Failure to recognize a fingerprint has a 99% chance of being a bad or poor quality enrollment. If you have a poor enroll this will considerably effect the performance of the lock in everyday use.
1. If you are using the Windows software to enroll make sure you do all 9 prints and use the same finger for all of them (this is likely contrary to your original instructions, keep in mind this is to improve any situation where there are recognition issues). Make sure they move their hand away from the scanner for each scan. If a user gives specific trouble you can always add them a second time (this is extremely rarely required), the lock stores up to 1000 users so a duplicate is usually a no big deal.
2. You can move the lock sensitivity from 7 to 9 in the lock setup menu in the software as well, this significantly increases the odds of a match for this user. Remember if it’s set to 7 or another number in the software it will cause any changes like this you make to the lock to match so make it 9 in the software, insure it’s 9 in the lock after you upload. Sometimes people incorrectly think moving the number to a lower value makes it more friendly.
3. If you have our fingerprint enhancement pads (2 of them should have been in each box) you can wipe the users finger lightly with one of those before enrollment, this nearly doubles that users data that is stored. If you don’t have any a light lotion can help insuring the fingers are not overly dry. Remember this is only needed for the enrollment as once you have good quality enrolls daily recognition will be much easier.
4. Look at the users finger carefully and choose the finger with the most visible ridge definition –it does not have to be the typical right index finger, often the right or left ring finger will be higher quality. In fact we show you the scanned graphic on the screen so you can identify when the quality is low. It’s best you don’t click to accept prints that show as an undefined mass, look for the ridge definition in the graphic itself when you view it.
5. Make sure you are not scanning the fingerprints upside-down, this will cause a 75% degradation of the recognition. The USB scanner aperture should be facing *away from you when you enroll. Wrap your finger over it as you would a mouse.
6. If all else fails you can create additional users that are actually the same user, you can also try enrolling that user directly on the lock. We have countless installs where we have large networks of locks and many thousands of users operating very nicely. Invariably when you have a lot of users there are always a small percentage that require the extra effort insuring you have high quality enrolls as described above.
Special Note: In the event the lock was matching fingerprints well and at an acceptable rate but *after you added new users the rate of recognition went down this can be caused by a bad enrollment. If you had a recent user you added that was particularly difficult to enroll you can delete that user and test to see if the recognition rate moves back to the original high rate. For this user enroll using a different finger.
The latest version of the software is called the RUMS kit (compatible with any green scanner lock and any Actuator Systems green scanner type usb fingerprint device.). You can download the free trial of the new software here: http://rums.advancedactuators.com/update/publish.htm (if you are upgrading to the new software make *certain you backup your data using the Maintain menu to an .L32 file before proceding).
