
fills two circles on a single column in the identification field. Take out
the flawed sheet, fix the error by using the pencil and eraser, put
the sheet back the input tray, and type "c" to continue.
When the program first detects a missing name or missing exam code, it will
announce the anomaly and offer three options. I recommend that you enter "c"
which will reject the sheet and continue scanning. You would then remove the
sheet, fix it if possible, and read it in again.
After all sheets have read in, WAIT for the prompt, then type "s" to close
the file and exit the program.
Type "exit" to log out of your account.
