Scanning from a File: Common Issues

This help document will address the basic requirements necessary to Process Images from a File as well as several common issues that can prevent this process from working.

Preparing to Process an Image from a File.

The Process Images from a File feature allows users to scan (using scanners) answer sheets onto their computer and process these answer sheets using GradeCam. This is an excellent option for districts and users who have access to a scanner but not to cameras or doc cams.

There are several basic requirements that need to be met in order for this feature to work correctly:

The only accepted file formats are JPEG, PNG, TIFF, and multi-page TIFF.

All files must be scanned in Grayscale and NOT Black and White.

The scanned images must be saved into their own folder; saving these images into a folder with word documents, excel files and other image files will result in an error and possibly prevent the system from processing the images.

All images must be 8.5"x11" (Letter size).

The resolution for each file must be between 150-300 DPI.

Important: Illuminate does not support any type of scanner or copier. Questions regarding scanner/copier related issues should be directed towards your tech department or district contact.

Is the file Black and White instead of Grayscale?

Is the file Black and White instead of Grayscale?

In order for GradeCam to be able to process an image, it must be saved in Grayscale. The left hand bubble is an example of a Grayscale file while the right hand bubble is an example of a Black and White. This can be ascertained by checking the settings of the scanner, zooming in on a bubble (as done above), or checking the properties of the file.

Note: Black and White images do not have the level of detail GradeCam needs to determine which answer a student selected.

Is the file saved in an accepted format?

Is the file saved in an accepted format?

The file must be saved in one of the accepted formats: JPEG, PNG, TIFF, and multi-page TIFF. PDF files and others will not work with this feature.

Is the sheet quality poor?

Is the sheet quality poor?

If the sheet has been scanned in poorly, resulting in distortion, faintness, or contrast issues, it is likely it won't be able to scan. Check all your answer sheets to make sure that they have scanned in cleanly and properly.

Is the file size legal size (8.5x14)?

GradeCam is not calibrated to work with legal size documents. Please change the size to the accepted format (Letter size, 8.5x11).

Is the answer sheet the problem?

Is the answer sheet the problem?

If the answer sheet has extraneous marks, poorly marked bubbles, disjointed or poorly printed black outline, or is missing key data (such as student ID), you may also encounter errors when processing from a file. As you would with a regular answer sheet, make sure that the answer sheet is within the basic requirements to scan.
