The error message "The dimensions of xyz do not match the expected size" while scanning or loading targets can be caused for a number of reasons. Depending on the style of shooting, Orion does an initial dimension check on each target images, making sure the target image reasonably has the correct width and height. If for some reason the image does not, Orion displays this error message. The cause can be one of the following:
Using non-supported targets may cause this error. Only targets with the words "Target designed for use with the Orion Scoring System" should be used with Orion, and in some cases targets approved by the ISSF. To learn more visit our FAQ page on this subject.
Settings within the scanner driver play an important role in how targets are scanned in for processing by Orion. In general the scanner should be set with:
•24 bit color
•Match original page size
•Saved to loss-less JPEG images
•Scan only in Simplex mode

The Canon DR M-260 scanner drivers have a bug in them that will mis-interpret the size of a scanned document and erroneously set the size to it's maximum possible. If you are scanning with the M-260 and you receive the error "the dimensions of ... do not match the expected size" this Canon bug is very likely the culprit.
Shooter's Tech is working with and encouraging Canon to fix this bug. Until then, there is an easy work around.
For complete walk through visit our help page DR M-260 Bug Scanning with Match Original Size.
In general the walk through involves the scanner drivers setting page size from Match original size" to the actual size of the targets you are scanning.
If the scanner feeds two targets, the resulting image may be out of proportion with the standard target size and Orion will not recognize the image as a target. This is one of the few cases where it is appropriate and correct to re-scan the targets.
To correct this error, rescan the misread targets.
If this occurs frequently you made need to consult this section regarding doublefeeds
•With the DR-M160II, DR-C240, DR-3010C and P-208: targets are loaded such that the top of the targets are feed into the scanner first. The aiming bulls should face away. That is to say, if you are looking at the scanner from the front or top, the aiming bulls are not visible.
•With the DR-C225 and DR-C125 the targets are loaded such that the bottom of the targets are feed into the scanner first. The aiming bulls should face forward. That is to say, if you are looking at the scanner from the front, the aiming bulls are visible and the targets are right side up.
•With the DR-6010C and DR-4010C the targets are loaded such that the top of the targets are feed into the scanner first. The aiming bulls are facing up. That is to say, if you are looking at the scanner from the top, the aiming bulls are visible.
If the scanner's document guides are not flush with the targets, the target can get scanned at an odd angle. Too large of an angle and the result image's dimensions may be off. Simply make sure the guides are flush with the targets.
