If you are over 50 and/or wash your hands frequently you may not have fingerprints. The Oregon State Police fingerprint technicians know this and I would hope that information has trickled down to the Marion County Sheriff as well. If so, the sheriff does not appear to have incorporated this into their procedures in order to comply with the state laws stating delivery is to be made within 45 days. If the fingerprints taken by the sheriff are rejected by the OSP you may be required to have the OSP do a second set. This may delay delivery of your CHL and WILL cost you an extra $20. If you suspect you fall into this category you may want to check and see if you can benefit by bypassing the Sheriff and going directly to the OSP where they have an electronic scanning system that allows previewing of the prints. Might save time, but they will probably end up charging the extra $20 anyway.
