Scanning the Test

Once the student answer sheets and the key sheet(s) have been filled in, you are ready to scan the sheets, score the test and print any results that you want.

Stacking the answer sheets.

Stack the sheets in this order:

key sheet(s)
optional letter grade key
student answer sheets/absent student sheets (optional)
optional result sheet(s)

Operating the scanner

If necessary move the MAXIMUM SHEET LEVEL guide for your forms - it needs to be in a different position depending on whether you are using the half or full sheet forms.
Depress the input tray lever (marked PRESS TO LOAD) and while keeping it depressed, place your forms in the input hopper tray (on the right hand side of the scanner). The black timing marks (which are located on the left hand edge of the scanning sheets) should be closest to you and the top of the sheet should go into the scanner first.
Release the input tray lever.
The scanner operator panel should display the message:

Press the Yes button.

See the WARNING at the end of this section if this message is NOT showing.

As each answer sheet passes through the scanner and the printer a number correct and percent correct will be generated and printed on each sheet. At the same time (if previously requested) incorrect responses, combined points earned, combined percent correct and letter grade will also be marked.
If you have included results sheets after the answer sheets these will be printed on next.
When you have finished scoring your test and any result sheets that you want have been processed, then you should press the Quit button on the scanner.

A message - Results will be lost - will appear in the window and if you really want to quit press the Yes button. The scanner will now be ready to score another test.

WARNING: If

is showing in the display when you are ready to score a new test, then the key to a previous test is still in the scanner's memory, and your test (including your key) will be scored with the previous key if you press the Start button. This may not be obvious to you at first if you have the same number of questions as the previous test. If you suspect something like this has happened, check the roster number printed on the first answer sheet - it should be 1.

You need to clear the previous key before you put your key in. To do this, press the Quit button and answer Yes to 'Results will be lost Quit?'You should now see the message 'Perform Test Scoring' and it is ready to score a new test.
