The invalid timing marks error could be caused be several things.
First, check the template in the Template Editor to make sure the correct number of timing marks was entered in the template's properties by clicking File|Properties. If the number is correct compared to the form, check the form itself to be sure that the timing line is in the correct position.
Also try scanning several copies of the same form- do they all yield the error or just a few? If only some of the forms produce the error, it could be due to the way the form was printed. Ensure the forms are being properly placed in the scanner to avoid skewing. If all of the forms produce the error, the problem may be related to communications between the scanner and the system.
First try increasing the reader timeout setting under Tools|OMR Scanner. Doubling it is a good starting point. You can try several settings to see if there is improvement.
If the increased timeout does not resolve the issue, use the following checklist to ensure proper communications:
