Q1. Why doesn't Remark Office OMR recognize my Code 39 barcode correctly?

A. The Code 39 barcode specification mandates that a beginning asterisk (*) and ending character asterisk (*) are used as the first and last characters of barcode text. For example, if you wanted to format 1234 as a Code 39 barcode, you would type *1234* and then format it as Code 39. When Remark Office OMR recognizes this barcode, only the data is returned (i.e., 1234).

B. Space characters are not recognized in Code 39 barcode text. To use a space character, type an exclamation point (!). For example, if you wanted to format 
John Smith as a Code 39 barcode, you would type *John!Smith* and then format 
it as Code 39. When Remark Office OMR recognizes this barcode, only the data will be returned (i.e., John Smith).

C. Barcodes should be printed at a point size of at least 24 points (26 points or higher recommended). They should be scanned at a resolution of at least 200 DPI.

Note: The Remark Office OMR 5.5.1 update for version 5 contains a change that will read barcodes that do not have asterisks. Principia Products, Inc. implemented this change to assist customers that already have forms in circulation that were not generated with the asterisks. If you are using version 5, you can download the 5.5.1 update here.

Q2. Why do I receive so many recognition errors (Error #3100) when scanning my forms?

Remark Office OMR's recognition is extremely accurate when everything (from your form to your scanner) is configured correctly. However, errors in recognition can occur and are typically a result of poor form design or incorrect software / scanners settings. Some of the more common causes are outlined below:

A. For the best recognition, setup your templates on the same quality form that 
you will be reading. For example, if a template was created on an original printout and the user then tried to scan and recognize filled in photocopies, he/she runs 
the risk of recognition errors if the form changed significantly (lighter/darker, skewed, offset) when being copied. Along the same lines, use the same scanning resolution when creating the template and scanning the completed forms.

B. Good form spacing is an important element in attaining high accuracy ratings. 
You should use a minimum of 3/8 inch white space around a field of marks and a minimum of one character space between marks. Forms that have text, lines or graphics closer than 3/8 inch may encounter more recognition errors than well spaced forms. Forms which have marks which are touching (or almost touching) other marks, text, lines or graphics can expect a large number of recognition errors for those fields. The best solution for this problem would be to redesign your form to use better form spacing.

Note: Tolerances for form offset and skew decrease as form spacing decreases.

C. Although Remark Office OMR can recognize marks of almost any complete shape (circles, squares, triangles…), they cannot contain any gaps or breaks when scanned. If your form uses light, thin marks, (or if it is a poor quality photocopy) it is likely that when scanning the form, the marks will not be complete and Remark will not be able to locate them causing Error #3100 to occur. The best solution for this problem would be to redesign your form to use darker, thicker marks that do not break-up when scanned. Alternatively, you could adjust the brightness control to scan the page "darker" (e.g., -20) which would tend to make your marks more complete.

D. Remark Office OMR can adjust for page offset or skew for up to 3/8 of an inch for well laid out forms. If when photocopying the forms, they become offset or skewed by more than 3/8 inch, recognition errors may result. Correct for this problem by resetting the template to the photocopied form.

E. Remark Office OMR can adjust for page offset or skew for up to 3/8 of an inch for well laid out forms. If when scanning the forms your scanner skews or offsets the forms by more than 3/8 inch, recognition errors may result. Correct for this problem by adjusting your scanner's page guides or having the ADF repaired / serviced.

F. You must scan your filled in forms using the same scanner settings you used to create the template (e.g., page size, resolution and brightness settings). For example, if your template is set to a legal size page, but you are scanning forms using a letter size setting, recognition errors may occur. This problem can occur when using a TWAIN driver if you use the scanner in other software packages and change any one of these properties. When you scan forms again with your Remark Office OMR template, those settings may still be in effect. To resolve this problem, go to the Scanner Properties window (Tools|Options|Scanner) and select the checkbox for Show User Interface. When you scan, select the correct page size property, resolution and brightness in your scanner's user interface. Once these settings are correct and you have successfully scanned a page, you may go back to the Scanner Properties window and deselect the Show Scanner User Interface checkbox.

Q3. Can Remark recognize type written text (OCR) or hand writing (ICR)?

A. No. Remark Office OMR recognizes filled marks or check boxes (OMR) as well as barcodes, but does not include any optical character recognition (OCR) or handwriting recognition (ICR) abilities.

Q4. I am using the option to Automatically Detect the Presence of Handwriting for my Image field. Why isn't Remark Office OMR picking up all of my handwritten comments?

A. Sometimes if the handwriting is light or the image field is very large, Remark Office OMR will not pick up the handwriting. You can compensate for these problems by doing one of two things: 1) lower the Recognition Threshold for the individual field in the template (located in the Advanced section of the Properties window); 2) use the Recognition Threshold Override to globally lower the Recognition Threshold for all Image fields (located under Tools|Options|Read).

Q5. My form is double sided. When I try to read forms the Advanced option for Odds and Evens is not enabled. Why?

A. In order to use the Odds and Evens scanning function, your template must have an even number of pages. If you are using a form where the backside of the last page is blank, you must create a template page for that blank page. For example, if your form is 3 pages total, with the first page being front and back and the second page only having questions on one side, you will still need to create a fourth blank template page. When you are reading forms Remark will try to read the blank page, therefore it must correspond to a template page.

To create a blank template page, open the Template Editor, go to the last 
page of the survey and then insert a blank page. Do not create any fields on the page- simply save the template.

Q6. I would like each row of scanned data to have a sequential number indicating the questionnaire number that was scanned. Is there any way to do this?

A. Yes. You can create an Image field as the first field on your form. It does not matter where the image field appears on the form, as long as it is the first node. In the properties for the Image field, set the Field Type to Data. Set the Data Type to Numeric. Enter 1 in the Default Fill box and then mark the checkbox for Auto Increment. Click OK to save the field. When you scan with this template, the first form scanned will have a "1" in this image field. The Auto Increment option will then add a sequential number to each scanned grid row in the Image field.

Q7. When I scan my forms, the red OMR field that I created is jumping around the page, resulting in incorrect data or errors. How can I avoid this problem?

A. When this problem occurs, the fields are not actually moving. If a field is in the wrong position compared to what you see on the form, this is an indication that the scanned form does not match the template in some way. Remark Office OMR depends on consistency between the template image and the images of the scanned forms. If the fields are mispositioned, the problem is likely due to the same factors that can cause an Error #3100. Click here to see those factors.
